How do sperm whales store oxygen?

Answer 1

Sperm whales store oxygen primarily in their lungs and blood. Their lungs have a large capacity, allowing them to hold significant amounts of air. Additionally, their blood contains a high concentration of myoglobin, a protein that binds oxygen, enabling them to utilize stored oxygen efficiently while diving. This adaptation allows them to dive for extended periods, often exceeding an hour, while searching for prey deep in the ocean.
