Biology     Glossary (e.g. epibenthic)

Common in clear outer lagoon and seaward reefs, over hard bottoms as well as over sand and rubble. Typical along reef-crests in depths of 1-6 m, but has also been collected from depths of 24 m. Usually seen in pairs, hovering near their burrow. Monogamous (Ref. 52884, 48637). Feeds on small benthic invertebrates, fishes, and fish eggs by sifting mouthfuls of sand.

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

Distinct pairing (Ref. 56363). Females spawn every 13 days while males guard the eggs which are laid in a burrow for 2-3 days (Ref. 56363). Both sexes impose monogamy as a practise by guarding each other against other possible mates (Ref. 56363). Mate guarding is made possible because all males were able to hold a nest site, both sexes exhibit strong site fidelity, and residents have an advantage in contests over mates (Ref. 56363).

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=0.00977 (0.00462 - 0.02067), b=3.05 (2.88 - 3.22), based on LWR estimates for this Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  4.0   ±0.57 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Fec = 60,488).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Very high.
