與出現於相同的區域與到更北方中的 珠光擬梳唇隆頭魚〔Tautogolabrus adspersus〕 區分了, 用它的陡峭, 圓的頭部背面輪廓; 較矮胖的身體; 覆有鱗片的低鰓蓋; 而且腹鰭的比較向後地點。
Found close to shore on hard-bottom habitats, occasionally entering brackish water. Adult male territorial and active during the day to feed and rests in crevices at night. Prefers temperatures above 10°C. Spawning was noted in June-July in Canadian waters, but appears more protracted (April-July) in coastal waters of Virginia, USA. Feeds mainly on mussels, gastropods, other mollusks and crustaceans. This species has gained popularity as a prized food and sport fish (Ref. 6486, 4926, 41297). Investigation on the diel and seasonal activity patterns of the adult tautog in its southern range were conducted using ultrasonic telemetry (Ref. 41297).
發現在底部堅硬的棲息地上接近海岸, 偶然地進入半淡鹹水。 雄性成魚領域性與活躍的在白天期間在裂隙中覓食而且休息在晚上。 偏愛在 10個 ° C. 上面的溫度 產卵在加拿大水域的六月到七月被注意, 但是在美國維吉尼亞的沿岸水域中顯得更伸長的 (四月-七月)。 主要吃貽貝，腹足動物，其他的軟體動物與甲殼動物。 這種已經得到名聲作為一個珍視食用及遊釣的魚.(參考文獻 6486,4926,41297) 在它的南方範圍的在成魚蠔隆頭魚的日週期性而季節性行為模式上的調查被傳導使用超聲波遙感勘測。 (參考文獻 41297)
Spawns in groups or in pairs. Pairing occurs between females and size-dominant males exhibiting strong territoriality and performing a protracted courtship (Ref. 6488). Gonochorism is confirmed for this species (Ref. 103751).西大西洋: 到在美國的南卡羅萊那州的在加拿大的新斯科舍省中的些微以東哈利法克斯; 最豐富的在科德角與德拉瓦州海灣之間。
