Did You Know? The Hardest Animal on Earth
Our entire Universe is itself a mystery. There are thousands of facts that we still don’t know about our planet “Earth.” We might have several questions rounding in our mind about our world but we have not found answers to those questions. Science itself is filled with inscrutability.
Have you ever wondered about the hardest animal on our entire planet? Yes, hardest, Tardigrades are the hardest creature on our entire planet. At TechSpit, we will discuss about Tardigrades
What is Tardigrades
Tardigrades, often known as “water bears” or “moss piglets, ” are almost microscopic animal. They have eight legs and hands with four to eight claws in each. These tiny creatures are almost indestructible in nature.
They can grow up to 1.2 mm. They can range from 0.05 to 1.2 mm (0.002-0.05 inches). They usually don’t get larger than 1mm (0.04 inches) long.
Tardigrades can live almost anywhere in the entire solar system. They prefer to live in sediment at the bottom of fresh or salty water or mostly prefer moist places where they can get enough food to feed itself.
They are indestructible, they can withstand in any type of environment. Researchers have found that They can tolerate the environment as cold as -328° Fahrenheit (-200°Celcius) and as high as 302° Fahrenheit (150° Celcius). The longest time survived by a tardigrade without food and water is 32 years.
They can cope with 6 times higher pressure than the deepest parts of Ocean, and can also tolerate lack of oxygen and low pressure of the vacuum.
Tardigrades can also survive in outer space. But how they can cope up with these environments? The answer is- when the environment becomes “inhabitable” they undergo a condition known as “Cryptobiosis” they turn into a “Tun” state ( a lifeless ball). These creatures have also survived in Cryptobiosis state in Lab without food. They can even survive in volcanos too. They have exposed to a high level of gamma rays and other radiations but they still survive from that. This is why “Tardigrades” holds the title of the “hardest animal on earth.”
Life span of Tardigrades
Everything in nature is perishable including tardigrades. Generally, They live up to 2.5 years in active condition but in a dormant state (a state of rest, inactive) like Tun or cryptobiosis, they can live for more than 100 years. Waking after 100 years from tun state, they still have found alive- according to some Researchers.
Indeed their extraordinary ability to survive had made them alive till now from large asteroid crashing and gamma rays burst from Supernovas.
