Biology     Glossary (e.g. epibenthic)

Lives between rocks, boulder strewn areas and walls. Lurks in holes, crevices and dark recesses during the day; forage in the open at night. Constantly opens and closes its mouth-an action required for respiration-not a threat (Ref. 5227 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 22.1 - 28.6, mean 26.7 °C (based on 36 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5002   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00050 (0.00025 - 0.00101), b=3.26 (3.10 - 3.42), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  4.5   ±0.8 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  High vulnerability (56 of 100). Nutrients (Ref. 124155 ):  Calcium = 30.8 [17.1, 47.2] mg/100g; Iron = 0.499 [0.301, 0.930] mg/100g; Protein = 18.6 [16.4, 21.2] %; Omega3 = 0.0989 [, ] g/100g; Selenium = 41.1 [22.6, 82.7] μg/100g; VitaminA = 93.4 [28.1, 292.4] μg/100g; Zinc = 0.872 [0.615, 1.203] mg/100g (wet weight);
