In the summer time they can be close to the shore as well, but only in short period. They travel in scoals and inhabit areas were there are huge scoals of small coalies. The size of the porbagleas are from 70 to 150 kg.

Blástein has done some research on porbeagles together with French marine biologist from Ifremer. and also Canadian marine biologists from Bedford institute of Oceanography. We have found out that some mature female travel from north of Norway to San sebastian in the bottom of the Biscaya bay. One porbeagle was tagged in November in Faroe, and was traced in closo to San Sebastian in late july. A few months later, in september it was found on the shelf in west of ireland.
