National Geographic on Instagram: "Known for their iconic tusks, which may help them sense changes in their icy environment, narwhals navigate the Arctic waters as mixed pods of males, females, and juveniles. This pod was encountered by Martin Gregus Jr. (@mywildlive), and while barely visible from the water's surface, a bird's-eye view reveals the full extent of their movements and behaviors."

National Geographic Animals on Instagram: "It’s all love until someone throws a paw. Polar bears spar to test their limits and prepare for the real battles ahead. ❄️"
