About Batman Stingray

Stingrays are sensitive animals and they could not endure that type of mutilation.  Stingrays also have an amazing ability to regenerate their disc, which would further recognize 'batman rays' to be a developmental disfunction.

Batman Rays are the result of a defect during embryonic development of the disc.  The frontal area of the disc fails to fuse together.  This morph is very uncommon, and no one to date has been able to reproduce these rays with success.  Much like Albino or Xanthic morphs, these rays are a genetic misfit, and are usually only birthed in captivity because the survival rate of a deficient animal in the wild is next to none.  This is due to predation and competition for food. They live just normal stingray and needing the same fish supplies.

The so-called ‘Batman’ stingray morphology. The disk failed

to fuse in front of the head during embryonic development of

this Potamotrygon motoro.

These rays move, eat, and act like normal stingrays.  Special care must be provided as they tend to have a harder time competing for food.  Beyond the few that are being kept in captivity, very little is known about the Batman Ray.  We can assume that it is a genetic mutation, similar to a 'cleft lip' in a human, and that it is in no way man-made.  These stingrays demand a very high price due to rarity.

There is no known genetic component to cleft lips in humans, and batman morphology in stingrays almost certainly has nothing to do with genetics.

Sharks: made to hunt predators

• Sharks have been around for about 400 million years - long before dinosaurs even existed.
• Sharks apparently are the only animals that never get sick. They are immune to every type of disease including cancer.
• Sharks have the most powerful jaws on the planet.
• Sharks never run out of teeth. If one is lost, another spins forward from the rows and rows of backup teeth.
• A shark may use over 20,000 teeth during its life.
• A sharks skeleton is made of cartilage, allowing greater flexibility.
• The most harmless sharks tend to be the largest, such as the Basking Shark, the Whale Shark and the Megamouth Shark.
• Two-thirds of a Sharks brain is dedicated to the sense of smell.
• Shark skin is made of denticles instead of ordinary fish scales.

Kingdom: Animalia
Phylum: Chordata
Class: Chondrichthyes
Subclass: Elasmobranchii
Superorder: Selachimorpha

Sharks (superorder Selachimorpha) are a type of fish with a full cartilaginous skeleton and a highly streamlined body. They respire with the use of five to seven gill slits. Sharks have a covering of dermal denticles that protect their skin from damage and parasites and improve fluid dynamics; they also have replaceable teeth. Sharks range in size from the small dwarf lanternshark, Etmopterus perryi, a deep sea species of only 17 centimeters (7 in) in length, to the whale shark, Rhincodon typus, the largest fish, which grows to a length of approximately 12 metres (39 ft) and which feeds only on plankton, squid, and small fish through filter feeding.

Lobsters: Incredible animal body

• It takes a lobster about seven years to grow to be one pound.
• Lobster blood is a clear fluid. When the animal is boiled, the blood turns to an opaque whitish gel. It has no discernible flavor and is perfectly safe to eat.
• Lobsters can regenerate legs, claws, and antennae.
• Lobsters molt (shed their shells) to grow.
• Lobster larva will molt about six times while still in the egg.
• Lobsters exhibit 'handedness'. Some lobsters will have the crusher claw on the right side while others will have it on the left.
• Lobsters may come in a variety of colors besides the usual blue-green, including blue, yellow, red, and white. ome even come in two colors, having half of their shell one color and the other half a totally different color. Of these only the white ones (true albinos) don't turn red when cooked.
• The nervous system of a lobster is decentralized and has been likened to that of a grasshopper.

Kingdom: Animalia
Phylum: Arthropoda
Subphylum: Crustacea
Class: Malacostraca
Order: Decapoda
Infraorder: Astacidea
Family: Nephropidae

Lobsters are invertebrates, members of the Class Crustacea of the Phylum Arthropoda. This class includes animals without backbones and with hard shells like crab, shrimp, crayfish, water fleas and wood lice. A male lobster is called a cock and a female a hen or chicken (when she weighs about 1 pound). Lobsters are sexed by examining the first set of appendages behind the walkers. The male (gonopeds) are bony while the same appendages on the female are feathery. In both cases, you have to look closely because sometimes they are folded up tightly under the body. With a little practice, you can also tell by looking at the tail. On females the tail is relatively broad compared to the male's to accommodate the egg mass.

