This is a blue marlin. It is usually found in the open ocean of the pacific ocean. The male fish is about 14 feet long and weighs nearly one ton. The female marlin fish is about 12 feet long and weighs about 1400 pounds. The reason it is called the blue marlin is because it has a blues black back. the blue marlin usually eats small fish like sardines and mackaral. it can eat large groups of small fish at once. These fish are popular for open ocean fishing. I think this fish is really cool.Thanks for looking. Dylan

This is a gulper eel. It is one of the most bizzare creatures in the ocean. It is about 10 feet long. It can swallow something as big as itself. Its mouth can open up about 1-2 feet, so it can swallow lots of fish at the same time, it can even swallow a snipe eel or bigger fish. It lives 5000-6500 feet below the surface of the ocean. It is usually black or dark green in color and sometimes has a white line or groove on either side of the dorsal fin. they have small teeth. Not much is known about the habitat of the Gulper eel. thank you for looking at this eel. Dylan

This is a Mauve Stinger. It is 5 – 12 feet in diamater. It is very poisionous to humans and other fish. they eat small fish and Moon Jellyfish. ¬†They stingers can grow to be 10-12 inches long. They live in the pacific ocean. As you can see it is very colorful. They are not a big species of Jellyfish. These Mauve Stingers live 100 feet to 200 feet down in the ocean. It has lights near the end of its body as you can see in the picture. It is Not the smallest jellyfish (the smallest is the box jellyfish) The Mauve Stinger has a unusually long stinger which most jellyfish don’t have. This Jellyfish has red spots near the top of its body. I thin this jellyfish is really cool. Thank you for looking at this fish. Dylan H

The viperfish is one of the most unusual-looking fish in the deep sea. It is also one of the most popular and well-known species. Known scientifically as Chauliodus sloani, it is one of the fiercest predators of the deep. This fish can be easily recognized by its large mouth and sharp, fang-like teeth. In fact, these fangs are so large that they will not fit inside the mouth. Instead, they curve back very close to the fish’s eyes. The viperfish is thought to use these sharp teeth to impale its victims by swimming at them at high speeds. The first vertebra, right behind the head, is actually designed to act as a shock absorber. This fearsome looking creature has a long dorsal spine that is tipped with a photophore, a light-producing organ. The viperfish uses this light organ to attract its prey through a process known as bioluminescence. By flashing the light on and off, it can be used like a fishing lure to attract smaller fish.

In spite of its ferocious appearance, the viperfish is a relatively small animal, growing to about 11 or 12 inches (30 centimeters) in length. It is usually dark silvery blue in color, but its coloration can vary from green to silver or black. Although the main light organ is located at the end of the elongated dorsal fin ray, there are also several photophores located all along the side of the fish. These may help to camouflage the fish from predators lurking below. These lights make its bottom side appear to blend in with the extremely faint light filtering down from above. They may also serve to attract prey and communicate with potential mates or rivals.

The unusually large teeth of the viperfish help it to grab hold of its prey at it hunts in the darkness. Viperfish have been observed hanging motionless in the water, waving their lures over their heads like a fishing pole to attract their meals. They have a hinged skull, which can be rotated up for swallowing unusually large prey. They also have very large stomachs that allow them to stock up on food whenever it is plentiful. Viperfish feed primarily on crustaceans and small fish. Like many deep-sea creatures, they are known to migrate vertically throughout the day. During daytime hours they are usually found in deep water down to 5,000 feet (1,500 meters). At night they travel up to shallower waters at depths of less than 2,000 feet (600 meters) where food is more plentiful. Viperfish have a very low basal metabolic rate, which means they can go for days without food. This adaptation is likely a result of the scarce nature of food in the deep sea. Viperfish are known to be preyed upon by sharks and some species of dolphin.
