From immortal jellyfish and death-defying tardigrades to proposing penguins and voting bovines, here are three dozen randomly interesting facts about our planet's impressive array of animal life.
Earth is home to about 1 million known animal species, each one representing an ancient tome of biological trivia. Much of this random knowledge gets lost in the ether, leaving us to speculate about things like dinosaur divorce rates or amphibian dance moves. But we still catch an awful lot, providing us with plenty of interesting — if not always actionable — facts about our fellow fauna.
The list below is a tribute to such trivia. From extinct penguins to newly identified wasps, these tidbits reflect the depth of our own species' curiosity about nature — and our skill in shedding new light on it. As you peruse these facts, imagine all that went into discovering each one. We embrace their randomness here, but most hail from a robust body of knowledge about the animal in question.
So without further ado, here are 36 random animal facts that may interest you:
8. Humpback whale songs spread like "cultural ripples from one population to another."
9. Tardigrades are extremely durable microscopic animals that exist all over Earth. They can survive any of the following: 300 degrees Fahrenheit (149 Celsius), -458 degrees F (-272 C), the vacuum of space, pressure six times stronger than the ocean floor and more than a decade without food.
