Ekologin hos Sepiola rondeletii

Main Ref.	Roper, C.F.E., M.J. Sweeney and C.E. Nauen, 1984
Anmärkningar	An epibenthic or mesobenthic species found on sandy and muddy substrates, commonly on Posidonia seagrass beds (Refs. 1695, 123761). Recorded from very shallow waters down to around 450 m. Females over 3 cm mantle length are mature. Mating takes place when males grasp the female's 'neck' region, and spermatophores are placed in the female's bursa copulatrix. In the western Mediterranean, spawning season extends from March to November; longevity estimated at 18 months. (Ref. 1695). Feeds on crustaceans and small fishes (Refs. 275, 1695).
