These adaptations help them survive in aquatic environments by allowing them to breathe, move efficiently, and stay warm in the water.

Amphibians and mammals are both vertebrates, but they have key differences in their characteristics and adaptations for survival. Amphibians typically have moist skin, lay eggs in water, and undergo metamorphosis, while mammals have hair or fur, give birth to live young, and produce milk to feed their offspring. These adaptations help amphibians thrive in aquatic environments, while mammals are better suited for life on land.
No, not all mammals have the same type of heart. While all mammals possess a four-chambered heart, which includes two atria and two ventricles, there are variations in size, structure, and function among different species. For instance, the hearts of larger mammals like elephants have different adaptations compared to smaller mammals like mice. Additionally, some mammals, such as whales and dolphins, have unique circulatory adaptations to support their aquatic lifestyle.
