Tiger reef eel
Tiger reef eels are found in reefs in the Pacific and Indian Oceans. They are extremely secretive, and often only seen at night. They often rearrange rocks and sand in order to create good hiding places. Reproduction has been poorly studied, but tiger reef eels are believed to be protogynous hermaphrodites, meaning females transition to males at midlife. Tiger reef eels feed on fish and larger crustaceans such as shrimp and crabs. They grow to 120 cm in length.
