Asteronotus cespitosus from Singapore

March 22, 2010
From: Ron Yeo

Dear Bill,

I found this huge nudibranch, and initially thought it be be a Dendrodoris carbunculosa. However, it has much simpler tubercles and has several long ridges nearer to the sides of the animal forming broken rings around it. The underside looks very different too. Have you come across something like this before?

Locality: Pulau Semakau, Singapore, Straits of Singapore, 21 March 2010, Intertidal. Length: 20cm. Photographer: Ron Yeo.

Thanks.

regards,
Ron Yeo

Dear Ron,

This is Asteronotus cespitosus. It can grow quite a bit larger than your animal. I think there is a record on the Forum of a 40 cm long individual.

Best wishes,
Bill Rudman
