We found 2, maybe three, Rissos about halfway between Grassholm and Skomer this afternoon.
One was a really very large male, almost white. The other (or other two? Really hard to tell) were smaller and dark grey. They were not close together like Commons, but separated by 50-100m.
They were not interested in playing with us, but were moving fast, breaking the surface in a very dynamic way: lots of spray and splashing, before swimming underwater for 100m or more, and then resurfacing.
