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

Western Central Pacific: Indonesia, Philippines, Papua New Guinea, northern Great Barrier Reef, Solomon Islands, Palau, Vanuatu and Fiji. Recently recorded from Tonga (Ref. 53797).

Biology     Glossary (e.g. epibenthic)

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5020   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.01073 - 0.04672), b=2.97 (2.80 - 3.14), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Medium.
