Fish drop has the ability to withstand the high pressure of these depths because your body is actually a gelatinous mass with a density slightly less than the water of the sea. This gives you the ability to float and swim on the seabed without hardly spending power.
They are not very active. In fact, most of the food, sea urchins, molluscs and crustaceans, simply floats next to them. This deep-water fish, simply pick and choose what to eat. Drop fish are often caught in trawl nets, What makes it an endangered species and is currently in danger of extinction.
