Twelve underwater photographers have compiled their best images into a calendar to raise funds for the marine conservation charity, Bite-Back. This picture of a manatee was captured by David Fleetham in the US.
The aim of the calendar is to highlight key issues affecting the marine environment. Amos Nachoum, who is pictured here with a great white shark, hopes to dispel the Hollywood studio myth that surrounds the animals.
Every year 70 million sharks are killed for meat and fins. The charity says that, at that rate, 12 species could be extinct by 2017. Basking sharks, like this one photographed by Doug Perrine, are vulnerable to extinction.
Alex Mustard took this picture of a grey seal off Lundy Island in the UK. He says that only a tiny percentage of the British seas are “truly protected” from fishing and pollution.
These manta rays were photographed by Michael Aw off an islet called Hanifaru in the Maldives. When the conditions are just right, high concentrations of plankton attract hundreds of rays and some whale sharks.
This is the only swordfish that photographer Jeff Rotman has ever encountered. “We both seemed rather surprised to see each other,” he said.
