Sarcastic Fringehead
These guys have quite the name, don’t they? This small but extremely hardy fish has a large mouth and a rather aggressive territorial behavior, which is how it got its common name.
Black Swallower
You guessed it, the black swallower got its name due to its uncanny ability to swallow fish larger than itself. Freaky to say the least! You can only find it in depths of 700–2,745 m (2,297–9,006 ft).
