Embiotocidae (Surfperches)
海鯽科 (Surfperches)
Etymology: Embiotoca: Greek, embios = permanent, for all the life + Greek, tokos,-oy = birth (Ref. 45335); jacksoni: jacksoni for A.C. Jackson , who first noted that black perch bore living young and brought this information to the attention of Alexander Agassiz (Ref. 4930).
Eponymy: A C Jackson, while fishing in San Salita (Sausalito) Bay, California, caught an unusual fish that had living fish inside, which he described as “…perfect miniatures of the mother”. [...] (Ref. 128868), visit book page.

大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 39.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 2850); 最大體重: 700.00 g (Ref. 2850); 最大年齡: 10 年 (Ref. 56049)
Adults chiefly live in rocky areas near kelp, occasionally over sand bottom of coastal bays and around piers and pilings, and rarely in surf. Occur from intertidal areas to 46 m depth, but usually at about 6.1 m. Usually form small groups. Viviparous, female carries the developing young (Ref. 205).
主要地生活在海藻附近的岩石區中, 偶然地在近岸海灣的砂質底部之上與碼頭與樁材的周圍, 而且極少在海浪。 生存於潮間帶的沿岸區域到 46 公尺深, 但是通常於大約 6.1 公尺。 通常形成小群魚群。
