Cuvier's beaked whale
A whale retrieved in Monterey in 2015 was observed to have eaten 200 squids, five fish, and one very deep-sea shrimp. The shrimp and most of the squid were seemingly "bathypelagic," and the fish were giant grenadiers off the "bentopelagic" ocean bottoms. It appears that Cuvier's beaked whale prefers diving deep and using its suction process to acquire fish. The "melon" of the whale, the bump on top of its head, contains its organ for echolocation. This means the whale can use sound waves to locate potential sources of food, which is helpful in the deep sea, where there is no sunlight. This deep diving with echolocation seems to help Cuvier's beaked whales avoid competition for their prey.
