What are the major differences between a whale shark and blue whale?

Size: Blue whales are the largest animals on Earth, reaching lengths of up to 108 feet (33 meters) and weighing up to 400,000 pounds (181,437 kilograms). Whale sharks are the largest fish in the world, but they are much smaller than blue whales, reaching lengths of up to 40 feet (12 meters) and weighing up to 47,000 pounds (21,319 kilograms).

Habitat: Blue whales are found in all the world's oceans, but they prefer the cold waters of the Arctic and Antarctic. Whale sharks are found in warm tropical and subtropical waters around the world.

Diet: Blue whales are filter feeders, meaning that they use their baleen plates to filter small organisms, such as krill and plankton, from the water. Whale sharks are also filter feeders, but they feed on a wider variety of organisms, including small fish, squid, and even plankton.

Behavior: Blue whales are social animals that live in pods of up to 100 individuals. Whale sharks are also social animals, but they tend to live in smaller groups of up to 10 individuals.

Reproduction: Blue whales give birth to a single calf every two or three years. Whale sharks give birth to live young, but the number of young they produce varies depending on the species.

Lifespan: Blue whales have a lifespan of up to 90 years. Whale sharks have a lifespan of up to 50 years.
