They are a diverse group of mammals with unique physical adaptations that allow them to thrive in the marine environment with extreme temperatures, depths, pressure, and darkness. Marine mammals are classified into four different taxonomic groups: cetaceans (whales, dolphins, and porpoises), pinnipeds (seals, sea.
Some marine mammals, such as whales, migrate over large distances and may spend time in a combination of arctic, tropical and temperate waters. To cope with these temperature changes, they are endothermic or ‘warm blooded’.
Jan 10, 2013 · Marine mammal adaptations: deep diving, swimming adaptations, thermoregulation, water conservation, and sensory adaptations.
Marine mammals have many adaptations that allow them to survive in various aquatic habitats. Figure 6.18 shows some examples of mammal adaptations. Fig. 6.18. ( A) Bats—the second largest mammalian group in terms of species diversity—can fly with the use of webbed wings.
Marine mammals are adept at thermoregulation using dense fur or blubber, circulatory adjustments (counter-current heat exchange); and reduced appendages, and large size to prevent heat loss. Marine mammals are able to dive for long periods.
The ocean environment presents extreme conditions for marine mammals that require extreme, almost superpower-like, adaptations in order to thrive. Adaptations are physical or behavioral traits that can be passed to offspring that help an animal survive and reproduce.
