Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 17 - 19; Anal spines: 2; Anal soft rays: 19 - 21. Color in life unknown. Preserved specimen with vertically elongate blotch behind eye; ca. 10 bifurcate bars on body and dark spots on anterior body. Dorsal fin deeply notched; segmented caudal rays typically 13-14, middle 2-8 (typically 5-8)branched; supraorbital tentacle pinnately branched; nape cirri absent; posterior rim of anterior nostril with small cirrus (typically unbranched); upper lip margin laterally crenulate; males with occipital crest; last dorsal ray and caudal peduncle connected by membrane; body elongate, depth at anal-fin origin ca. 7.0 in SL. Maximum length, 6 cm TL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); Adults inhabit rocky shores (Ref. 90102). 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): 28.3 - 29.3, mean 28.8 °C (based on 1038 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
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).
