Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 23 - 25; Raggi dorsali molli (totale) : 3 - 5; Spine anali: 3; Raggi anali molli: 7 - 8. Diagnosis: Eretmodus marksmithi is characterized by a subterminal mouth and 7-8 light bars extending the full depth of the body from dorsal fin base to ventral side, the last crossing the caudal peduncle (Ref. 92306). A few light blue dots may be present, mainly on the head (Ref. 92306).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Found in shallow (1-2 m deep), well-oxygenated, clear water of the surge zone; bottom composed of small stones varying from 10-40 cm in diameter; feeds on biocover which is scraped from rocks; small invertebrates (crustaceans, mites, insects, insect larvae) are eaten as well; biparental mouthbrooder (Ref. 92306).
