Glossodoris paladentatus from Vanuatu

November 22, 1999
From: Vinka Stenhouse

Dear Bill,

Can you identify this one from Espiritu Santo Is., Vanuatu (1998) please? It was from 18 metre depth. Crawling over sponge in a current prone area. 20 mm long.

Yours sincerely,

Vinka Stenhouse.

Dear Vinka,
At first sight it looks like it is Glossodoris atromarginata, but there are a number of similarly coloured species of Glossodoris which are best identified by looking at their internal anatomy. This is not very convenient for field observers.

I am pretty sure your animal is a species I named Glossodoris paladentatus which has most unusually shaped radular teeth. Externally, the brown smudged marks on the mantle are quite characteristic.

I think this is the first time it has been recorded since it was named.

Another interesting find,
Bill Rudman.
