Two colour forms of Lomanotus genei

Dear Bill

Thank you for your information on Pleurobranchus membranaceus [message #19294 ].

I thought you might be interested in these images of Lomanotus genei. Although they were taken over 18 months ago I thought they might be worth sending as I believe the find was quite unusual. Originally there appeared to be only the red colour form but when turning over the hydroid it was feeding on the white form was revealed. I note there is another record of two colour forms [#17144 ].

Locality: Start Point, GPS Position: 50 13.391 N, 03 38.170 W, 15 metres, South Devon, England, UK, English Channel, 18 June 2005, Gently sloping seabed of gravel, sand and cobbles with rocky outcrops. Length: 60 mm. Photographer: Karen Williams.

Dear Karen,

This is a good find. The white one was well hidden behind the pink one. I have included a close-up of the head region of the pink one to show the rhinophores sheath [at bottom of photo] and some of the sinuous foldiing of the edge of the mantle and the attached 'cerata'

Best wishes,
Bill Rudman
