Biology     Glossary (e.g. epibenthic)

Adults inhabit coral and rocky reefs, juveniles often commensal with large sea anemones, sea urchins, or small coral heads (Ref. 4391, 48636). They occur in small to large aggregations. Stomach contents include algae, copepods, and other planktonic crustaceans (Ref. 7247). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

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

Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Courtship characterized by male 'signal-jumping'. Captive pair reported to spawn thrice monthly with a total of 17 over a 7-month period (Ref. 2856).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.03388 (0.02119 - 0.05418), b=3.00 (2.87 - 3.13), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.10 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Fec=20,000-25,000).
Vulnerability (Ref. 59153):  Low vulnerability (10 of 100) .
Price category (Ref. 80766):   Unknown.
