Moving footage has emerged of a dolphin that strayed into a Welsh river and into English waters in Cheshire.
The footage is understood to have been captured on Monday at Connahs Quay Docks in Flintshire.
From there the dolphin was seen further up the river in Saltney, near Chester and was most recently seen near Chester Racecourse.
Marine experts think the common dolphin, which is usually more at home in the deep seawater of the Bay of Biscay, must have been chasing fish up the River Dee in North Wales.
The dolphin is being monitored by a marine charity in case it gets stranded on a sandbank.
