What is the humerus function in a whale?

In whales, the humerus is a crucial bone that plays a significant role in their flipper structure. It helps support the flipper's form and aids in locomotion, allowing for powerful and efficient movement through water. The humerus connects to the shoulder girdle, facilitating the range of motion needed for swimming and maneuvering. Overall, it is essential for the whale's adaptation to an aquatic lifestyle.
