10 curiosities about animals
1. Snails sleep little: Sleep is usually short (like a 13-15 hour cycle followed by a 30-hour wake cycle) but can be longer in hibernation to protect them from the cold and not waste energy.
2. Elephants are the only animals that cannot jump: Elephants are the largest land animals in the world, weighing up to 6 tones and standing 3.5 meters tall. Too heavy, they cannot jump because they do not have the flexibility to lift all four legs at the same time. In addition, their knees will not withstand the weight of a fall and will break instantly.
3. Gorilla DNA is 95-99% similar to human DNA: 15% of people's genes are more similar to a version of the gorilla genome. The genetic variations between people and gorillas lie in the auditory and vocal systems that make us most different.
4. Hedgehogs see all yellow: Hedgehogs have a monochromatic vision, which means that instead of seeing all colors, they only see one color, yellow, which means they see on a yellow color scale. You can try to represent the latter by presenting a gray scale image, but with yellow. However, in good light, hedgehogs can distinguish certain colors.
5. Dolphins sleep with one eye open: Dolphins can stay awake and active for 15 days or more, sleeping with half their brain at a time, allowing them to sleep with one eye on the surface, so they can breathe and watch for predators.
6. Starfish have no brain: They are perhaps the most famous animals for not having a brain, but their function is carried out by a network of nerves, thanks to this organization starfish can coordinate their systems, including balance, movement, and direction.
7. Owls can turn 360 degrees: Owls have a very intelligent bone structure and a vascular system that runs from the neck to the skull. These features protect the blood vessels from damage and maintain blood flow, allowing them to turn their heads.
8. The body of a jellyfish is 96% water: About 96% of a jellyfish's body is composed of water, they move with the help of currents and propulsion mechanisms, drawing water into the digestive tract to expel it through contractions.
9. Giant tarantula spider capable of catching small birds: The Goliath tarantula, also known as the giant tarantula or aviary tarantula, is the largest spider in the world. It is so large that it can even eat birds.
10. Every cat's nose is different: Every cat's nose is unique, with unparalleled roughness, patterning, and dimpling. It distinguishes one feline from another like a human fingerprint. The same is true for dogs.
