Dendronotus sp. from Indonesia

From: Wolfgang Kraemer

Dear Bill,

Here is a photo of what I assume a Dendronotus. Can you please help in the identification?

Locality: South end of Siladen Island, Manado, 15 m, Indonesia, Celebes Sea, 6. September 2007, Wall. Length: approx. 25 mm. Photographer: Wolfgang Kraemer.

Thanks and regards,

Dear Wolfgang,

I agree that this is the 'tropical' Dendronotus I am calling Dendronotus sp. 1. Most animals we have photos of don't have the strong orange coloration seen in your animal, but in external anatomy I can't see any real differences, and even the 'whitest' example we have still has orange rhinophores.

Best wishes,
Bill Rudman
