Chelidonura tsurugensis

Family: Aglajidae


Described from Japan, it is possibly widely distributed in the tropical West Pacific and also the Indian Ocean.

This small species, 15-20mm long alive, appears to be widely distributed in the western Pacific, being quite common on sand flats on the Great Barrier Reef. It has also been recently reported from Western Australia (Wells & Bryce, 1993. Sea Slugs of Western Australia).

It is also possible that Chelidonura sandrana from the western Indian Ocean, is a colour form, but Wells & Bryce suggest that both species? forms? occur in Western Australia. I have discussed this more fully under C. sandrana.
