Cuthona annandalei   Eliot,  1910 (Sea Slug)
Organism information awaits expert curation
Class: Gastropoda

Size: 7-8 cm long, 5-7 cm broad.

The head is extended into a roundish disk bearing two nearly equal pairs of simple tentacles with no trace of proliferation. The eyes are small, but distinct and black. The foot is not angulate, but like the head, is expanded into a disk. The tail is short and rounded.

The purplish diverticula of the liver are visible through the skin. They communicate with a distinct purple hepatic track in the body cavity posterior to the stomach. The branches of the track are simple and clear, as in Tergipes. The cerata are disposed in two divisions. The first consists of four groups lying immediately behind the rhinophores and supplied from right and left diverticula of the stomach. Then comes a gap, and behind it are 6-7 rows of cerata, the rows on the right and left hand sides not being accurately opposite to one another. There are 5-6 cerata in each row, and all are supplied from the posterior diverticulum of the stomach. The cerata are cylindrical and moderately tapering. The jaw is yellowish and bears a single row of distinct denticles, which have blunt, but not square, tips.
