Appearance
Tautog are brown and dark olive, with white blotches, and have plump, elongated bodies. They have a typical weight of 0.5 to 1.5 kg (1 to 3 lb) and reach a maximum length and weight of 90 cm (3 ft) and 13.1 kg (28 lb 14 oz), respectively.
Tautog have many adaptations to life in and around rocky areas. They have thick, rubbery lips and powerful jaws. The backs of their throats contain a set of teeth resembling molars. Together, these are used to pick and crush prey such as mollusks and crustaceans. Their skin also has a rubbery quality with a heavy slime covering, which helps to protect them when swimming among rocks.
