Biology     Glossary (e.g. epibenthic)

Found on the continental shelf (Ref. 5316). Enters sheltered muddy estuaries where laying out in the open on the bottom (Ref. 48635). Most specimens from dredge and trawl collections (Ref. 5316). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Solitary on mud bottoms (Ref 90102).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00056 (0.00025 - 0.00128), b=3.10 (2.91 - 3.29), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
Price category (Ref. 80766):   Unknown.
