The enormous gape of a playful Leopard seal - Bartosz Strozynski

A dramatic picture of a leopard seal snapping its jaws directly at the lens of Bartosz Strozynski, landing him the gold award for animal behaviour.

"I was playing with the seal," said 35 year-old Bartosz from Poznan in Poland. "They are curious and they do try to test you in the water.

This one saw his reflection in my lens and must have thought I was another leopard seal. So she displayed her teeth as a warning."
