Whale

Did you know that the blue whale is the largest animal ever known to have existed on Earth? These magnificent marine mammals can grow up to 100 feet (30 meters) in length and weigh as much as 200 tons (181 metric tonnes)! To put that into perspective, the heart of a blue whale alone can be the size of a small car and weigh as much as 1,300 pounds (600 kilograms).
Despite their enormous size, blue whales primarily feed on tiny shrimp-like animals called krill, consuming up to 4 tons (3.6 metric tonnes) of krill per day during the feeding season. Their sheer size and unique adaptations make them truly remarkable creatures and a symbol of the awe-inspiring diversity of life in the oceans.
