Description

The enigma garden eel is a garden eel (Congridae) from the western Indian Ocean. The species grows to about 44 cm but is very thin and lives in colonies: each animal protrudes from a self-dug vertical burrow in the sandy bottom, with the forebody curved into the current to snap at drifting zooplankton. When threatened it quickly withdraws into its burrow. A dense colony looks like a waving garden. The fish is harmless to humans.
