The enigma garden eel [2] (Heteroconger enigmaticus) is a species of eel in the conger/garden eel family Congridae. [3]
The enigma garden eel was first described in 1999 by Peter Henry John Castle and John Ernest Randall. [4] The species epithet enigmaticus is derived from the Greek 'αινιγματικός' (enigmatikós), meaning 'enigmatic.' [3]
This species is a tropical marine eel that is harmless to humans. It is medium to dark brown in colour. Males can reach a maximum total length of 43.7 cm (17.2 in; 1.43 ft), while females can reach 41.6 cm (16.4 in; 1.36 ft). [3]
The enigma garden eel is found in the western Pacific Ocean, including Indonesia and New Guinea. It dwells at a depth range of 3 to 25 m (9.8 to 82.0 ft), and inhabits regions with dark, silty sand and seagrass ( Holiphila species). Males can reach a maximum total length of 43.7 cm (17.2 in; 1.43 ft), while females can reach 41.6 cm (16.4 in; 1.36 ft). [3]
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.
The spotted garden eel is a heteroconger belonging to the family Congridae. It is native to the Indo-Pacific.
The garden eels are the subfamily Heterocongrinae in the conger eel family Congridae. The majority of the 36 known species of garden eels live in the Indo-Pacific, but can be found in warm ocean water worldwide. These small eels live in burrows on the sea floor and get their name from the behavior 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. They vary in color and size depending on the species. The largest species reaches about 120 cm (47 in) in length, but most species do not surpass 60 cm (24 in). Garden eel colonies can grow as large as one acre in surface area and number up to several thousand individuals.
