Found feeding on Hydroids growing on the thalli of Dictyopteris sp. Brown Algae.
 
They store nematocysts from their hydroid prey in cnidosacs spread all over the dorsal surface of their body.
They hold their fan like cerata up like cups as they travel but will spread them out and lay them down like the fingers of a hand when resting.
