Short description Morfologia | Morfometria

Spine dorsali (totale): 8; Raggi dorsali molli (totale): 12-14; Spine anali 3; Raggi anali molli: 10 - 12. The primary phase of this wrasse is almost indistinguishable from that of T. purpureum. But head of male T. trilobatum plain brown to orange or shaded with blue. Female most difficult and has a more spotted and shorter head. It lacks the 'V' on the snout that shows clearly on the T. purpureum (Ref. 48636). Initial phase with a diagonal dark red line below front of eye (Ref 9823).

Biologia     Glossario (es. epibenthic)

Found solitary or in groups (Ref. 90102) in shallow exposed reef flats, usually with rock-base and mixed coral and algae (Ref. 48636, 58302). Also occurs in surge-swept reef flats, reef margins, and clear rocky shorelines, but may venture to deeper waters up to 10 m (Ref. 3921). Benthopelagic (Ref. 58302). Feeds on crustaceans (especially crabs), mollusks, and ophiuroids (brittle stars) (Ref. 3921).

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
