Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | Faunafri

Indo-Pacific. Eastern Pacific: southwestern coast of Baja California Sur, Mexico and Gulf of California to Ecuador (Ref. 9283).

Occur in deep lagoon and seaward reefs where they feed by rooting for crustaceans and other invertebrates in the sand. Also feed on small fishes. Small juveniles live among the tentacles of jellyfish (Ref. 9710). Form schools. Noted for their behavior to closely swim around sharks and other large fish, but also following divers (Ref. 10361) to gain protection from likely predators (Ref. 9710). Marketed fresh and salted or dried (Ref. 9283). Juveniles are used in the aquarium trade.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01430 (-0.01509 - 0.04369), b=2.93 (2.92 - 2.95), based on LWR estimates for this species (Ref. 93245).

Trophic Level (Ref. 69278): 3.8 ±0.60 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.14-0.53).

Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100) .

Price category (Ref. 80766): High.
