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

Indo-Pacific: Red Sea to the Hawaiian, Line, Marquesan, and Tuamoto islands, north to Ryukyu Islands, south to Lord Howe; including Micronesia (Ref. 2334). Range extend to Southeast Atlantic, Algoa Bay, South Africa (Ref. 11228). Most authors misidentified this species as Synodus variegatus (Lacepède).

Biology     Glossary (e.g. epibenthic)

Common on sand or sand-rubble areas of lagoon and seaward reefs to over 20 m depth (Ref. 1602, 9710, 48635). Benthic (Ref. 58302). Frequently buries in sand leaving only eyes and nostrils exposed (Ref. 9710, 48635). Generally solitary (Ref. 1602). Sometimes in pairs or small groups (Ref 90102).

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

Generally solitary, but up to four males may have been observed courting a single larger female. A courting male may station itself atop a female and puff out its opercula and spread its fins in a display of aggression towards other males (Ref. 37816).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00550 (0.00348 - 0.00867), b=3.26 (3.13 - 3.39), based on LWR estimates for species & Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.2   ±0.7 se; Based on diet studies.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (13 of 100) .
Price category (Ref. 80766):   Medium.
