Anyone know what species of sea cucumber this is? Shot at Koh Ta Chai in Andaman Sea, Thailand.

First impression is that it's an oddly colored Bohadschia argus but with cukes first impressions are often wrong. Why don't you contact the IP holothurioid expert Gustav Paulay? \http://www.flmnh.ufl.edu/malacology/paulay.htm

Thanks Leslie. I wondered about an oddly coloured B. argus as well. I've sent Dr Paulay an email.

Dr Paulay has kindly identified it as Actinopyga caerulea. Thanks again
