Short description Morfología | Morfometría

Radios blandos dorsales (total): 7. Black spot on each side of the caudal peduncle. Males with a second similar spot behind each pectoral fin (Ref. 35388); eyes situated laterally; fully scaled; possess functioning suckers; caudal fins slightly notched (Ref. 92840).

Biología     Glosario (por ej. epibenthic)

Suprabenthic (Ref. 92840). Found inshore in groups around over-grown structures and among Laminaria or Zostera beds. Adults feed on small crustaceans (copepods, amphipods, mysids) and chaetognaths (Ref. 4696). Eggs are about 1 mm long, pear-shaped, and adhere to seagrass or weeds; hatch in 10 days (Ref. 4696). Pelagic larvae hatch at 2.5 mm length (Ref. 35388).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Repeat spawners (Ref. 4696). Eggs are found inside hollow Sacchoriza holdfasts or other smooth substrates (Ref. 4696). Nests of care-giving males contain eggs from several females (Ref. 115238).
