Honeycomb moray eel
Honeycomb moray eels are widespread throughout the world, from the eastern coast of Africa to the Great Barrier Reef in Australia. They grow to three metres in length. Although they feed mostly on small fish and octopuses, they sometimes catch prey that’s too large to be swallowed. When this happens, the eel will clamp its jaws onto the prey, knot its tail and move the knot towards its head. The knot is then pushed against the prey while the eel’s head pulls back through the knot, enabling the eel to rip off a bite-sized piece of prey.
