Hello

I observed this Placida dendritica on a green leafy sea plant. Can you confirm if this is that species?

Locality: Anilao, 15 Meters, Philippines, Philippines, 05 October 2007, Sandy - muck diving. Length: 0.8 cm. Photographer: Jeffrey C. de Guzman.

Dear Jeff,
This is a sacoglossan, but not a species of Placida. In the lower photo you can see that the two large back eyes are close together between the rhinophores. This is only found in the genus Costasiella, and you animal is one we are calling Costasiella sp. 3 at present.

Best wishes,
Bill Rudman
