The Bahamas Hosts the World's Largest Colony of West Indian Flamingos

Cats, like most birds, fish, reptiles, and amphibians, possess a nictitating membrane — a translucent third eyelid that moves horizontally across the eye from the inner corner. Normally hidden in healthy, alert cats, it becomes visible when a cat is drowsy, ill, or under stress. Humans lost this structure through evolution.

In Utah's Fishlake National Forest, a clonal grove of quaking aspen trees named 'Pando' (Latin: 'I spread') consists of about 47,000 individual stems that are genetically identical, sharing a single root system. Weighing approximately 6,000 metric tons and covering 43 hectares, it is estimated to be 80,000 years old.

Chameleons are not actually great at camouflage — their resting color already blends with their surroundings. Rapid color changes serve primarily as social signals: males flash bright colors during courtship or to threaten rivals, dark tones indicate fear or submission, and bright hues signal excitement. A 2014 study by Stuart-Fox confirmed communication as the primary function.

In the Malheur National Forest, Oregon, a single Armillaria ostoyae (honey fungus) spreads across 965 hectares (2,385 acres) — roughly 1,350 football fields. Estimated to be about 8,000 years old, it grows mostly underground as mycelium. Discovered in 1998, it broke the previous record held by a similar fungus in Michigan.
