Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 22 - 25; Raggi anali molli: 4. Superior trunk and tail ridges discontinuous; inferior trunk ridge ending on anal ring; lateral trunk ridge continuous with inferior tail ridge; body rings 16; tail rings 21-23.
Body shape (shape guide): eel-like; Cross section: angular.
Found in tide pools and reef crevices. Also found in sheltered inner reefs, usually in caves with sponges and below large plate corals. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).
