Concerning message #20254:

Hi Bill,

Thanks! I did not realise there are actually 2 animals since I thought they mate like other nudibranchs (facing oppasite direction).

Can I say it is a rare species or uncommon species?

Thanks again,
Leena

Dear Leena,

It's a bit hard using terms like 'rare' and 'uncommon'. If we don't know where an animal lives then we should say 'rarely found' as the species may be extremely common in their normal habitat.  As you'll see if you read the messages on various species of Chelidonura on the Forum, a species can be found in great abundance for a short period and then be absent so it goes from being abundant to rare in a few weeks. So if I say Chelidonura pallida appears to be uncommon what I am really saying is we don't have many records of it which might mean its rare or it might mean we don't know where it lives. 

Best wishes,
Bill Rudman
