Hypselodoris apolegma

Hypselodoris apolegma

This nudibranch is decked out in purple and yellow, complementary colors. It is crossing an orange desert. Maybe the extincct Martian oceans looked like this. The genus Hypselodoris contains many, varied nudibranchs. Apolegma usually have purple rhinophores, but for this individual these forehead-mounted smelling organs are yellow. It may be a member of a sister species.
