Concerning message #23426:

Dear Bill,
We have had a one day visitation from these handsome (big) beasts. I don't see any records from Thailand.

Locality: Chaloklum Bay, Koh Phangan, 4-5 metres, Suratthani, Thailand, Gulf of Thailand., 14 May 2010, Sandy with algal growth. Length: 15-20 cm. Photographer: Nick Chapman.

Best wishes,
Nick.

Dear Nick,

From your middle photo showing a large mound of pinkish egg strings [see close-up] I suspect the visitation of these Bursatella leachii that you describe is part of the population's life cycle [see mating chains and mass mortality Fact Sheets]. There seem to be at least 3, possibly 4, animals clustered together. With Sea Hares, a large mass of egg ribbons like this can be produced by multiple animals over a few days.

Best wishes,
Bill Rudman
