Biology     Glossary (e.g. epibenthic)

Lives in rocky, boulder strewn areas and walls. Lurks in holes, crevices and dark recesses. Constantly opens and closes its mouth, an action required for respiration, not a threat (Ref. 5227 ).

Estimates based on models

Preferred temperature (Ref. 123201 ): 23.1 - 29.1, mean 27.3 °C (based on 229 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5010   [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 ):  4.0   ±0.6 se; based on size and trophs of closest relatives Resilience (Ref. 120179 ):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.). Fishing Vulnerability (Ref. 59153 ):  High to very high vulnerability (72 of 100). Nutrients (Ref. 124155 ):  Calcium = 25.6 [13.5, 43.4] mg/100g; Iron = 0.41 [0.24, 0.91] mg/100g; Protein = 18.8 [16.6, 21.4] %; Omega3 = 0.0915 [, ] g/100g; Selenium = 41.9 [22.3, 84.5] μg/100g; VitaminA = 54.2 [15.3, 176.3] μg/100g; Zinc = 0.891 [0.627, 1.247] mg/100g (wet weight);
