Max length : 32.0 cm WD male/unsexed; (Ref. 114953 )

Biology     Glossary (e.g. epibenthic)

A poorly known species; attains at least 32 cm DW, mature at this size (Ref. 114953 ). 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 based on models

Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00646 (0.00265 - 0.01571), b=3.06 (2.86 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.7   ±0.5 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100). Fishing Vulnerability (Ref. 59153 ):  Very high vulnerability (90 of 100).
