Description

A small heterobranch sea slug from Antarctic waters. The mantle is conspicuously wider than the foot and bears numerous irregularly arranged conical papillae of mixed sizes. The mantle margin spreads wing-like in a wavy fashion, with smaller papillae scattered along its edge. The body is translucent to opaque white, with concentrated white pigment often on the mantle margins and at the tips of the papillae.

Distribution

The original description (Vayssière, 1906) was based on specimens collected during the French Antarctic Expedition led by Dr. Jean-Baptiste Charcot (Expédition Antarctique du Dr Charcot). Distributed in Antarctic waters.

Etymology

The specific epithet granulosa is the Latin feminine of granulosus, "granular", referring to the granular conical papillae scattered over the entire mantle.

Remarks

The original combination was Charcotia granulosa Vayssière, 1906, in a genus named after Dr. Charcot — the French physician and polar explorer (1867–1936) who led two expeditions aboard the "Français" and "Pourquoi Pas?", from which many marine organisms were newly described.
