Eubranchus cingulatus

(Alder & Hancock, 1847)

This slender and delicate species may reach 29 mm in length, with a grey-white body, bearing superficial olive-green or brown blotches. The cerata are arranged in up to 10 rows, each containing up to 13 (rarely 18) cerata in each half-row. They are long, finger-like and only slightly inflated, having a white subterminal band and 2-3 interrupted olive-green or brown bands lower down. Characteristically the hepatic contents of the cerata are white or pale yellow, and the olive coloration on the back is especially strongly developed between the bases of the cerata. The cerata may pucker when contracted, but are not normally tuberculated (contrary to Eubranchus doriae ). The tentacles exhibit a white tip and a conspicuous olive band (E. cingulatus-drawing).

The diet appears to be the hydroid Kirchenpaueria pinnata.

Records of this species are difficult to disentangle from those of Eubranchus doriae ; there has been much confusion between the two species (Distr. E. cingulatus).
