Mammals are vertebrates that have the ability to feed their offspring with milk. Their numbers are quite large, which explains their prevalence throughout the planet. Mammals have mastered well not only land, but also the waters of the seas and oceans, as well as air space. They are at the top of the food chain, eating both carnivores and plant-based foods.
