Amazing facts about creatures big and small
Dolphins give each other unique whistle names and use them to call out to specific individuals in their group. When a dolphin hears its own name, it responds, much like a human would.
Vampire bats share blood meals with hungry roost-mates by regurgitating blood for them. They build strong social bonds and remember who helped them, returning the favor on future nights.
Male bowerbirds build elaborate, decorated structures called bowers to attract mates. They arrange colorful objects — berries, flowers, bottle caps — in specific patterns, and some even use an optical illusion to make their bower look larger.
Wood frogs survive winter by literally freezing solid — their heart stops, breathing halts, and ice crystals form in their blood. When spring arrives, they thaw out and hop away as if nothing happened.
Horseshoe crab blood is bright blue and contains a substance that detects bacterial contamination instantly. It is used to test every vaccine, injectable drug, and medical implant for safety before they reach humans.
When a pistol shrimp snaps its claw shut, the collapsing cavitation bubble briefly reaches temperatures hotter than the surface of the sun — around 8,000°C — and emits a flash of light. This phenomenon is called sonoluminescence.
The jellyfish Turritopsis dohrnii is considered biologically immortal. When it ages or is stressed, it can revert its cells back to their earliest form and restart its entire life cycle from the beginning.
Elephants are one of only a handful of animals that can recognize themselves in a mirror, a sign of self-awareness. Others with this ability include great apes, dolphins, and magpies.
The Australian lyrebird is one of the world's best vocal mimics. It can perfectly replicate the sounds of other birds, chainsaws, camera shutters, car alarms, and even human voices it has heard in the wild.
When a silverback gorilla beats its chest, the sound can travel more than a mile through the forest. Scientists have found that the loudness of a gorilla's chest beat accurately signals its body size to rivals.
