  • Actaeonia corrugata Alder & Hancock, 1848
  • Actaeonia senestra Quatrefages, 1844
  • Cenia cocksi Alder & Hancock, 1848
  • Limapontia cornuta Giard, 1873

The slug-like body may reach 6 mm in length, with the body coloured marbled olive-brown to black with paler extremities (the short tail and the head tentacles). It could have a slightly wrinkled dorsum. The head bears a pair of finger-like tentacles, characteristic of L. senestra and absent in other species of Limapontia. Those tentacles may be absent in juvenile specimens (smaller than 2 mm). The anal and renal openings are located in the midline of the body, at about two thirds of the body length from the head.

It is commonly found feeding on filamentous algae of the genus Cladophora and Acrosiphonia. It may share habitat with Limapontia capitata.


  • Limapontia, from Greek “Limax”, slug + “pontos”, of the sea.
  • Senestra, probably from old French “senestre”, from Latin “sinistra”, means left, perverse, weird, bad, adverse, hostile.

From Orkney and Norway down to French Atlantic coast and North of Spain. Widespread around Britain and Ireland.
