Marine Mammals

Definition of Marine Mammals as it relates to Animals, Zoo Animals, Fish

Marine mammals are warm-blooded aquatic vertebrates that rely on the ocean and its resources for their survival. They belong to several different taxonomic groups, including whales, dolphins, porpoises, seals, sea lions, walruses, manatees, and dugongs. Marine mammals are characterized by their adaptations to life in the water, such as streamlined bodies, flippers or fins, and the ability to hold their breath for extended periods of time. They have a high metabolic rate and must consume a large amount of food to maintain their body temperature. Many marine mammals are migratory and travel long distances between their feeding and breeding grounds. They play important roles in the marine ecosystem as predators, prey, and sources of nutrients. Despite their adaptations to life in the water, marine mammals still require access to air to breathe and must surface regularly to do so. Some species are threatened or endangered due to human activities such as hunting, habitat loss, and pollution.
