Why Are Marine Mammals So Big

The video explores why marine mammals are large, challenging the idea that buoyancy alone allows for their size. It discusses the evolutionary background of marine mammals and analyzes body size patterns, revealing that thermal regulation plays a significant role. While most marine mammals converge around 500 kg, outliers like baleen whales and sea otters show different size adaptations. The findings prompt a reevaluation of marine life understanding, highlighting the complexity of scientific inquiry.

Why is 500 kilograms considered an optimal size for marine mammals?

What unique adaptations do baleen whales have that allow them to grow larger?
