The majority of garden eels live in the Indo-Pacific, but species are also found in warmer parts of the Atlantic Ocean and East Pacific. These small eels live in burrows on the sea floor and get their name from their practice of poking their heads from their burrows while most of their bodies remain hidden.
Since they tend to live in groups, the many eel heads 'growing' from the sea floor resemble the plants in a garden. The garden eel is harmless and actually pretty cute. But get a bunch of them together and things start looking a wee bit creepy.
