Re: Ceratosoma miamirana and possible food

Dear Bill,

Thanks for your comments. I suspected the sponge I found the C. miamirana on might be a prey item since it was an identical shade of cinnamon brown. I looked very closely, but could not see any missing sponge under or around the slug. Is it possible it was eating the slime off the sponge? I went back to the sponge a couple of hours later, but the slug was gone.

Thanks for all you have taught me about sea slugs.

Best regards,
Mary Jane

Dear Mary Jane,
I'm afraid sometimes its difficult to get from the 'hunch' stage to some real evidence.
I'm sure that mucus would not sustain an animal although at times people have suggested it as a possible food. While in some cases it is easy to see where a sponge has been partially eaten, these leathery sponges need to be quite seriously bitten before the damage is noticeable. I mentioned the possibility that the sponge was a food item because I am always optimistic, but my main aim was to alert you and other readers to the potential we all have to make an interesting discovery.

I'm glad you are enjoying the Forum,
best wishes,
Bill Rudman.
