Barmouth (UK), 5 december 2014 – A shark provisionally identified as a mako (Isurus oxyrinchus) was found dead stranded today at Barmouth in Gwynedd. Mako sharks are thought to be occasional seasonal visitors to UK waters.
And last year, a report of a mako shark caught by fishermen in Welsh waters appeared in the media, http://www.bbc.co.uk/news/uk-wales-south-west-wales-23375902
Update 7 december 2014
Marine Environmental Monitoring carried out an examination of the mako shark (Isurus oxyrinchus) yesterday afternoon, whilst in the vicinity of the stranding. Unfortunately the carcass had been opened up overnight and many of the teeth had been removed, presumably by trophy hunters. The dismembered remains of a recently ingested harbour porpoise were found within the stomach of the 2.67m female shark. Mako sharks feed on a range of prey species, primarily cephalopods, and bony fish as well as marine mammals like harbour porpoises.
