This common species of nudibranch from the family Dorididae is seen across multiple sites in the harbour and out on the exposed reefs in Sydney. It has yellow/orange body and distinctive black spots. It is a fairly un-researched species of sea slug. There is little information published about this species and there is still debate about its classification, with some scientists naming it Jorunna sp. 2, Jorunna sp. 3, Jorunna parva and Jorunna pardus. It is from the family Dorididae.
