Bill,

This is another photo taken at Bundegi Reef in Exmouth, Western Australia. I am having problems identifying this one, can you help me out?

Dear Drew,
This is Moridilla brockii, one of a group of aeolids which appear quite aggressive when disturbed, 'bristling' their cerata in a show of bravado. as you'll see at the top of the page, in Moridilla the innnermost cerata in each row are much longer than the others, lying coiled like a spring, only uncoiling when the animal feels threatened. Have a look at the pages on the aeolid cnidosac and on defensive coloration in nudibranchs for information on aeolid defence methods.

Best wishes,
Bill Rudman.
