Mammals

Definition of Mammals as it relates to Animals, Pet Trade Animals

Mammals are a diverse group of warm-blooded, vertebrate animals characterized by the presence of mammary glands, which produce milk to nourish their young. They belong to the class Mammalia and are found on every continent except Antarctica. Mammals can be further classified into three main groups: monotremes (egg-laying mammals such as the platypus), marsupials (pouched mammals such as kangaroos and koalas), and placentals (mammals with a placenta, such as humans, dogs, cats, and livestock). Mammals exhibit a wide range of adaptations to their environments. Some are excellent swimmers, such as seals and whales, while others are skilled runners, such as antelopes and cheetahs. Mammals also have highly developed sensory systems, including sophisticated hearing and vision, which allow them to detect predators and navigate their surroundings. Mammals play a critical role in many ecosystems, serving as both predators and prey. They are important indicators of environmental health, as changes in mammal populations can signal broader ecological disturbances. Additionally, mammals have significant cultural and economic value for humans, serving as companions, food sources, and objects of research and conservation efforts.
