Embiotocidae (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.

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
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).
