Wildlife photographer Paul Goldstein has captured animals frozen in the air as they leap. Emperor Penguins, Snow Hill, Antarctica. Paul says: "Way down in Antarctica on the eastern peninsular I was stuck in the ice for a week along with 100 people. Off the stern of the ship we watched Emperor penguins on their migratory routes. You had to gamble where they were going to come up so virtually impossible to get the shot, but once one had jumped you could bet the others would follow, in this instance 'more is more' - this was the only time three jumped simultaneously.
