Eastern Pacific: Sitka, Alaska to southern Baja California in Mexico; the northern population ranges from Alaska to Monterey Bay, southern population from Morro Bay southward.

Size / Weight / Age

Maturity: L_m ? range ? - ? cm
Max length : 32.5 cm TL male/unsexed; (Ref. 93899); 38.5 cm TL (female)

Common in eelgrass of bays and estuaries, sometimes taken in shallow offshore waters (Ref. 5316). Feeds on crustaceans (Ref. 6885). Females larger than males (R.C. de Graaf, pers. Comm., 2001; Ref. 93899). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

A female wraps herself around a male in a rigid vertical S position. Eggs are fertilised in the brood pouch of the male (Ref. 6885).

Estimates based on models

Preferred temperature (Ref. 123201): 8.3 - 18, mean 10.2 °C (based on 254 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00027 (0.00013 - 0.00055), b=3.18 (3.01 - 3.35), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.40 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (tmax=2;).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100).

Price category (Ref. 80766): Unknown.
