Short description Morfologia | Morfometria

Narrow white marginal band around disk; white spot anterior to spiracle and posterior to eye; ventral surface plain; spiral valve with 11-14 turns (Ref. 12693).

Biologia     Glossario (es. epibenthic)

Inhabits sandy bottoms in estuaries and rivers (Ref. 12693). Feeds on bottom-dwelling crustaceans and shellfish. Breeds in fresh water (Ref. 32457). Ovoviviparous (Ref. 50449). Wounds caused by the dorsal spines are extremely painful and can be fatal. Sold fresh for human consumption (Ref. 32457). Total length maybe greater than 200 cm.

Life cycle and mating behavior Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve

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

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00832 (0.00366 - 0.01891), b=3.10 (2.90 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.37 se; based on food items.
Resilienza (Ref. 120179):  Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Assuming Fec<10).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
Price category (Ref. 80766):   Low.
