Thuridilla carlsoni from Sulawesi

Dear Bill

Not a lot of posting on the site so I thought I'd share this picture. It was taken at Budo Point dive site off Sulawesi on a night dive.

Locality: Dive Site - Budo Point, 45 ft, Sulawesi, Indonesia, Celebes Sea, 21 October 2006, Fringing reef. Length: 2 cm. Photographer: Mike Krampf.

Not to diverge to far, can you recommend a website that helps with identifying flatworms?

Dear Mike,
Thanks for this record. I've added a close-up alongside to draw attention to the green patches on the parapodia. They are not pigment spots but 'gardens' of chloroplasts obtained from the green algae this animal feeds on. Have a look on the solar-powered slugs for back ground information.

Have a look at the flatworm Fact Sheet for a link to a good page.

Best wishes,
Bill Rudman
