Animals

Tardigrades (TAHR-di-greyds), often called water bears, are near-microscopic animals with long, plump bodies. They have eight legs, with four to eight claws on each. While strangely cute, these tiny animals are almost indestructible.

Water bears can live in just about any type of water body. They prefer to live in sediment at the bottom of a lake, on moist pieces of moss or other wet environments. They can also survive a wide range of temperatures and situations. 

Researchers have found that tardigrades can withstand environments as cold as -200˚C (-328°F) or highs of more than 149˚C (300°F). They can also survive radiation, boiling liquids, massive amounts of pressure (up to six times the pressure of the deepest part of the ocean), and even the vacuum of space, without any protection. A 2008 study found that some species of tardigrade could survive 10 days at low Earth orbit while being exposed to space vacuum and radiation. 

The battle between cat and dog lovers is well-known. Some people love dogs. They say that dogs are friendly, loyal and active. Other people prefer cats. According to cat lovers, cats are independent, lower maintenance and cute. Some people choose very different pets, such as fish, birds, or rodents (e.g. rats, mice, guinea pigs).

An abandoned dog named Hector was left tied to the gates of an RSPCA (Royal Society for the Prevention of Cruelty to Animals) branch in West Yorkshire, England. When trying to give commands to the dog, staff found that Hector was not reacting. Luckily for Hector, the staff decided to try other languages, and it turned out he knew several commands in German.

Care manager Lucynda Hodgson said they started to introduce him to English words. To help Hector understand them, the staff used hand signals together with verbal commands, and he picked them up really quickly. Lucynda added, "He's a very intelligent dog and is very loving." After about three months of polishing his English skills, Hector reacted perfectly to English commands.

Onomatopeia is a fancy way to describe words that sound like what they mean. For instance, in English, bees "buzz" and cats "meow". Words for animal sounds are almost always built on how the animals actually sound to listeners. But that can be different in different languages. Since each language has its own set of sounds to work with, they hear animals based on those sounds.

For example, a rooster's crow is translated as:

• "Cockadoodle doo!" in English;
• "Kikiriki!" in Spanish; and
• "Kok-e-kok-ko!" in Japanese.

This video shows people from all over the world saying animal sounds in their language. How would you write the sounds the animals make in your language?
