Marine Mammals are warm-blooded, air-breathing mammals that live in marine environments. They are characterized by their adaptations to life in the ocean, including having a streamlined body shape for efficient swimming, and specialized limbs or flippers for maneuvering through water. As part of Marine Animals Adaptation, this group includes animals such as whales, dolphins, seals, sea otters, and manatees, among others. Each species has developed unique features to survive in their specific marine habitats, from the deep ocean to coastal areas. For example, whales have developed specialized blowholes for breathing at the surface, while seals have evolved thick layers of blubber to insulate them from cold water temperatures. Marine mammals play important roles in Marine Ecosystems by serving as both predators and prey, and contributing to nutrient cycling. They are also an integral part of Marine Life, and their presence or absence can indicate the health of marine ecosystems. Understanding how these animals have adapted to life in the ocean can provide valuable insights into the evolution of marine biodiversity and inform conservation efforts.
