Pod of orcas hunt seal off Fair Isle
Footage shows a pod of orcas surrounding a grey seal along the coast of Fair Isle.
People heard the orcas squeaking to each other and watched them hunt the seal for about 30 minutes.
David Parnaby said: "Although we get killer whales here most years that was my most impressive sighting yet".
The seal escaped unharmed.
