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

Pacific Ocean: known only from the Hawaiian Islands, Cook Islands, New Caledonia, and Okinawa, Japan but probably widespread in the area. Recently recorded from Tonga (Ref. 53797). Eastern Indian Ocean: Scott Reefs, northwestern Australia (Ref. 82665).

Biology     Glossary (e.g. epibenthic)

Adults are found on rocky bottoms in relatively deep water (Ref. 55). Marketed fresh (Ref. 55).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01318 (0.00593 - 0.02930), b=2.94 (2.75 - 3.13), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate vulnerability (44 of 100) .
Price category (Ref. 80766):   Very high.
