I guess the real question is why are there not more non-boreal species
that occur on both sides of the Atlantic?  If a few species such as
Nodipecten nodosus managed to cross the pond in Pleistocene times, why
are there not more of them?  What a great topic for a PhD thesis!!!

Drying out, but with a still-submerged pier on the river,
