Eels are enemies that appear in Tomb Raider II. They come in two different types: long yellow ones and a giant black one. Both eels can't be killed so Lara must avoid them. The yellow eels'll bite Lara, causing little damage and the big eels hide in small caves in the water and bite Lara, causing big damage.
A variant of eels , an Electric Eel appears in Tomb Raider (Game Boy Color).
