External morphology

Body elongate, narrow, black or brown in colour, rear tail darker. Foot large.

Ecology

Specimens found grazing on biofouling at night over calcarean red algae or boulders, in very superficial waters.

Distribution

Atlantic Spanish coast: Canary Islands and Strait of Gibraltar ( Cervera et al. 2004) and Mediterranean Spanish coast: Catalonia (this study).

Remarks

This species is rarely observed and very small. Easily distinguishable from other Runcina species by its absence of spots and white marks and its uniform black colour ( Quatrefages 1844).
