| Definition: |
Marine mammals represent three different orders of mammals: the Carnivora, Cetacea, and Sirenia. Species in these orders occupy typically marine habitats and evolved similar anatomical features, including large body size, streamlined shape (compared to terrestrial relatives), insulation in the form of blubber and dense fur, and in most cases, a modified appendicular skeleton resulting in reduction in the size of appendages. Marine mammals also possess some similar physiological adaptations (e.g., for diving, thermoregulation, osmoregulation, communication, and orientation) to permit them to exploit the aquatic environment. |
