Hancockia sp. (undescribed) I am not aware of a single described species of Hancockia in the Indo-Pacific. With this new specimen we are up to four undescribed species in - Indo-Pacific Nudibranchs and Sea Slugs. A member of the Dendronotina, Hancockia are characterized by pulpit-like rhinophores, with a lobate sheath and a tapering club with a rounded end. Jim's critter here certainly matches that. Like Hancockia californica , from the west coast of the US, the lateral appendages (pseudo-cerata) are palmate shaped. This pretty little gem is quite distinctive with its white spotted frontal appendages, white marginal line on the foot and red body specks. A tinge of purple is seen at the tip of the lateral appendages and the tips of the rhinophoral sheath. Great find Jim - and you are correct - it will be in our next edition. Thanks |

Jim has been a solid supporter of the Slug Site since day one. His countless contributions put him near the top of the list of photographers who have greatly expanded our knowledge of sea slugs. There are a lot of kids in the formative stage of their education who are getting their first introduction to our sea slug friends via the great photographs Jim and other contributors have made to the site. My hat is off to Jim for making this presentation possible!
