Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 12 - 13; Mjukstrålar i ryggfenan (totalt) : 19 - 21; Taggstrålar i analfenan: 2; Mjukstrålar i analfenan: 21 - 23. Males darkly dusky with 5-6 pairs of bands on body and pale stripes on dorsal fin; develop a crest. Females paler in color, bands broken into spots posteriorly, dorsal fin spotted (Ref. 4404).
Facultative air-breathing (Ref. 126274); Intertidal (Ref. 31184, 48636). Adults are common in areas with large rubble pieces which are often used to built breakwaters or to support jetty-pylons (Ref. 48636). They hide in cracks or holes when not feeding. They jump out of the water in energetic skippings to another pool when pursued (Ref. 2158, 48636). May remain out of water under rocks or seaweeds (Ref. 31184). They breathe air when out of water (Ref. 31184). Feeds on filamentous algae (Ref. 89972). 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).
