Picture of the day

Underwater photographer Henry Jager, 43, photographed this glowing jellyfish on a visit to Marsa Shoona in Egypt. 'I wanted my photograph to play with the tension being close to potential dangerous but extremely beautiful animal,' said Henry. 'On the one hand you can enjoy the beauty of the jellyfish, but on the other hand it's very frightening, and I often get people asking me how I dare to go that close.'
