Black swallower

• Life hack: they have the ability to swallow fish larger than themselves

The black swallower, also known as Chiasmodon niger, is a species of deep sea fish in the family Chiasmodontidae. This is the most common fish species in the North Atlantic. What makes them special is their ability to eat fish larger than themselves.

They are actually small fish, with a maximum length of 25 cm (9.8 in), but with a large mouth and stomach. Their diet consists of bony fish, which are swallowed whole. According to animal experts, the black swallower has the ability to swallow prey over twice its length and ten times its mass.

In 2007, researchers found a dead black swallower with a snake mackerel in its stomach four and a half times its own length.
