Mammals, though representing a small fraction of Earth's biodiversity, play indispensable ecological roles worldwide. Their contributions to ecosystem health, including pollination, seed dispersal, and predator-prey dynamics, are crucial. A recent visualization on the Voronoi app has captured attention by illustrating the average lifespans of mammals, drawing on data from Discover Wildlife and the United Nations . Human Lifespans on the Rise Mammals, defined by their warm-blooded nature and possession of hair or fur, nurture their young with milk from mammary glands. While some, like weasels, typically live only 1-2 years, others, such as elephants, can thrive for decades, and bowhead whales can live for over 200 years .
