Blue Whales are very mysterious. They are marble blue. They have a blowhole. They are mammals. They are streamlined and tapered so they can swim faster. They are usually very smooth. Their dorsal fin is curved. Their flippers are tapered. The fluke [the part you would see when a whale dives is broad and triangular.

Blue Whales live in awesome places. They live in all oceans. They move to different places as the seasons change. When they are alone they stay near the equator. Their feeding trail is hard to follow.

Blue Whales have a cool way of taking care of their babies. Their babies are called calfs. Calfs are born in warm water. They are born every 2-3 years. Twins are rare but sometimes they occur. Most animals don’t come after them because of their huge size. They feed their calf’s milk.

Blue Whale facts are awesome! They weigh over 160 tons. They are the biggest animals in the world. Their water spouts go 30 feet in the air. They are bigger than 23 adult elephants.    They are 98 feet long. The longest one ever recorded was 210 feet long. Their life span is 80-90 years. They have blood vessels humans can swim through.

Blue Whales eat awesomely. They eat mostly krill but in Baja, they eat red crabs. They eat 4 tons of food a day. They have baleen. Baleen helps water go out of a Blue Whales mouth and not the food. They eat many types of food.
