The black swallower is a deep-sea fish that gets its name from its dark color and its ability to swallow fish lager than itself. While not too much is known about this fish, it is preyed upon by larger fish, such as sharks, and squid.
The Black Swallower can eat any fish that is bigger than it's own size. I can eat bony fish. In most pictures, a Black Swallower has a snake mackerel in its transparent overstretched stomach.
