8 Coisas Que Você Não Sabia Sobre os Animais - Summary

Summary

The text discusses incredible animal facts, including:

1. Animal hypnosis: Chickens and even alligators can be hypnotized using simple techniques, such as drawing a line on the ground for chickens or carefully holding the alligator's mouth and turning it onto its back.

2. Tree frogs can survive freezing temperatures and thaw out in the spring, with some species able to withstand temperatures as low as -20°C.

3. Elephants can hear through their paws, using special nerve endings to detect vibrations in the ground.

4. Crows may hold "funerals" for dead crows, gathering around the body and making loud noises, possibly as a way of warning other crows of potential danger.

5. Ants can kidnap other ants, with red ants raiding the nests of black ants and stealing their young, which are then raised and brainwashed to think they belong to the red ant colony.

6. Woodpeckers have a unique way of storing acorns for winter, drilling holes in tree trunks that fit the acorns perfectly, making it difficult for other animals to steal them.

7. Owls have evolved to be silent flyers, with special feathers on their wings that minimize noise, allowing them to hunt at night without scaring their prey.

8. Rattlesnakes use their iconic rattle to warn potential threats, shaking their tails 40-60 times per second to produce a menacing sound, which is created by the friction of keratinous rings on their tail.

9. Frogs prevent dehydration by surrounding their cells with glucose.
10. Elephants can hear through their paws using special nerve endings that capture vibrations.
11. Elephants can communicate with each other through these vibrations, which are emitted by their relatives.
