The white-ring garden eel (Heteroconger canabus), also known as the Cape garden eel in Mexico, is an eel in the family Congridae (conger/garden eels). It was described by Garry I. McTaggart-Cowan and Richard Heinrich Rosenblatt in 1974, originally under the genus Taenioconger. It is a marine, tropical eel which is known from the Gulf of California, in the eastern central Pacific Ocean. It is known to dwell at a depth of 20 m (66 ft), and inhabits sand sediments near reefs, where it forms burrows in nonmigratory colonies. Males can reach a maximum total length of 80 cm (31 in).
