Top 9 Reasons Tardigrades Are Super Animals

In April 2019, thousands of dehydrated tardigrades, human deoxyribonucleic acid samples, and alternative payloads were sent to the Moon. however the pod crash-landed, and therefore the project developers square measure convinced that these small organisms could also be the sole ones UN agency survived the mission.

Tardigrades, conjointly typically known as “water bears,” square measure microscopic creatures which will survive in nearly any setting. it’s noted that scientists managed to bring tardigrades back to life once thirty years of deep chilling. Being extremophiles, tardigrades close up their metabolism and survive in harsh environments for terribly long periods. Tardigrades will face up to pressure equivalent to AN asteroid falling on Earth, thus AN aircraft landing, just like the one that happened on the Moon, is nothing for them. These creatures square measure in theory capable of living on the Moon for many years. Fascinating, isn’t it?


Here square measures a lot of extreme facts concerning the hardiest creatures on our planet.

1- Tardigrades were initially discovered in 1773 by a German pastor named Johann August Goetze. In 1776, the Italian life scientist Lazzaro Spallanzani gave it the Latin name class, which implies “walking slowly.”

2- Since 1778, quite 1150 species of tardigrades are discovered.

3- Arthropod babies square measure born with a full set of adult cells. they are doing not grow by biological process. Their cells merely increase in size.

4- Tardigrades are living on Earth for concerning 530 million years.

5- Tardigrades square measure small, microscopic animals with segmental bodies. They reach zero.5 to one millimeter long. they need four pairs of legs, every with 4-8 claws resembling bear claws. For this feature, they’re typically known as “water bears” or “moss piglets,” as they’re typically found in the nonvascular plant.

6- These water-dwelling creatures live everywhere on the planet within the most extreme places, like the Antarctic ice, within the ocean depths of up to 4000 meters, high within the Himalayas at AN altitude of 6000 meters, on tree trunks, on moss, in soil, on the beach and anyplace else. of these water bears want could be a little bit of humidness.

7- Most often, tardigrades prey on a bacterium, plants, and even alternative tardigrades. They penetrate individual cells of their prey, consuming its contents to get nutrients. within their weird-looking mouth, they need sharp dagger-like teeth that they use to pierce alternative living organisms and alga.

8- Once tardigrades have enough food and water to support basic functions, they’re going through a natural life cycle that seldom lasts quite two. or 5 years. However, these water bears will live for much longer if they enter a state of physiological state once environmental conditions become unendurable. Contrary to in-style belief, tardigrades don’t live forever. Stress from chilling, radiation, and therefore the extreme temperature still affect their physiology.

9- Scientists froze them down to -200 °C, and they were ready to survive for many days. Then they cooled the small dudes all the way down to -272 °C (which is one degree higher than absolute zero), and they still lived for many minutes.
