Eastern Atlantic: Mauritania to Angola.

Biology     Glossary (e.g. epibenthic)

Common in marine and estuarine habitats (Ref. 3497). Feeds on shrimps, crabs, bivalves and annelids (Ref. 28587). Ovoviviparous (Ref. 50449).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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). Distinct pairing with embrace (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01202 (0.00492 - 0.02938), b=3.03 (2.81 - 3.25), based on LWR estimates for this (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.50 se; Based on food items.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Vulnerability (Ref. 59153):  High to very high vulnerability (67 of 100) .
Price category (Ref. 80766):   Low.
