Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 12; Raggi dorsali molli (totale) : 16 - 18; Spine anali: 2; Raggi anali molli: 17 - 18. Gill opening wide, membranes broadly united and free from isthmus. Jaws with immovable teeth and a pair of canines posteriorly. Supraorbital cirrus present, longer in male. Body color extremely variable.
Facultative air-breathing in the genus (Ref. 126274); Adults are common in rocky shore areas. They feed on algae and detritus (Ref. 9137). Attain less than 9 cm TL. Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref.
123201): 17.4 - 27.4, mean 22.6 °C (based on 256 cells).
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01072 (0.00457 - 0.02514), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
