What are Structural adaptations for blue whale?

Structural adaptations of blue whales include their streamlined body shape, which reduces water resistance during swimming. They possess large, paddle-like flippers and a powerful, flat tail fluke that aid in propulsion. Additionally, their baleen plates allow them to efficiently filter small shrimp-like creatures, such as krill, from the water, enabling them to consume large amounts of food. Their size, being the largest animal on Earth, also helps in thermoregulation and deterring predators.
