The Beluga

 This marine mammal is commonly referred to simply as the beluga or sea canary due to its high-pitched twitter. A beluga can weigh up to 1,500 kg, and up to 40 per cent of its body weight is blubber! It is up to 5 meters (16 ft) in length and an unmistakable all-white color with a blow hole for air on it's head. From a conservation perspective, the beluga is considered "near threatened" by the International Union of Conservation Nature.
