British Waters Wide Angle category runner-up. Grass snake swimming along a garden pond by Jack Perks (UK)in Nottinghamshire, UK. “I’m always on the lookout for unusual freshwater subjects and grass snakes are a species I’ve been after for years. I was told about a pond where the odd grass snake hangs around the lilly pads for frogs. I put my drysuit on and got into the water and could see one slithering along the surface. Slowly making my way towards it with my head only just poking above I got the spilt shot”. (Photo by Jack Perks/Underwater Photographer of the Year 2019)
