The football fish is famous as being the first deep-sea angler fish. The first sighting of this fish was caught in Greenland in 1883. This one was measured at 22-inches long - the biggest one found to date. Since no females of this species have ever been found bearing parasitic males, biologists assume they are fertilized by free-swimming mates.

The Oarfish is a very largely elongated fish. There have been cases (as seen in the above picture) of extremely long Oarfish, but for the most part they are about a few meters long. They are a family of the Lampriform fish.

The Crinoid is an ancient creature that stems from the echinoderm family and is a relative of the starfish. This peculiar looking creature appear very plant-like and resembles an aquatic fern. The Crinoid coils its legs very gracefully, as seen in the picture above, and uses its legs to trap small plankton and other debris.

This unusual looking fish is called the chimaera. It is a cartilaginous fish, which mean it is composed entirely of cartilage! It uses its long snout to scan the electrical impulses of its prey on the bottom of the sea floor.

This 50-foot dinosaur was excavated last summer on Norway’s Arctic island. The Monster likely represents the biggest species of pliosaur known to science, said Jørn Hurum, of the Natural History Museum in Oslo, Norway, who led the dig team—and who called the reptile “the T. rex of the ocean.”

Pilosaurs were the top marine predators, but unfortunately, not many fossils were found up until now.

Named the “the Monster,” this newly identified fossil predator is one of the largest marine reptiles ever found.

Caretakers at a British aquarium recently discovered that one of its newest residents, an octopus named Henry, had six legs instead of the usual eight. Apparently the caretakers have researched everywhere to see if there really is such thing, but so far, the only documented six-legged octopus is this one! Therefore, they dubbed him hexapus instead of octopus! The creature doesn’t seem to be of a new species, or been through an accident of any sort, therefore this was caused by some sort of genetic mutation.

Believe it or not, these things that look like glass tulips are actually animals. Found in the murky waters of Antarctica, these curious animals are called tunicates.

The plankton-eating tunicates grow up to 3.2 feet (1 meter) long, and filter food by pumping it through an internal mesh structure. The stalk is supported by pressure created by their pump, according to the scientists.

This incredible fish was found in the Alaskan waters and is believed to be one of the oldest fish ever found in the waters. Commercial fishers in the Bering Sea hauled in the female shortraker rockfish seen above, which scientists say was between 90 and 115 years old, in March 2007.

A Seattle, Washington-based ship caught the 44-inch-long (112-centimeter-long), 60-pound (27-kilogram) fish while trawling for pollock at about 2,100 feet (640 meters) below the surface. The massive mama was among ten shortrakers pulled from the depths along with roughly 75 tons of the smaller commercially fished species.

The fish’s age and size both approach the maximum known limits for shortrakers. The largest on record measured 47 inches (119 centimeters) long, and the oldest ever caught was 157 years.

The Mexican axolotl salamander is a distinct amphibian since it retains its larval features all through adulthood. This condition is called neoteny, which means it keeps its tadpole-like dorsal fin that runs almost the length of its body, and its feathery external gills, which protrude from the back of its wide head.

This rare species is found exclusively in the lake complex of Xochimilco, near Mexico city. The axolotl differs from other amphibians since it spends its entire life in the water, mostly at the bottom of the lake. On rare occasions, an axolotl will come out of the water once it has matured.

Since the Mexican axolotl is a close relative of the tiger salamander, it can get quite big, reaching up to a foot in length. Most of these species are black or mottled brown, but albino and white varieties aren’t uncommon in captive environments.
