Biologi     Ordlista (t.ex. epibenthic)

Inhabits fine sand to mud bottom, often near kelp beds and sometimes abundant on mud flats of coastal bays. Often buries itself in bottom sediments. Ranges from the intertidal zone to 50 m depth (Ref. 12951). Solitary or in small groups, gathers in shallow bays, lagoons, and off beaches (Ref. 12951, Ref. 114953). Feeds on small sand-dwelling crustaceans, worms and mollusks. Ovoviviparous (Ref. 50449), with 1 to 15 pups in a litter (Ref. 48844), mainly in August (Ref. 114953). Possesses ampullary electroreceptors with a region of maximum sensitivity of 5-15 Hz (Ref. 10011).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 115969): 15.3 - 23.1, mean 20.6 °C (based on 38 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trofisk nivå (Ref. 69278):  3.4   ±0.42 se; based on food items.
Resiliens (Ref. 120179):  Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Fec = 1).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (51 of 100) .
