Stunning footage of a superpod of hundreds of dolphins has been captured on video by marine biologists off the Irish coast.
Wales-based organisation Sea Trust recorded the amazing footage as it was carrying out a survey on a Fishguard to Rosslare ferry when the common dolphins were spotted jumping from the water.
The charity conducts monthly surveys from the Stena Line ferry, and last week spotted the superpod about 10 miles off the Irish coast.
