Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 5 - 6; Épines anales: 0; Rayons mous anaux: 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.
Body shape (shape guide): elongated.
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.
