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.
