Janoš Vranek who was on the path near St Davids and saw what he felt was a whale breaching, He apologized for the quality of the film, estimating the size of the animal and distances is not easy but I think its something really big , my best guess would be a humpback! Posting the video's
Janoš sent not easy not sure if they work but hope it does! Its certainly very big whatever it was!
