Close to Wrangel island, we came upon three Polar Bears near a Walrus Carcass. This was the third Walrus kill we had seen. Surprisingly we had seen few seals so the bears had had to resort to taking young Walrus.
The Polar Bear (Ursus maritimus) is the iconic species of the Arctic. They are normally found near the floe edge where they hunt seals most notably Ringed Seals. On this trip we found several bears on Walrus kills and saw very few seals. Polar Bears will also take Beluga Whales and Narwhal. Males can reach up to 800kg and stand up to 1.5m at the shoulder. The fur is made up of a thick under fur up to 5cm long with guard hairs that can reach 15cm in length. These hairs are hollow thereby increasing their insulating properties. Beneath the skin is a thick layer of blubber up to 15cm thick. Polar Bears stroll across the ice at a leisurely 4km/hr – any faster and they get too hot. When needed they can run in short bursts at 40km/hr. Polar bears are adept swimmers reaching up to 3km/hr and can swim very long distances.
