#1: Unidentified Parasite Fish
Apparently this fish is a parasite fish that attaches itself to the sides off big fishes like Sharks and Whales, as well as big ships. And freeloads of his hosts by hitching a ride on them. I suppose the huge weird structure on top is the suction design that allows it to attach itself to its host easily.
The Chimaera uses it long nose to look for prey hidden in the sea bed
#3: Sea Pig
The Sea Pig stays at the bottom of the ocean and feed on the microorganisms in the mud of the seafloor.
#4: Blob Fish
The Blob Fish swallows edible matter that floats in front of it such as deep-ocean crustaceans.
The flesh of the blobfish is made of a gelatinous structure with a density less than water, which allows it to float above the sea floor without using any energy on swimming.
Due to its low density flesh, the blobfish’s shape is very different when it is out of water.
#5: Vampire Fish
Vampire fish suck the blood out of other fish. Mouth contains huge suction designs.
#6: Frilled Sharks
#8: Elephant Fish
The elephant fish uses its snout to hunt for food on the muddy sea bottom.
#9: The tongue replacer
The Tongue Replacer is a parasite that attaches itself to a fish’s tongue.
It begins by attaching itself to the fish’s tongue and sucking the fish’s blood through the claws on its front legs.
When it grows bigger, less blood reaches the fish’s tongue.
Slowly, the parasite replaces the tongue and the fish uses it like a normal tongue.
