Furthermore, their sensory world is dominated by sound; many species use sophisticated echolocation to navigate and hunt in the dark ocean waters, while others rely on complex vocalizations for communication over vast distances. Key Anatomical and Physiological Adaptations The cetacean definition is perhaps most vividly illustrated through its extraordinary physical adaptations.

Modern taxonomy divides this order into two primary suborders: Mysticeti, the baleen whales, and Odontoceti, the toothed whales. Understanding this structure is fundamental to grasping the full scope of the cetacean family tree.
A thick layer of blubber replaces fur, offering insulation, energy storage, and buoyancy control. Forelimbs have evolved into rigid pectoral fins for steering, while hind limbs have completely disappeared within the body.
