#MarineWildlife - BBC News has some incredible footage of a 'superpod' comprising hundreds of dolphins in the Irish Sea captured this week.

The video was shot by surprised researchers with the Wales-based Sea Trust on one of the groups routine survey expeditions between Fishguard and Rosslare on board the Stena Europe ferry.

Cliff Benson of the marine wildlife charity described the sea as "boiling" with dolphins just 10 miles off the Irish coast yesterday morning.

"They were just coming and coming. It was the last thing on earth I was expecting in the winter," he said. "We had at least 250 and that's a conservative estimate. I'm guessing there was as many as 500."

The incredible sight comes just a month after the researchers recorded what they called a "dolphin-fest" along the same route west of Tusker Rock, numbering more than a 100 dolphins and 26 porpoises.
