Cetacean (whales, dolphins)

Cetaceans, including whales and dolphins, are a group of aquatic mammals highly adapted to life in the water. They possess streamlined bodies for efficient swimming, blowholes on top of their heads for breathing, and advanced echolocation abilities to navigate and hunt in murky depths. Cetaceans are social animals, often living in groups, and exhibit complex behaviors and communication. They breathe air through lungs, must surface regularly, and are found in oceans worldwide. These mammals play vital roles in marine ecosystems and display remarkable intelligence and adaptability.
