Length at first maturity / Size / Weight / Age

Maturity: Lm 2.4, range 2 - ? cm Max length : 3.8 cm SHL male/unsexed; (Ref. 109255); common length : 2.5 cm SHL male/unsexed; (Ref. 109255)

Biology     Glossary (e.g. epibenthic)

Minimum depth range from Ref. 121806. Occurs throughout the Mediterranean coastal waters (Ref. 121808). Subtidal (Ref. 105316). Inhabits fine well-sorted sand (Ref. 2780) and fine muddy sands (Ref. 121806). Often buried into substrate with its proboscis protruding. Emerges at night to forage (Ref. 107005). Also found offshore (Ref. 121805). Genus is known to scavenge (Ref. 104227). Juveniles feed on detritus-rich substrate while adults are carnivores and scavengers (Ref. 107005).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

This species is a non-broadcast spawner. Life cycle does not include trocophore stage (Ref. 126039). Assumed sex reversal from male to female occurs at lengths 1.8 to 2.0 cm ShH (Ref. 107005). Also Ref. 833.
