The Black Swallower is a rarely seen deep sea fish found at a depth of 2,300-9,000 ft . This fish is known for its ability to swallow a fish up to THREE times its size! It accomplishes this by using its highly stretchable jaw and stomach. The Black Swallower will grab its prey from behind by the tail and then coil it into its stomach where it will be slowly digested. It also has sharp interlocking teeth which keep the prey from swimming away.
