Apparently H. pallidus gets larger but they didn't get any this time. I got samples of most of the NE Atlantic species. If you want tissue samples let me know.
That lump of slime and oil is over 2 kilos!
This one is now skeletonise (and is coming to the IoW this weekend. I have some smaller ones of other species and could fix one.
