The bowhead whale’s name comes from the bow-shape of its large upper jaw. Its jaw holds the longest baleen plates of any whale, reaching up to four meters long! Bowhead whales use these plates to filter water for food, like zooplankton, krill and small fish. Their large heads makes up one third of their body length and are encased by a thick layer of blubber. This allows them to explore waters farther north than other whales, which helps them to avoid predators like killer whales. Bowhead whales also use their large heads to smash through ice  more than 20 centimetres thick. This ice smashing often leaves bowhead whales with distinct scars that scientists use to identify different individuals.
