Alan McKenna, from volunteer research group Loch Ness Exploration, was on a boat using a hydrophone system to capture the underwater sounds of the Highlands loch.

He said when they were testing the system on Friday, they heard four distinctive “gloops”.

“We all got a bit excited, ran to go make sure the recorder was on and it wasn’t plugged in,” he sheepishly admitted.
