Eastern Atlantic: Azores and Morocco to South Africa, including western Mediterranean (off Algeria). Western Atlantic: Gulf of Mexico, Caribbean, and off Lesser Antilles.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 60.0 cm TL male/unsexed; (Ref. 4448)

Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 8-9. Body is compressed (Ref. 37108). Pinkish with silvery reflections, darker dorsally (Ref. 3974). Lacks the checkerboard pattern of whitish and brown, produced by concentration of pigment at the margins of the scale pockets (Ref. 37108).

Biology     Glossary (e.g. epibenthic)

The shallowest-occurring halosaur in the Atlantic. May form aggregations. Feeds on polychaetes, sipunculids, crustaceans and fish.

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 4.2 - 11, mean 6.3 (based on 255 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00087 (0.00033 - 0.00231), b=3.07 (2.84 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.48 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (35 of 100) .