There are two kinds of lobsters, the "true" lobster (also called American lobster) and the spiny lobster. The true lobster has claws on the first four legs, lacking in the spiny lobster. The spiny lobster has a pair of horns above the eyes, lacking in the true lobster. Spiny lobsters also have two large cream-colored spots on the top of the second segment of the tail. Lobsters regenerate, in fact they can amputate their own claws and legs (autotomy) to escape danger. The term 'amputate' can be in the passive sense as well. I've seen a lobster spontaneously drop a claw for no apparent reason. The lobster's body has 19 parts, each covered by a section of the shell. The shell is thin and soft where the parts join, so lobsters can bend their body and move about. Lobsters breathe through gills located beneath the shell on both sides of their thorax (center part). Lobsters eyes are compound eyes, consisting of hundreds of lenses joined together on the ends of pair of jointed organs called stalks. The four small antennae on the front of their heads are used to "smell" their food or chemicals in the water. The tiny sensory hairs along their legs are used to "taste" their food. Lobsters keep their antennae and eye stalks moving constantly to search for food and to watch for enemies.

True lobsters have two very powerful claws. One claw is sharp and used for cutting, the other is bony and used for crushing. Lobsters that have their heavy ("crusher") claw on the right are considered "right-handed" and the others are "left-handed". Some lobsters are ambidextrous, they usually favor the claw that is the largest. Lobsters can lose claws, legs, eyes and antennae through accident or self-defense, but are able to regenerate them. Lobsters often fight with other lobsters for territory. If another lobster seizes their claw, they may drop their claw to escape. Sometimes, the more aggressive lobster will tear the claw of the opponent off. A lobster with a claw missing is called a cull It takes about 3 to 4 molt cycles for the claw to grow back to full size. Lobsters have a sophisticated nervous system that allows it to sense actions that will cause it harm and feel pain. Lobsters don't have an autonomic nervous system that puts it into a state of shock when it is harmed. For this reason, they will feel pain until their nervous system is completely destroyed. After they are released from the mother's swimmerettes and hatch, the larva will float freely in the water column and molt several more times before taking the form that we recognize as a lobster. At this point they may be only 1/4" in length.

Before they shed the old shell, they will form a thin one underneath. Growing lobsters secrete enzymes that soften the shell and connective shell joints. The shell spilts up the back and the creature backs out leaving it behind...including the membrane that covered the eyes. They will increase their size by about 20% at every molt. By the time a lobster is of legal size, it will have molted about 20-25 times, averaging 4-5 molts a year. After a molt the animal is vulnerable because the new shell is very soft. It will hide among the rocks on the bottom for 6-8 weeks until its shell hardens enough to offer some protection. They often eat their old shell which will replenish the lost calcium and speed up the hardening of the new shell. A young, immature lobster (first 5-7 years) will molt about 25 times a year. An adult male lobster molts twice a year and an adult female lobster once a year, usually in the summer. When lobsters get older, they will molt only once every 3-4 years. The only way to gauge the exact age of a lobster would be by their shell. However, since lobsters shed their shells so often, it is impossible to determine their age. Knowledge of body size at age makes scientists believe that lobsters can attain a maximum age of 100 years. The normal life span is about 15 years. Lobsters can grow to be 3 feet long in overall body length.

Dragonfly: amazing insect predator

• Dragonflies are one of the fastest insects, flying 50 to 60 mph.
• Dragonfly eyes contain up to 30,000 individual lenses. Human eyes only have one.
• Dragonflies only flap their wings at about 30 beats per second (bps) compared to a bee’s 300 bps.
• Dragonflies have two sets of wings. They don’t have to beat their wings in unison like other insects do. Their front wings can be going up while their backs ones are going down.
• Although 80% of the brain is devoted to sight, dragonflies are not able to register detail well.
• Excellent and strong fliers, dragonfly can loop-the-loop, hover, and fly backwards.
• There are nearly 2500 different species of dragonflies.

Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Odonata
Suborder: Epiprocta
Infraorder: Anisoptera

Dragonflies have been around 300 million years. One prehistoric fossil had a wingspan of 2 1/2 feet! Today, the largest dragonfly is found in Costa Rica. It has a wingspan of 7 1/2 inches. Below you’ll find more interesting facts about dragonflies.

Female dragonfly lay eggs sometimes as many 100,000 at a time. Dragonflies typically eat mosquitoes, and other small insects like flies, bees, ants and butterflies. They are therefore valued as predators, since they help control populations of harmful insects. Dragonflies are usually found around lakes, ponds, streams and wetlands because their larvae, known as "nymphs", are aquatic. While underwater they eat mosquito nymphs, tiny fish, and pollywogs. When they have matured to airborne insects, they catch mosquitoes and gnats in mid-air before devouring them. Surprisingly, dragonflies will spend only a very short part of their life span as actual dragonflies. They will live as nymphs for up to four years, shedding their skin up to fifteen times, yet when they finally mature into adults, the dragonfly stage, they will survive only a few months.

