Blue whales (Balaenoptera musculus) are the largest animals on Earth! They're so big that they are 36 times heavier than an elephant! Imagine that!
Even though they are enormous, blue whales are actually quite gentle. They eat the tiny krill and are typically solitary creatures. They spend the summer months in polar waters, then migrate to the equator in the winter to breed. Pregnancy lasts about 12 months.
Blue whales are also very loud. They make deep, rumbling sounds that can travel for hundreds of miles underwater. These sounds help them find other whales and communicate with each other.
Blue whales have the biggest hearts of any animal. Their hearts are about the size of a small car! Can you imagine a heart that big? Its heartbeat can be detected from 2 miles away.
They swim in all the oceans, except for the freezing Arctic Ocean. Usually, they like to swim alone or with a few friends. But when there's a lot of yummy food, they might have a big party with up to 60 other blue whales!
Blue whales are like giant vacuum cleaners of the ocean. In one day, they can eat as much as 16 tons of tiny shrimp-like creatures called krill. That's like eating 21 adult cows! Can you imagine how big their tummy must be?
