Grootte / Gewicht / Leeftijd
Maturity: Lm ? range ? - ? cm
Max length : 25.0 cm SL mannelijk / geslacht onbekend; (Ref. 4693); max. gerapporteerde leeftijd: 5 Jaren (Ref. 72462)
Ribbon - shaped body with 9 - 13 eye spots along the base of the dorsal fin (Ref. 35388).
Facultative air-breathing (Ref. 126274); Occurs in shallow waters (seashore, tide pools), but descends (especially in winter) to 100 m or more. May remain out of water under rocks or seaweeds (Ref. 31184). Feeds on small crustaceans, polychaetes, mollusks and fish eggs. The eggs are laid on the sea bed in a large clump, which is closely guarded until hatched (Ref. 9900). Breathes air when out of water (Ref. 31184). Spawning occur in November - January . Female lays 80-200 eggs in a large ball under a stone or in an empty bivalve shell (Ref. 35388).
Male and female coil around the egg ball (Ref. 58332).
