Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Distinguished from congeners in Iceland by the following characters: presence of parr marks in adults; flank dark brown with irregular golden or yellow spots, belly beige to yellowish, usually blackish markings on throat (not much difference between breeding and non-breeding coloration); pectoral fins black, other fins beige, caudal and dorsal fins with pale spots; snout blunt, rounded, about equal to eye diameter; mouth subinferior, upper jaw projecting (Ref. 59043).
Inhabits shallow littoral zone, with water 0-10 m deep. A nocturnal species which hides between stones during the day. Feeds predominantly on snails, and to a lesser extend on benthic insects (Ref. 59043).
