Morphology | Morphometrics
(total): 26-35. Preorbital bone appears as broad plate in front of eye (Ref. 26938).
Western Atlantic: disjunct distribution from Bermuda and Chesapeake Bay (USA), including the northern Gulf of Mexico, the Bahamas, and the western Caribbean Sea (Ref. 37039), to Panama.
Abundant in seagrass beds along coasts. Northern populations move offshore during colder months (Ref. 26938). 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=0.00042 (0.00018 - 0.00097), b=3.12 (2.94 - 3.30), based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.5 ±0.6 se; Based on diet studies.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (13 of 100) .
