In this experiment, Sandra took a defrosted moss sample and surprisingly, she found out a group of Tardigrades coming out alive after a 30 years long state of dried up tardigrades. In such harsh environments, no other animal is able to survive more than 5 seconds.Īn experiment was done by a Tardigrade researcher Sandra McInnes in 1983 for observing the Tardigrades lifespan under extreme conditions. What makes Tardigrades unique is their ability to withstand the extreme environment and living a very long life under these environments. Instead, they breathe from their skin pores throughout their body. They do not possess respiratory organs to breathe. Tardigrades do not breathe like most of the other animals. Even baby tardigrade take birth with the same number of cells as its parent. The front 2 legs are used to grab the floor to move forward whereas other 6 legs are used to grab food.Īnother interesting fact about Tardigrades is that each tardigrade from same species consists of exactly the same number of cells. They have 4 claws made up of chitin at the end of each leg that helps in grabbing things to move forward. They generally range in size from 0.1mm to 1.5mm. Tardigrades are microscopic animals with a head and 8 limbs whose size varies from species to species. These newly discovered creatures became popular with the name of water bears due to their walking movement resembles with that of bears and they generally live in fresh water. In total, there are more than 950 species of tardigrades that are categorized into 3 classes: Tardigrades were first discovered by a German pastor in 1773. Tardigrades: One Of The Oldest Living Species Of Animals Scientists, in curiosity, to know more about them, threw them into the outer space and to their surprise, Tardigrades survived all those harmful gamma radiations from the Sun. They can handle the as high pressure as 500 megapascals which is around 5 times the pressure at sea floors. Tardigrades have the ability to live under extreme conditions which no other animal can. The most interesting thing about tardigrades is their strong desire to live. They are the only species of animals that can live in outer space. Tardigrades are micro-animals that are found everywhere on the Earth including ocean beds, lakes, forests and even mountains covered up with snow. Interestingly, in the extreme condition, it enters into a state of cryptobiosis in which it can survive even for 50 years without food and water. So, how long do Tardigrades live? According to the study done by the University of Michigan, an average healthy tardigrade lives for nearly 3 years if have enough food and water available. In this article, I’ll answer this topic in detail. With so much hype about tardigrades, many people are curious to know about tardigrades lifespan. Tardigrades, also known as water bears are considered cutest micro-animals and are resilient enough to survive through extreme conditions (even in space). Have you seen a cute micro-animal in your life before? Don’t worry this post is dedicated to one such unique animal known as Tardigrade.
