Gymnothorax funebris (originally Lycodontis funebris Ranzani 1839) is the extant green moray eel, which has no limbs or fins. Here this traditonal 'eel' is derived from Channa, the snakehead, another cave dweller. Pharygneal jaws (former gill bars) race anteriorly to double capture prey and drag it back to the digestive system. This species lays 10,000 eggs, which are fertilized externally.

Gymnothorax afer (Bloch 1795, type genus; 2m) is the extant dark moray eel.

Eurypharynx pelecanoides (= Gastrostomus Vailiant 1882; up to 75cm long) is the extant deep sea pelican eel or gulper eel. Like its sister, the moray eel, the naris, antorbital fenestra, orbit and temporal fenestra are confluent. Both lack fins. Distinctly the jaw joint is far behind the occiput and hyperelongated hyomandibular and quadrate. The stomach can stretch to accomodate large prey. The muscle segments are V-shaped, not W-shaped. The lateral line system projects from the body, rather than lying in a groove.
