The mega porbeagle shark got here in at 500lbs and measured greater than 9 ft when it was bagged by native anglers Sid, Terry, and Peter from Counties Cork, Down and Antrim respectively.
The feminine was given the nickname Danu and scientists say she might be round 25-30 years outdated, the Irish Mirror stories.
Brave trio Sid, Terry and Peter had been joined by boffins from Trinity College Dublin who hooked up satellite tv for pc tags to Danu and picked up samples and measurements earlier than the spectacular beast was launched again into waters off the Donegal coast.
Within 48 hours she was tracked as distant because the Hebrides in Scotland.

One of the tags gives info on her migration historical past and ocean situations encountered and can detach in some months’ time.
The second ‘SPOT’ tag will present close to real-time knowledge on her location every time her fin breaks the water’s floor.
Nick Payne, shark biologist and Assistant Professor in Trinity’s School of Natural Sciences, mentioned: “It is exciting to see such huge porbeagles in Irish waters.
“The conservation standing of porbeagles has been actually regarding on this a part of the world, with the European inhabitants thought-about critically endangered.
“There’s evidence that the Donegal coast may act as a globally important reproductive area for this species, with lots of very large female sharks appearing here for a short period in Spring.”

Porbeagle sharks are literally shut kin of Great Whites and, regardless of their monstrous measurement, not often assault people.
The journey final week was the primary in a brand new analysis collaboration between Trinity, Inland Fisheries Ireland (IFI) and native shark anglers, along with main scientists from James Cook University (Australia), University of Miami and US non-profit Beneath the Waves.
Jenny Bortoluzzi, PhD candidate in Trinity’s School of Natural Sciences, took blood samples from the shark.
She mentioned: “This highlights once again both the importance of collaboration between scientists and anglers in a citizen science context and Ireland’s potential key role in conservation as a marine biodiversity hotspot.”
A second giant feminine porbeagle (round eight ft in size, nicknamed Sorcha) was additionally tagged and launched however she, not like Danu, determined to proceed cruising within the waters close to Donegal.
Overfishing has seen a extreme decline in porbeagle shares because the Thirties and industrial fishing by EU vessels has been prohibited since 2010.
