Nembrotha rutilans from Bali?

August 29, 2003
From: Jukka-Pekka Salmenkaita


Note added 4 March 2008: Following Pola et al (2008) the name N. rutilans has been replaced by Nembrotha purpureolineata [see message #21419].

Dear Bill,
I photographed this specimen in Biaha, Candidasa, Bali, Indonesia in 25th July 2002. Is it Nembrotha rutilans? It could have been eating that small bluish ascidian(?).

Best regards,
Jukka-Pekka

Dear Jukka-Pekka,
Yes this is N. rutilans. I am pretty sure it is eating one of the translucent white ascidians which seem quite abundant in your photo. The bluish thing you can see is the slug's oral tube which everts out of the mouth during feeding. At the end of it is the slug's radular teeth which bite off chunks of the ascidian and drag them into its mouth.
Best wishes,
Bill Rudman
