Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 14 - 16; Anal spines: 3; Anal soft rays: 10 - 12. Distinguished by the following characteristics: brownish or dark grey body color of adults with irregular pale blotches and spots and prominent maxillary streak (capable of reversing body color pattern when under stress); juveniles mottled greenish brown, with prominent white spots on head and body, median fins with white streaks and hyaline golden pectoral fins; oblong and compressed body, depth 3.0-3.3 times in SL; head length 2.6-2.9 times in SL; convex interorbital area; enlarged serrae of preopercle at the angle, forming rounded lobe below shallow indentation on vertical limb; few small serrae on subopercle and interopercle; subequal sizes of anterior and posterior nostrils in juveniles, adults with 3 times larger posterior nostrils compared to anterior ones; lower jaws extends well in front of upper jaw (Ref. 89707).

Biology     Glossary (e.g. epibenthic)

Adults occur near the bottom in rocky areas; juveniles are found in tide pools (Ref. 89707). Two specimens collected from the Cape Verde by J. Cadenat were from a depth of '50' m (Ref. 27000). Observed to have a homing behaviour leaving the bay of Garajau on the south coast of Madeira Island in spring and returning every year in autumn (Ref. 75147).

Estimates based on models

Preferred temperature (Ref. 123201): 16.7 - 25.3, mean 19.9 °C (based on 56 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00933 (0.00429 - 0.02028), b=3.04 (2.87 - 3.21), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.3   ±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):  Moderate to high vulnerability (52 of 100).
