Heteroconger is a genus of marine congrid eels. These small, slender garden eels live in groups where each individual has its own burrow. Usually, only the head and front half of the body is visible. The greatest species richness is in the Indo-Pacific, but species are also found in the warmer parts of the Atlantic and the eastern Pacific. Its name relates to how a huge colony of the eels looks swaying in the current.