Electric Eels - shocking water predators

An electric eel can produce a shock of up to 650 volts.
Electric eels cannot get enough oxygen from water. Approximately every five minutes, they must surface to breathe, or they will drown.
Electric Eels can swim both backwards and forwards.
Electric Eels have poor eyesight, but can emit a low-level charge, less than 10 volts, which they use like radar to navigate and locate prey.

Scientific classification
Kingdom: Animalia
Phylum: Chordata
Class: Osteichthyes
Order: Gymnotiformes
Family: Gymnotidae
Genus: Electrophorus
Species: E. electricus

Electrophorus electricus or Electric Eels are fascinating and famous freshwater predators get their name from the enormous electrical charge they can generate to stun/immobilize prey and dissuade predators. Their bodies contain electric organs with about 6,000 specialized cells called electrolytes that store power like tiny batteries. When threatened or attacking prey, these cells will discharge simultaneously, emitting a burst of at least 600 volts. The electric organ, which consists of a series of modified tail muscles, is similar to a row of batteries connected in a series. It is subdivided into three sections: two small and one large. One small battery is used for navigational signals. The large battery and the other small one is used to generate the stunning discharge. After delivering a strong shock, the electric eel must then allow the electric organ to recharge. Batteries have to be recharged using an external source of energy; in the electric eel the energy to recharge the electric organ comes from the fish's metabolism.

Despite their serpentine appearance, electric eels are not actually eels, their scientific classification is closer to carp and catfish. They are spread in the South America in Guianas then in the Orinoco and the Amazon basin. It has got long and rounded body with small eyes. Its colour is dark brown. The eel can be up to 2.4 m (8 feet) long. The electric eel does not have any pelvic, dorsal or tail fin. Because of that its swimming can also be called as wriggling because its movements are made by the anal fin. An adult eel feeds on small fishes and young eels eat insects.

Goldfish - incredible eyesight

A goldfish is the only animal that can see infrared and ultraviolet light.

Kingdom: Animalia
Phylum: Chordata
Class: Actinopterygii
Order: Cypriniformes
Family: Cyprinidae
Genus: Carassius
Species: C. auratus
Subspecies: C. a. auratus/C. a. gibelio

Goldfish are one of the most common types of fish. They come in different varieties such as Ryukin, Fantail, Oranda and many others. Some goldfish look like they have bubbles of skin covering their eyes. Goldfish can live to be 5 to 10 years old. The average goldfish lives to be around 4 years old and can grow to be 6 inches plus. Goldfish originated in China with several hundred varieties developing over the years. They arrived in the United States somewhere between the 18th and 19th century and have became the most common pet found in households today! They have been kept as pets longer than any other species of fish. Although there are many varieties, all goldfish actually belong to just one species: Carassius auratus. Because of this, goldfish are similar in their behavior, required care, and habits. Goldfish are not tropical fish; therefore, they do not require tropical temperatures such as some fish with temperatures of 80F and higher.

Goldfish are quite intelligent and will recognize the person who feeds them, research show that goldfish have a memory-span of at least three months and can distinguish between different shapes, colors and sounds. They will show they know you by swimming rapidly back and forth when you are near the tank or splashing. Goldfish like to play and benefit from the exercise, so having two fish is better than one. There are several varieties of goldfish; however, they all stem from the original stocks developed by Chinese, Korean, and Japanese breeders. Names are sometimes a hard thing to decide on due to the fact that different cultures call the same fish by different names. Goldfish come in many variations with different colors, single-tails, double-tails, various body shapes, head shapes from pointed to square, and various other mutations such as telescoped eyes.

Goldfish Vision:

Vision that is seen in the goldfish may not seem important to many people, but it is actually quite fascinating in that it is much more developed than most people would expect it to be for the size and apparent intelligence of the creature. Overall, goldfish have developed full-spectrum vision so that they will be able to see the micro-flashes of static electrical charge and bio-luminescence that appear when a creature hunting with sonar sends sound waves through waters rich in micro-fauna in order to search for its prey. This full-spectrum vision has also proved to be very effective in sensing many and various tell-tale signs that come from the bow-wave that a rapidly moving predator makes as it cuts through the water.

