Where
seen? This tiny slug is sometimes seen on Big
coin green seaweeds (Halimeda sp.). Several slugs may be
seen on one clump of seaweed.
Features:
A tiny
well camouflaged slug 0.5-1.5cm. Oval, flat almost featureless body,
with tiny tentacles at the head. The body is transparent or exactly
the same colour as the seaweed that it is found on. The seaweed concentrates
toxins in its youngest parts. Studies show that the slugs not only
prefer to feed on these toxic parts of the seaweed, but also use the
toxins to protect themselves and their eggs. |
