Nembrotha rutilans feeding

Note added 4 March 2008: Following Pola et al (2008) the name N. rutilans has been replaced by Nembrotha purpureolineata [see message #21419].

Hi there,
 
We found our resident Fly Point Nembrotha "sticking out its tongue". Is it projecting its radula to eat? It was like this for at least 15 minutes and didn't move. Any ideas ?

Dear David & Leanne,
Thanks for the interesting photograph. Yes your Nembrotha is not being rude to the photographer but is sticking out its 'proboscis'-like oral tube so that the radular teeth can 'bite' its food. I presume the Nembrotha will be feeding on an ascidian or sea-squirt - either solitary or colonial - so it would be worth trying to identify where the proboscis is actually spending its time.
Best wishes,
Bill Rudman.
