Chee Kong has shared the identity of this cowrie on his flickr. It is Blasicrura teres, a possible new record for Singapore! He also added a link to an article on the taxonomic status of this species on the man and mollusc website. From the site, it appears identifying this cowrie is a really 'complex' issue :-)
The cowrie was found by Chay Hoon during our recent trip to Cyrene Reef. Here's her photo of it on her flickr.Here's photos of the shell, the upper side
Side viewUnderside, with the very handsome animal retracted.Wow! This is exciting!
Update (28 Jul): Thanks to comments from "Collector" on this blog, ChimCK has posted an amendment to this identification on his flickr
"Previously suspected to be Blasicrura teres and hence another possible new record in Singapore.Ah well, I'm just glad there are special animals on Cyrene, even if they are not first records!
Further reading of literature and comments from knowledgeable collectors suggest that this specimen is more likely to be Erronea walkeri walkeri.
This species has been recorded in Singapore.
Some species of Erronea have similarly looking soft parts (e.g., mantle, foot and papillae)".
Thanks to everyone for contributing to the issue. We sure learn a lot when we discuss with one another!
