ICZN opinion 200 ruled that Tethys fimbria is a valid name and Tethys leporina Linnaeus, 1758 is a synonym.[2]DistributionThe distribution of Tethys fimbria includes the Mediterranean Sea and the east coast of the Atlantic Ocean from Portugal in the north, to the Gulf of Guinea in the south.[5] DescriptionThe length of the body of Tethys fimbria can reach up to {{convert|30|cm|0|abbr=on}}.[5] Tethys fimbria is translucent, but it has dark spots on its cerata.[5] It has a broad oral hood in the frontal part of its body.[5] Rhinophores are small.[5] Tethys fimbria has no radula as is the case in all members of the family Tethydidae.[5] EcologyThe habitat of Tethys fimbria is seas which have sand or mud on the bottom, in depths from 20 to 150 m.[3] Tethys fimbria captures and feeds on small crustaceans.[3] It uses its broad hood for catching them.[3]The cerata can be self-amputated (autotomy) as a defence mechanism when the slug is in danger.[3] Within the mantle large amounts of prostaglandins are produced.[4] Subsequently the prostoglandins are moved to the cerata.[4] The biosynthesis of prostgandins has been studied by Marzo et al. (1991).[4] References1. ^1 Linnaeus C. (1758). Systema Naturae, ed. 10, 653; 1767, ed. 12, page 1089. 2. ^1 "Tethys fimbria Linné 1767 ".
