Dolphins filmed in 'especially rare' Essex river sighting
A pod of dolphins have been captured on video swimming and jumping near a river estuary in the UK.
Essex Wildlife Trust posted footage of the sighting in the River Crouch at the Blue House Farm nature reserve, near Burnham-on-Crouch.
A spokeswoman said: "It is rare to see them in the estuaries and especially rare to see them from Blue House’s sea wall."
