Bohadschia graffei as mimic of Phyllidia varicosa

October 17, 2003
From: Rosalind Day

Dear Bill
Having now completed my investigation into the ecology and feeding behaviour of this species, I thought I should share some information about its identification. It turns out that the species Bohadschia graffei was reclassified in 1984 to Pearsonothuria graffei due to differences from other Bohadschia species in terms of spicule morphology.
I still hope to continue my studies and have uncovered much information about its ecology, feeding behaviour and possible sensory activity if any of your readers were to make further enquiries.
I understand that this is only an off shoot from the real interest in sea slugs, but hope it may be of interest.

Dear Rosalind,
Thanks for keeping in touch. Name changes like this are good to know as often only the experts in a field know about while the rest of us continue to use out-dated names. I presume the same often happens when non-experts write about nudibranchs. A reference to the name change would be nice to include
