Tautog

Tautoga onitis

Also known as Blackfish, Oysterfish, Chub

Tautog patrol rocky reefs, boulder fields, and shipwrecks, using heavy, human-like incisors and grinding pharyngeal teeth to crush hard-shelled invertebrates. These sluggish wrasses enter a state of semi-dormancy among bottom crevices when water temperatures plunge in late autumn. Males develop distinct white chins and defend mating territories over structure as water warms each spring.
