Short description
Morphology | Morphometrics
Cephalic fins smaller, tail longer without spine (Ref. 7251). Upper surface black (Ref. 6902).
Western Atlantic: New Jersey, USA (Ref. 7251) to Santos, Brazil (Ref. 26340) and Argentina (Ref. 58839). Eastern Atlantic: St. Paul's Rocks (Ref. 13121).
Occurs in shallow coastal waters (Ref. 12951). Feeds mainly on planktonic crustaceans but may take small schooling fishes (Ref. 12951). Ovoviviparous (Ref. 50449). Found singly, in small groups, and in schools (Ref. 12951). Swimming at high speed and often leap high above the surface (Ref. 6902). Flesh has excellent flavor (Ref. 6902). Source of oil.

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00383 (-0.25380 - 0.26146), b=3.09 (2.96 - 3.22), based on LWR estimates for this family-BS (Ref.
93245).
Trophic Level (Ref.
69278): 3.8 ±0.59 se; Based on food items.
Resilience (Ref.
69278): Very Low, minimum population doubling time more than 14 years (Fec=1).
Vulnerability (Ref.
59153): High vulnerability (58 of 100) .
