Marine; demersal; depth range 24 - 133 m (Ref. 26268), usually 31 - 70 m (Ref. 26268). Tropical, preferred ?; 35°N - 5°N, 100°W - 55°W (Ref. 26268)
Western Atlantic: Straits of Florida in the eastern Gulf of Mexico but most common west and south of Mississippi Delta on the inner continental shelf to Guyana.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 9.0 cm TL male/unsexed; (Ref. 7251)

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=0.00661 (0.00304 - 0.01436), b=3.12 (2.93 - 3.31), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 3.2 ±0.4 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 (13 of 100) .
