The Polar Bear is a large species of bear that is found inhabiting the ice fields in the Arctic Ocean. It is the biggest species of bear in the world (with the exception of the KodiakBrown Bears found in Alaska which can reach similar sizes) with males often weighing-in at around 600kg. Thought to be closely related to the Brown Bear, the Polar Bears' name actually means "Sea Bear" as they are known to not just spend a great deal of time close to the coast, but are also strong and capable swimmers that have been spotted up to 100 miles from the closest ice or land.
