The animal is a translucent brownish colour with a pattern of opaque white lines and patches, and scattered irregularly shaped brown spots, all of similar size. In some animals there is an irregular white line running from between the rhinophoes back to the gills where its splits to form a ring around the gills and then joins again posteriorly. The white pigmnetation can also fome short longitudinal streaks elsewhere on the mantle, and in some specimens the median line is not clear.
There are three pairs of long papillae along the edge of the mantle. These are slightly swollen at the tips which give rise to a number of elongate and branching filaments. Around the anterior end of the mantle there are five or six similar papillae, and along the outer edge of the rhinophore sheath there are two or three more. Scattered over the mantle and the sides of the body are smaller conical papillae with an unbranched terminal filament. These filaments give the body and the papillae a hairy appearance which gives the species is its name [peludo = hairy in Spanish].

Kaloplocamus peludo from Heron Island
February 28, 2007
From: Julie Marshall
Dear Bill,
With reference to Bill Bolland's message about the new species Kaloplocamus peludo I have found four specimens of this species at Heron Island [Great Barrier Reef]. They were found under dead coral slabs at the reef crest at low tide or on bryozoans attached to grids covering saltwater intake pipes. Attached is a photo of one of them which originally appeared in the book by Richard Willan and myself on the Nudibranchs of Heron Island as Kaloplocamus sp. 1.
Locality: Heron Island, 1 m., Queensland, Australia, Pacific, November 1998, Intertidal. Length: 10 mm. Photographer: Julie Marshall.
Best wishes,

Thanks Julie,
I have added a few close-ups of part of your animal to show the 'hairy' nature of the lateral papillae
Best wishes,
