Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 20; Radios blandos dorsales (total) : 4; Espinas anales: 9; Radios blandos anales: 4.
Body shape (shape guide): elongated.
Facultative air-breathing (Ref. 126274); Are residents of intertidal zone with homing behavior (Ref. 32612) found in pools with rocks or boulders. May leave tide pools if aquatic conditions become inhospitable (Ref. 31184). Feed mostly on invertebrates, particularly crustaceans and mollusks. They breathe air when out of water (Ref. 31184) and swim with an eel-like motion (Ref. 9003). Eggs are guarded by the male parent (Ref. 205).
Life cycle and mating behavior
Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva
Nests are constructed beneath boulders where the dense gelatinous cluster of about 10,000 eggs are deposited. The male stands guard and seals the nest from the inside by blocking the entrance with small stones and mud. Eggs hatch after about ten days into planktonic larvae (Ref. 9003).
