Hi Bill,
Concerning your question about the limits of the Western Mediterranean, this a not an easy matter. This may depend of the animal group, but in general the area of the Strait of Gibraltar seems to have a higher Atlantic composition or influence, although you can find also Mediterranean species. There are few groups in which this subject has been studied (it seems to me Sponges, Bryozoans and Tunicates). For opisthobranchs, I hope to include a chapter with this matter in a paper that I'm preparing together other Spanish and Portuguese colleagues. At the moment, I'd rather wait until our analysis is omplete before saying anything.

Nevertheless, the coasts from Granada to Almeria can be considered mainly to have a Mediterranean influence.
Regards.
Lucas.
