Mysterious ‘green mass’ spotted in waters of Loch Ness fuelling fresh Nessie rumours

A mysterious green mass has been spotted in the waters of Loch Ness, fuelling fresh rumours about the monster which is said to lurk in its depths.

The object was caught on camera next to Urquhart Castle by a tourist on a Jacobite Cruises boat tour on June 23.

Sharon Herbert had been taking a picture of the castle – but spotted the strange sight lurking just beneath the surface. It is the seventh possible Nessie sighting to be made this year.

The picture, recently uploaded to the official Loch Ness monster sightings register, also left the experienced skipper of the tour boat flummoxed.

The register said: ‘Sharon Herbert, visiting from Kent, took a picture of an unknown object close to the Jacobite cruise boat at 10.27am as it came to shore at Urquhart Castle.’

‘Jacobite Cruises have confirmed that their skipper says there is no explanation that they can offer as to what the green mass is.’

The incident is the latest in a busy year for Nessie spotters with six in-person sightings and another via webcam since the start of the year.

By comparison, the register only recorded six in-person and four webcam sightings for the whole of 2025.

The official Loch Ness Monster sightings register has recorded a total of 1,172 sightings to date.

Scientists have long cast doubt on the existence of the aquatic being, with the famous 1933 photograph of a long-necked creature swimming in the lake dismissed as a hoax.

Nevertheless, thousands of people still head to Loch Ness every year armed with cameras in the hopes of catching a glimpse of its most famous resident.

In April, the mythical creature was ‘spotted’ twice within a few days after months without a glimpse of it.

And in December 2024, it emerged the sightings could be down to ‘standing waves’,according to Alan McKenna, the founder of Loch Ness Exploration (LNE).