Goldfish, in particular, have been widely used as a model system for the study of color vision. The goldfish retina contains rods and four cone types in juveniles, three cone types in adults. The majority of goldfish retina ganglion cells have center-surround organization and many are wavelength opponent goldfish evidence photopic spectral sensitivity functions reflecting both wavelength additive mechanisms and wavelength opponent mechanisms. Goldfish wavelength discrimination has been reported in many studies and found out to exhibit color constancy. the goldfish first developed full spectrum vision in order to see the micro-flashes of bio-luminescence and static electrical charges that tend to discharge when a sonar-hunter sends sound waves through micro-fauna rich waters in search of prey. It also proved effective in sensing various tell-tales that result from the bow-wave of a fast moving predator... Only later did they realize that they could track submarines, intercept trace reflections of communication lasers that took bad bounces of atmospheric interference, and even decode the ultra-faint eminations that are shed of trans-oceanic communication cables, and so much more.

Polar Bears - world's largest land predator

Polar Bears are capable of jumping as high as 6 feet and can run as fast as 25mph. The polar bear or the sea/ice bear are the world's largest land predators.

Domain: Eukarya
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Ursidae
Genus: Ursus
Species: U. maritimus

The world's largest land predator, Polar bears grow twice as big as the Siberian Tigers. Male polar bears may grow 10 feet tall and weigh over 1400 pounds. Females reach seven feet and weigh 650 pounds. In the wild polar bears live up to age 25. Their skin, nose and lips are black in color. Their fur is thicker than any other bears’ even covering their feet, for warmth and traction on ice. Polar bears also have a thick layer of blubber which provides buoyancy and insulation. Despite what we think, a polar bear's fur is not white. Each hair is clear hollow tube. Polar bears look white because each hollow hair reflects the light. On sunny days, it traps the sun's infrared heat and keeps the bear warm at 98 degrees F (when they're resting). Polar bear fur is oily and water repellent. The hairs don't mat when wet, allowing the polar bears to easily shake free of water and any ice that may form after swimming.

They have wide front paws with slightly webbed toes that help them swim. Polar bears’ long neck and narrow skull aid in streamlining the animal in water, and their large, flat and oar-like front feet make them strong swimmers. They paddle with their front feet and steer with their hind feet. Paw pads with rough surfaces help prevent polar bears from slipping up on the ice. The Polar bears have been known to swim 100 miles (161 kilometers) at a stretch.

Polar bears primarily eat seals. They often rest silently at a seal’s breathing hole in the ice, waiting for a seal in the water to surface. Once the seal comes up, the bear will spring and sink its jagged teeth into the seal’s head. Sometimes the polar bear stalks its prey. It may see a seal lying near its breathing hole and slowly move toward it, then charge it, biting its head or grabbing it with its massive claws. A polar bear may also hunt by swimming beneath the ice.

Humans are the polar bears only predator. Baby polar bears often starve. In fact, 70 percent do not live to their third birthday. Sometimes seals are hard to find, especially in the summer when the ice has melted. All across the Arctic, man is moving in to mine oil and coal and there is less space for the polar bear to live. Oil spills can be very dangerous. A bear with oil on its coat cannot regulate its body temperature properly. If the bear eats the oil while grooming it could die. Man made pollution is also a cause of death. At each stage of the food chain, pollutants get more concentrated. By the end when the polar bear eats the seal and it could be lethal.

Whale Shark - teeth of the largest living fish

The whale shark has over 4,000 teeth. Each tooth is only 3mm long.

Kingdom: Animalia
Phylum: Chordata
Class: Chondrichthyes
Subclass: Elasmobranchii
Order: Orectolobiformes
Family: Rhincodontidae
Genus: Rhincodon
Species: R. typus
Common Name: Whale Shark

Teeth minute, about 300 rows in each jaw. An individual tooth has a single, hooked cusp. Teeth appear to play no role in feeding. Instead, it is a suction filter feeder - it sucks in a huge volume of water and plankton. The water is strained through spongy tissues supported by cartilaginous rods between the whale shark's gill arches. The plankton, trapped in the gill rakers, is then swallowed. Sometimes larger fishes - such as mackerels, anchovies, and tunas - are sucked in as well. A whale shark can filter 1.5 million liters (400,000 gallons) of water an hour when feeding. The whale shark has unique denticles (tooth-like scales structures), each with an extremely strong central keel, no lateral keels, and a tri-lobed rear margin. It would appear that the denticles are hydrodynamically important in its pelagic lifestyle.

