Hexabranchus sanguineus and purple ink?

July 7, 2001
From: Friedrich Huneke

Hi!
When I was looking for a photo of a "Purple producing snail", murex etc, I was offered photos of a Hexabranchus sanguineus, but I think they do not produce the red purpur colour used anciently for expensive, royal dress. May you help me?
Thanks

Dear Friedrich,
Hexabranchus certainly doesn't produce the royal purple dye. I have discussed the origin of this 'Tyrian Purple' in a couple of messages [message 1, message 2]. Have a look at them for some background information. Sea Hares also produce a purple ink but it is not used in producing dyes.
Best wishes,
Bill Rudman
