Type locality: Norway . See: Tortonese (1965: 104–105 , fig. 45); Picton (1993: 82–83) . Occurrence: Mediterranean Sea and Northeast Atlantic; from Scandinavian arctic waters south along European coasts ( Tortonese 1965 ) to the Azores ( Wirtz 2009 ) and Canaries ( Pérez-Ruzafa et al . 1992a ). Depth: 0–173 m , mostly between the first few meters and 50 m deep ( Pérez-Ruzafa et al . 1992a ); also found in tide-pools ( AZO ; Wirtz 2009 ). Habitat: soft sediments buried in muddy sand or gravel, and amongst Zostera and Caulerpa and in sandy tide pools ( Picton 1993 , Pérez-Ruzafa et al . 1992a ). Larval stage: Planktotrophic, hermaphroditic ( Mortensen 1927 a , McEdward & Miner 2001). Remarks: recently, Wirtz (2009) discovered small specimens belonging to Leptosynapta inhaerens in tidepools in Faial Island, turning the archipelago to the westernmost limit for this species.
