Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 1 - 200 m (Ref. 105998). Subtropical, preferred 20°C (Ref. 107945); 45°N - 30°N, 10°W - 36°E
Eastern Atlantic and the Mediterranean: from Portugal to central Morocco in the Atlantic, and east to Lebanon. Introduced in Atlantic Spain.
Length at first maturity / Size / Weight / Age
Maturity: Lm 5.6, range 4 - ? cm Max length : 10.8 cm ShL male/unsexed; (Ref. 127250); max. published weight: 79.70 g (Ref. 127250)
Has high economic value since ancient times because it is used to produce a purple dye (Refs. 78459, 78460 and 78461). Carnivorous and feeds on bivalves and other gastropods (Ref. 2532). GSI of females read off from Ref. 114300 (p. 32, Fig. 6B) using WebPlotDigitizer. Annual spawning was from April to July with peak from May to June (Ref. 114300).
Showed an annual reproductive cycle in the Catalan coast. The reproductive cycle had two peaks (April and June -July) but the first one seems to be less important because the number of immature females is higher than the mature ones.
