Geographic Distribution

Common and widespread in Indo-Pacific.

Identification

Chromodoris with similar colouring to other Chromodoris species. Retractable simple gills and lamellate rhinophores. May be seen with yellow rhinophores and gills or pink. The blue colour on the dorsum may be dark blue through to very pale blue.

General Notes

The variation of colours on dorsum and gills/rhinophores meant that it was thought that Chromodoris boucheti found in the Indian Ocean was a different species - but recent research has shown that they are the same species.
