seen? This well camouflaged slug is sometimes seen among green seaweeds on our Northern and Southern shores.
3cm. It has a green shell and four long 'fingers' sticking out of
the sides of its body that look like tendrils of a seaweed. These
tendrils can be 'rolled up', making the slug very difficult to see
among round seagrape seaweeds, for example.
The tendrils can also be unrolled. This may be done to deter predators.
The tendrils can also be dropped off (autotomized) whereupon the tendril
continues to wriggle and thus distract the predator.

does it eat? Reports find this slug often among Oval
sea grape seaweeds (Caulerpa racemosa). The tendrils
may also help the slug obtain food from photosynthesis. Like
other sacoglossans, this slug retains in its body, the chloroplasts
obtained from its seaweed food.
