Hello Bill,

I was in Saudi Arabia last week. I saw there on Dohra island two giant Halgerda willeyi. Between 25 and 30 cm.

Dear Gert,

Thanks for this record. At about 30 cm these are definitely quite large animals. I don't know if you realised, but your photo has captured these animals feeding. If you look at the dark grey sphere behind them you will see a great cavity which has been eaten out by one or both of these nudibranchs. We know very little about the biology of most nudibranchs so a piece of information like this is very valuable. I can't identify the sponge off-hand but if sometime in the future a researcher is investigating the food of this genus it will be a useful clue.

Best wishes,
Bill Rudman
