Biology     Glossary (e.g. epibenthic)

Adults are commonly found in intertidal pools (Ref. 13227). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models

Preferred temperature (Ref. 123201): 23.9 - 29.1, mean 27.5 °C (based on 1237 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 475 [166, 2,008] mg/100g; Iron = 2.51 [0.83, 5.98] mg/100g; Protein = 18.2 [16.3, 20.0] %; Omega3 = 0.0932 [, ] g/100g; Selenium = 67.1 [11.5, 307.1] μg/100g; VitaminA = 35.8 [4.4, 287.3] μg/100g; Zinc = 5.91 [2.46, 11.38] mg/100g (wet weight);
