Boaters film close encounter with a basking shark

Huge shark filmed off coast of Northern Ireland

Close Encounter with a Basking Shark in Portrush, UK

This video clip shows a close encounter with a large and beautiful basking shark off the County Antrim coast near Portrush in Northern Ireland.

The clip, taken earlier this month, was filmed from a small boat - but the shark thankfully isn't a danger to humans.

The harmless, plankton-eating creature, which has no teeth, is the world's second largest living fish after the whale shark and can grow up to 33ft long.