About Whale Sharks:
The whale shark is the largest living fish today. Maximum size is thought to be 20m. The smallest free-living individuals are from 55cm (21.7 inches) long. Sexual maturity in both sexes may not occur until the sharks are over 9m in length. Age estimates for whale sharks are as high as 60 years, but no one really knows how long this species lives.

Based on the study of a single egg recovered off the coast of Mexico in 1956, it was believed to be oviparous, but the capture of a female in July 1996 which was pregnant with 300 pups indicates that they are ovoviviparous. In 1995, an 11-meter female whale shark was harpooned off the eastern coast of Taiwan and 300 fetal specimens, ranging in length from 42 to 63cm, were taken from the two uteri. This discovery proved that the species is a live bearer, with an ovoviviparous mode of development. The egg-capsules of this whale shark were amber colored, with a smooth texture, and possessed a respiratory fissure (opening) on each side.

Giant Squid - world's larget eyes

"A giant squid’s eyes have a diameter of 15 inches which are the largest of any animal."

Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda
Subclass: Coleoidea
Order: Teuthida
Suborder: Oegopsina
Family: Architeuthidae
Genus: Architeuthis

Giant squid have a sophisticated nervous system and complex brain, attracting great interest from scientists. They also have the largest eyes of any living creature except perhaps colossal squid — over 30 centimeters (1 ft) in diameter. Large eyes can better detect light (including bioluminescent light), which is scarce in deep water. Architeuthis) is a deep-ocean dwelling squid in the family Architeuthidae, represented by as many as eight species. Aristotle, who lived in the fourth century B.C., already described a large squid, which he called teuthus, distinguishing it from the smaller squid, the teuthis. He mentions that "of the calamaries the so-called teuthus is much bigger than the teuthis; for teuthi [plural of teuthus] have been found as much as five ells long."

- Researchers defrosting two colossal squid at New Zealand's national museum
- The larger one has eyes around 27 cm across, believed to be world's biggest
- It weighs almost half a tonne and measures about 32 feet (10 meters) in length
- Scientists believe that there may be even larger colossal squids in existence


Article from Wikipedia about Giant Squid:

The giant squid (genus: Architeuthis) is a deep-ocean dwelling squid in the family Architeuthidae, represented by as many as eight species. Giant squid can grow to a tremendous size: recent estimates put the maximum size at 13 metres (43 ft) for females and 10 metres (33 ft) for males from caudal fin to the tip of the two long tentacles (second only to the colossal squid at an estimated 14 metres (46 ft), one of the largest living organisms). The mantle is about 2 metres (7 ft) long (more for females, less for males), and the length of the squid excluding its tentacles is about 5 metres (16 ft). There have been claims reported of specimens of up to 20 metres (66 ft), but no animals of such size have been scientifically documented.

Humpback Whales - World's loudest Creature

Humpback whales create the loudest sound of any living creature.

Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Cetacea
Suborder: Mysticeti
Family: Balaenopteridae
Genus: Megaptera
Species: novaeangliae

Humpback whale (Megaptera novaeangliae) is a Baleen whale. One of the larger rorqual species, adults range in length from 12–16 metres (40–50 ft) and weigh approximately 36,000 kilograms (79,000 lb). The humpback has a distinctive body shape, with unusually long pectoral fins and a knobbly head. It is an acrobatic animal, often breaching and slapping the water. Males produce a complex whale song, which lasts for 10 to 20 minutes and is repeated for hours at a time. The purpose of the song is not yet clear, although it appears to have a role in mating.

Wikipedia Article - Whale song

Both male and female humpback whales can produce sounds, however only the males produce the long, loud, complex "songs" for which the species is famous. Each song consists of several sounds in a low register that vary in amplitude and frequency, and typically lasts from 10 to 20 minutes. Songs may be repeated continuously for several hours; humpback whales have been observed to sing continuously for more than 24 hours at a time. As cetaceans have no vocal cords, whales generate their song by forcing air through their massive nasal cavities.

Whales within an area sing the same song, for example all of the humpback whales of the North Atlantic sing the same song, and those of the North Pacific sing a different song. Each population's song changes slowly over a period of years —never returning to the same sequence of notes.

Scientists are still unsure of the purpose of whale song. Only male humpbacks sing, so it was initially assumed that the purpose of the songs was to attract females. However, many of the whales observed to approach singing whales have been other males, with the meeting resulting in a conflict. Thus, one interpretation is that the whale songs serve as a threat to other males. Some scientists have hypothesized that the song may serve an echolocative function. During the feeding season, humpback whales make altogether different vocalizations, which they use to herd fish into their bubble nets.
