Caliphylla mediterranea A. Costa, 1869
3mm Qajjenza <1m depth 18/5/94
Small sized sacoglossan found in shallow water (>1m depth) in collections of Cladophora sp. The body colour is a pale greenish-white with green markings and red spots. The large transparent leaf-like cerata are dotted all over with red spots but white spots are present near the edges. The green digestive gland can be seen in each ceras. Rhinophores are partially folded and bifid. Foot is transparent with several red spots without transverse separation into two areas.
Size: 3-9mm.

Specific characteristics: A very rare species, which is difficult to find in the field. The green internal colour in the cerata and short foot tentacles separate this species from Polybranchia and the lack of a transverse line across the foot is the distinguishing features of this species in relation to Cyerce.
