Hypselodoris kanga

Hypselodoris kanga is a species of sea slug or dorid nudibranch, a marine gastropod mollusk in the family Chromodorididae.

Distribution
This nudibranch was described from Kunduchi, Dar es Salaam, Tanzania. It was previously reported throughout the Indian Ocean and West Pacific Ocean. Specimens from the Pacific Ocean are now thought to be other species, including Hypselodoris confetti and Hypselodoris roo. It has been recorded from Mozambique.
