We are currently working on the first 'big' attempt to propose a molecular
phylogeny of the Pycnogonida or commonly called sea spiders. These are
fascinating, bizarre small arthropods, usually cryptic and not abundant.
However, they inhabit all marine habitats around the world and this is why
I am kindly asking for your collaboration.
In case you find pycnogonids in your samples, e.g. trawlings, dredging,
associated to molluscs, echinoderms, washings of algae or intertidal
samples, etc, I would enormously appreciate you could keep and preserve any
specimen in 90% Ethanol and refrigerated.
These creatures are difficult to find and not very well-known so
collaboration from marine invertebrate specialists or basically anyone
going out to the sea is very much appreciated. I can run with shipping
charges and any other costs.
I hope to hear from any of you soon, any relevant information or assistance
would be greatly appreciated and any collaboration would be acknowledged as
