The first place winner of the "Animals in their Environment" category went to Amos Nachoum for his photo of a penguin that is about to be eaten by a seal.
"A leopard seal got into a lagoon just before low tide," Nachoum wrote. "The seal was hiding, waiting to ambush young penguins as they got closer. When a penguin got close enough, the seal moved extremely fast and caught the penguin by its feet, dragging it to the open water. I was following parallel to the action. The seal released the penguin twice and the terrified penguin succeeded in escaping, but the seal continued chasing after it, and on the third attempt, drowned the penguin and devoured it."
