Have you ever wondered why penguins 🐧 live only in the Southern Hemisphere and never in the North? br Their main home is Antarctica ❄️ but you can also find them on the rocky coasts of South America 🌎 br the shores of South Africa, Australia and New Zealand. Still, they never cross the equator 🌍 a natural ecological boundary br that keeps them in the south. Millions of years of evolution shaped penguins into expert swimmers 🏊‍♂️ Fossils found in New Zealand br even reveal ancient giant penguins so massive they were taller than humans and weighed over 100 kilograms! 🦕🐧 Their survival depends on cold waters, br the hot equatorial seas are deadly, with high temperatures and almost no familiar food 🌡️ Another reason penguins thrive in the south is safety. In the Arctic, br polar bears 🐻‍❄️ dominate the land, but no such predators exist in Antarctica. This allows penguins to live and breed in relative peace on the southern side of the Earth.
