Taxonomic Remarks
Quote Snoeks and Hanssens, 2004 (Ref. 55954): "We tentatively accept the synonymy of T. polyodon (Trewavas, 1935) and T. maculiceps (Ahl, 1927) with this species (T. macrostoma (Regan, 1922)) as suggested by Konings (1996). A definite conclusion cannot be given, as we have not examined the types of these nominal species."

Taille / Poids / Âge
Maturité: Lm ?  range ? - ? cm
Max length : 30.0 cm TL mâle / non sexé; (Ref. 5715)
Found over rocky areas in shallow water (Ref. 267). Piscivore, feeds by moving around rocks and into cracks in search of its unwary prey, the Mbunas, which are quickly snapped up with the large mouth (Ref. 5595).
Cycle de vie et comportement reproducteur
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
Guards offspring for more than 3 weeks. Young become independent when they reach 3.8-4.0 cm SL and are able to move around as solitary hunters in the rocky habitats.
