French photographer Eric Lefranc captured a picture of a bear in Alaska trying to catch fish on a stream. Lefranc recounted that the animal had spent the day deep in the water to grab the prey that plunged down from the falls, many successes and many failed attempts.

Dutch photojournalist Jan Vermeer took a picture of an antiquated seagull when he explored to the remote Varanger Fjord in Norway, where thousands of seabirds, including seagulls, gulls and Anca birds fly to reproduce.
