EXTREME SPECIALIZATION. “Cetaceans are arguably the most specialized of all mammals, having evolved from a terrestrial ancestor to occupy an obligate aquatic niche. Modern cetaceans show numerous phenotypic adaptations for life in the water; aside from the radical reorganization of their forelimbs into fins and loss of hindlimbs, they are able to dive and tolerate low oxygen, and possess modified circulatory and respiratory systems, large brains, hairlessness and transformations in sensory perception.”
