Spanish Dancer - Hexabranchus sanguineus

May 18, 2000
From: Brandon

I am doing a report on the nudibranch (specifically the Spanish Dancer) and the only information I cannot find is at what age do they reach sexual maturity. I know their life span is not long, but I have not been able to find how "old" they are when they can reproduce. Is that information available?

Dear Brandon,
There was a paper some years ago by by Francis (1980) on aspects of the life history of Hexabranchus. I am not 100% certain, but I think he had some information on how old they were when they began egg laying.

It is in in The Veliger. I'm afraid I am working from home for a few days and don't have the paper available. Have a look at the page of references on Hexabranchus biology for a citation.

Best wishes,
Bill Rudman.
