Amazing facts about creatures big and small
Axolotls can regenerate not just limbs but also parts of their heart, brain, and spinal cord. Scientists are studying their regenerative abilities to understand how similar healing might one day be triggered in humans.
Ostriches are the fastest running birds on Earth, reaching speeds of 45 mph. A single stride can cover 10 to 16 feet, and they can maintain high speeds for long distances.
The blue-ringed octopus is about the size of a golf ball but carries enough venom to kill 26 adult humans within minutes. There is currently no antivenom, and victims must be kept on life support until the toxin wears off.
Cuttlefish hypnotize crabs and shrimp before attacking by creating mesmerizing pulsing waves of color across their skin. The prey freezes, and the cuttlefish strikes.
A great white shark can detect a single drop of blood in 25 gallons of water and can smell blood from over a mile away. Up to 70% of a shark's brain is devoted to processing smells.
The kiwi bird lays the largest egg relative to its body size of any bird on Earth. Its egg can be up to 20% of the mother's body weight — the equivalent of a human giving birth to a six-year-old child.
The peregrine falcon is the fastest animal on Earth, reaching dive speeds of over 240 mph. Special bony tubes in its nostrils slow the air rushing in so it can breathe while diving at full speed.
Octopuses are colorblind yet can perfectly match the color of their surroundings in an instant. Scientists think their skin may contain light-sensitive cells that allow it to 'see' and match colors independently of the brain.
Crocodiles cannot stick out their tongues — their tongues are fused to the roofs of their mouths. Despite this, they are warm and caring parents, gently carrying hatchlings to water in their jaws.
Inside a chrysalis, a caterpillar does not simply grow wings — it completely dissolves into a soupy liquid and rebuilds itself from scratch into a butterfly. Remarkably, some memories from the caterpillar stage survive this process.
