Porpoise

I agree, these are porpoise, excellent description. These are the commonest species seen from land.

Wow its great to get a photo

Wow its great to get a photo of them I seem to find that they frequently disappear far too quickly, in the summer I was out plankton sampling between penzance and lands end as part of a basking shark survey when a group of three porpoises where feeding in the area circled the boat I was gutted not to have my camera that day!!

Porpoise in Cornwall

Porpoise seem to be fairly regular along the Cornish coast and I find them the most often encountered of the sea mammals here, after Grey Seals of course.

Abundance

Plenty in the Irish Sea too, all the year round but with bigger concentrations in late summer and autumn.

I think the NBN map greatly under-represents them as it is not drawing on all available databases (which presumably have to be offered for use).
