[2] This species was described from two specimens, one found in a rock pool one mile south of Kalk Bay harbour and the other amongst barnacles at Dalebrook, both in False Bay, South Africa.

It is found from the Atlantic coast of the Cape Peninsula to Port Elizabeth, intertidally to at least 30 m.[3] The candy nudibranch is a vividly coloured nudibranch, having a yellow-orange body and turquoise or purple cerata with yellow tips.

Three distinct colour forms exist, two with blue cerata and yellow to orange rhinophores and another form with lilac cerata and lilac coloured rhinophores and oral tentacles.

The candy nudibranch eats the hydroid and passes its nematocysts unharmed through its digestive system to the tips of its cerata.

It is probable that the bright colours of the candy nudibranch serve to advertise to predators that it is toxic.
