This chromodorid is not well-known and seldom illustrated, probably because its lives outside the "centres" of chromodorid diversity - the Indo-West Pacific, Caribbean, and Pacific east coast. Growing to over 18cm long it is one of the largest chromodorids. Hypselodoris zebra deserves an important place in "chromodorid history' because it was the species which attracted Crozier's attention and let to his early discussions and studies on the apparent immunity chromodorids have from fish predation.
