Every year, a small group of harbour porpoises traverses a narrow strait from the Black Sea to the Sea of Asov, then returns again, in a natural migration cycle. Since prehistory, these Black Sea porpoises have been isolated, evolving separately from other porpoises, becoming smaller, but with larger snouts. They’re sleek and cute, with eyes and mouths that have the perpetual hint of a smile.
The UK may have to make concessions on fisheries to become part of the EU's major military build-up.
