Japanese scientists, while on their journey to Antarctica, found a pile of moss which harbored a strange creature. Surprisingly, this incident happened back in the year 1983.
Scientists found that the creature living in that pile of moss was tardigrades. They are animals of about one-millimeter long. Interestingly, the animals resembled very close to a teddy bear crossed with a caterpillar.
Some people also name them as water beans. On the other hand, the scientists found the moss wrapped up in a paper. Also, they found the paper lying in a plastic bag. Surprisingly, scientists concluded that someone locked them away inside a freezer with -4 degree F temperature. Since then, they froze for over thirty years.
Tardigrades Have Remarkable Survival Ability
By the looks of it, the whole scenario sounds horrible. But, in the year 2014, the scientists observed tardigrades in the year 2014. Without a doubt, the animal moseyed around while they placed it in a plate. Further, the animal then reproduced.
Nevertheless, scientists are yet learning about the animal, tardigrades. Besides, they are also learning their survival ability. And it is remarkable. In addition to it, the scientists discovered the adaptation ability of the animal. As a result, they found out that animals have different species. Interestingly, tardigrades are capable of adapting to different kinds of environmental threats.
Moreover, during hot conditions, the tardigrades release proteins which are heat-shock. Such proteins prevent other ones from warping. Furthermore, some tardigrades also can form cysts around its bodies. Hence, cysts allow the tardigrades to survive even in harsh climatic conditions. And, the bubbly cysts act like a puffer jacket during such conditions. Conversely, when it comes to dry conditions, cysts allow the tardigrades to shrink down. Precisely, they can shrink into a protective tun, which is like a pill shape.
