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

Eastern Pacific: San Diego in California, USA to Peru including the Galapagos Islands. International trade is monitored through a licensing system (CITES II, since 5.15.04) and a minimum size of 10 cm applies. Reported from the San Francisco Bay by Alexander Agassiz (Ron Fritzsche, pers.comm. 08/09).

Biology     Glossary (e.g. epibenthic)

Nocturnal. Occur in offshore waters, mostly captured by dredging at 10 m or deeper. Occasionally caught at surface. Are often camouflaged within the branches of gorgonians and black coral trees where they are seen to curl their tail around the branches (Ref. 5227). Have been found in the stomachs of Pacific yellowfin tuna and bluefin tuna (Ref. 30915). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Male carries the eggs in a brood pouch (Ref. 205). Gestation period is 14-15 days depending on temperature (Ref. 30915).

Estimates based on models

Preferred temperature (Ref. 123201): 19.1 - 28.5, mean 24.3 °C (based on 131 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00447 (0.00175 - 0.01142), b=3.00 (2.78 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.38 se; based on food items.
