Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 5 - 100 m (Ref. 2739). Subtropical; 45°N - 12°N, 19°W - 36°E
Eastern Atlantic: Portugal and the Canary Islands, south to Senegal. Also throughout the western and the eastern Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm 7.8  range ? - ? cm
Max length : 25.0 cm TL male/unsexed; (Ref. 2739); common length : 15.0 cm TL male/unsexed; (Ref. 26999)
Found over seagrass, sand, mud and rocks (Ref. 2739). Carnivorous, decapods dominate the diet. Adapts well in an aquarium (Ref. 12382). A synchronous hermaphrodite (Ref. 56921).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Manifests synchronous hermaphroditism, particularly, differentiation of the ovary is earlier than that of the testis (Ref. 56921).
