Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 5 - 6; Anal spines: 0; Anal soft rays: 5 - 7. Uniform red brown to yellowish with variable narrow bands along the head, level with the eye on the dorsal surface of the body, often breaking up into spots on the sides. Fins transparent. Distinguished from other clingfishes by its small size with a slender body tapering behind the head and the pointed fleshy tip on the upper jaw that overhangs the lower jaw.

Biology     Glossary (e.g. epibenthic)

Found amongst weed at low tide, and on brown algae in the subtidal zone. Appears to be restricted to algal species with strap-like fronds. Feeds mainly on harpacticoid copepods.

Estimates based on models

Preferred temperature (Ref. 123201): 13.9 - 17.8, mean 15.9 °C (based on 67 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00398 (0.00190 - 0.00835), b=3.13 (2.94 - 3.32), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (tmax=4).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
