'Elusive' animal spotted swimming in river near Glasgow
John Hutton captured this image of one of two otters he spotted in the Allander Water earlier this week.
The otter is described by the RSPB as one of the most difficult to spot in and around Glasgow, and is often confused for much the smaller American mink, but are more elusive.
Despite being a rare sighting, they have been spotted more frequently in the River Clyde, North Calder, River Kelvin, White Cart Water and the Forth and Clyde Canal.
The slightly more common sightings are thought to be thanks to the cleaner water in rivers which means they have more prey to catch.
