Hi Bill,
I would like to know if Dolabella auricularia eats the Marine Sponge Axinella sp. or Pseudoaxinella massa.
Thank you
Best Regards
Arnaud

Dear Arnaud,
Dolabella auricularia, like all Sea Hares, is a herbivore. Dolabella feeds on a variety of algae. Have a look at the Dolabella references page for some relevant literature. It is possible that a bit of sponge could be ingested during feeding, and so sponge spicules could be found in the stomach or faeces, but this is just a case of messy eating rather than a natural diet.

Your very specific question suggests you have discovered some identifiable spicules in its stomach, or a molecule linked to an axinellid sponge?
Best wishes,
Bill Rudman.
