Short Description
Diet: central Mexican Pacific (data base: 175 stomachs were analyzed): The diet of this species was mainly composed of microcrustaceans, such as caridean shrimp and brachyuran and stomatopod larvae (>80% IRI), and differed significantly between seasons (table 2). During period T1 (the warm period, extends from July to December) three main categories were identified: Processidae, stomatopod larvae, and brachyuran larvae (>96% IRI). During period T2 (the cold period extends from January to June) the diet consisted primarily of amphipods, carideans (Ogyriididae and Processidae), Portunus asper, and penaeids (>93% IRI). [13684]

Distribution
Eastern Pacific: Eureka in northern California, USA to Panama. Source: www.gbif.org

Biology
Male grasps disc margin of female, flips under her, and inserts a clasper. Mating lasts about 5 minutes. Occurs on sand or mud bottom off beaches and in bays and sloughs [17050]. Densities of this species were significantly higher at warmer effluent water near the surfzone at Seal Beach, California than to cooler, ambient water further offshore (Ref. 54651). Mobile invertebrate feeder (Ref. 57615). Feeds on benthic invertebrates and small fishes.

Size / Weight / Age
58.0 cm TL (male/unsexed; (Ref. 40637)); max. published weight: 1,360 g (Ref. 4699)

Habitat
demersal; marine; depth range 0 - 91 m [1658], usually ? - 15 m (Ref. 55315)
