The Sea of Okhotsk lies between the Kamchatka Peninsula and the Japanese island of Hokkaido: the last and greatest unspoiled ocean on Earth. It can be harsh and unforgiving; temperatures drop to -40 degrees, typhoons and tsunamis lash the shores. But it's also a wildlife paradise where animals grow bigger, stronger and more numerous than anywhere else. Its iconic animals are giant brown bears, the world's biggest sea eagles and the acrobatic spotted seals. Grizzlies here dip into the thermal baths and geysers left by the world's most active volcanoes. The few human inhabitants are held by the glory of the natural spectacles, including the world's largest seabird colonies, orca pods and humpback whales.
