It encompasses the vast Amazon basin, the intricate landscapes of Central America, and the unique ecosystems of the Caribbean. These boundaries often align with geological barriers like oceans, mountain ranges, and vast deserts, which prevent species from migrating and mixing.

Instead, it clusters in distinct regions where species share common evolutionary histories and face similar environmental pressures. Over millions of years, isolated populations diverge, leading to unique assemblages of life that define each realm.
This realm is defined by an unparalleled richness of life, including countless plant species, jaguars, harpy eagles, and an immense variety of insects and amphibians. The ancient connection of South America to Antarctica and subsequently to North America via the Isthmus of Panama dramatically reshaped its biological composition through the Great American Interchange.

Understanding these realms is essential for grasping how geography, climate, and deep time have shaped the planet's biodiversity. The concept of a biogeographic realm emerged from the work of 19th and early 20th-century naturalists who observed sharp transitions in flora and fauna across continents and oceans.
