Big purple-footed nudibranch from Singapore

June 28, 2006
From: Ron Yeo

Hi Bill,

Found this big fat nudibranch on an islet which is only exposed during very low tides. The islet is located near an island called Pulau Tekong in Singapore.

Locality: Beting Bronok, Singapore, Singapore, South China Sea, 25 June 2006, Intertidal. Length: 15 cm. Photographer: Ron Yeo.

Would really appreciate it if you can assist to identify it.

Thanks,
Ron Yeo

Dear Ron,

The dark purple foot and underside of mantle, and the rows of dark brown spots on the upper side of the mantle, are all good indications of Atagema spongiosa. I have never found two very large animals together like this, but as you no doubt noticed, they are very well camouflaged in their natural environment, so are probably often overlooked.

Best wishes,
Bill Rudman
