    • Example: Hippo, one of the largest land mammals, known for its aquatic lifestyle and herbivorous diet.

    Cetacea (Whales)

    • Highly intelligent marine mammals with large, complex brains and minimal body hair.
    • Use blowholes for respiration located on the tops of their heads.
    • Example: Dolphin, known for social behavior and advanced learning capabilities.
