Painted Balloon Aeolis

Eubranchus tricolor

• Group: Nudibranch

This aeolid sea slug wears slender finger like outgrowths along its back, often banded in bright colours, which double as gills and as defence. It feeds on a close relative within its own genus, grazing among the hydroid growth where both are found.
