R Guns of the Nagato Category: Wrecks Photographer: Niclas Andersson The Nagato is a famed Japanese battleship from which Admiral Isoroku Yamamoto is said to have issued the order to attack Pearl Harbour. Seized by the United States at the end of the Second World War, she was later towed to Bikini Atoll and used as a target ship during Operation Crossroads, the early nuclear weapons tests. Today Nagato rests upside down at roughly 52 metres, making it a demanding but highly rewarding dive. On descent, divers are greeted by four enormous propellers, while the standout features are the twin stern guns, best approached from the port side. Niclas Andersson / UPY2026
S A Meeting of Giants Category: British Waters Wide Angle Photographer: Evan Johnston What started out with two large sharks feeding at the surface off Scotland turned into three, then four, then five over the course of the day. At some point most of the sharks had gone, and after watching the last tail fade away, I turned around and was greeted with the image here. These sharks had stopped feeding and formed a tight shoal, before breaking off and swimming in slow rhythmic circles, eventually spiralling off into the deep. This behaviour is known as a torus and is thought to be a courtship behaviour. Evan Johnston / UPY2026
