Morphology | Morphometrics
Western Atlantic: Maine (USA), Bermuda and northern Gulf of Mexico to Argentina. Nova Scotia, Antilles, western Caribbean from Yucatan to Colombia (Ref. 26938). Taxonomic status of the eastern Atlantic population (from Mauritania to Gabon) needs further study and records from Cape of Good Hope, South Africa and the Indo-Pacific area require confirmation (Ref. 4509).
Associated with floating Sargassum (Ref. 4509). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00083 (0.00041 - 0.00169), b=3.13 (2.96 - 3.30), based on LWR estimates for species & Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.3 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
