Description of the first cryptobranch onchidoridid Onchimira cavifera gen. et sp. nov., and of three new species of the genera Adalaria Bergh, 1879 and Onchidoris Blainville, 1816 (Nudibranchia: Onchidorididae) from Kamchatka waters
The opisthobranch fauna of the SE Kamchatka peninsula (NW Pacific, Russia) has been intensively investigated for the first time resulting in 21 species found, and six new records for Kamchatka. A unique onchidoridid species with a well defined, closeable gill pocket into which gills can be fully ret...
