The bulk of this species’ diet consists of fish in the teleost infraclass, including dragonfish, rattails, anglerfish, and more. They are also known to feed on crustaceans and cephalopods like squid.

These sharks will prey on fish found both on the sea floor and in the water column. Because they are so slow moving, scientists believe these sharks are ambush predators. Their pinkish-red skin actually blends in when in the deep sea.

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
