Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions — such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation — that would quickly kill most other known forms of life.

Can tardigrades live in humans?
No, at least not to humans. ... They cannot survive the trip through the human digestive tract since our stomach acid disintegrates the flesh of the tardigrade without much trouble, so eating one wouldn't do any harm.
Are tardigrades immortal?
Their life is not really known, however, tardigrades are able to stop their metabolism and become immortal (state cryptobiosis). ... Tardigrades were found in an ice sheet 2,000 years and came back to life. This form of resistance allows it to suspend time, but also to survive extreme temperatures.
What creature survived being frozen for 30 years?
In 2016, a group of Japanese scientists successfully revived another resilient animal — the tardigrade, also known as a water bear — after 30 years of cryptobiosis, or suspended animation prompted by freezing, desiccation or other adverse conditions.
What can tardigrades survive?
Tardigrades, also known as water bears, are hardy life forms that can survive extreme temperatures—from volcanic vents on the ocean floor to the frigid climes of Antarctica. The microscopic organism can also resist the vacuum of space and lethal doses of radiation, reports Jonathan O'Callaghan for Science.
Can a Tardigrade survive a nuke?
The Tardigrade
They can be squished, broiled, and even be killed and stay dead for more than 10 years, and then be brought back to life. They're amazing and put most creatures to shame. They survive a large amount of radiation and do not absorb much in the first place.
Do water bears have brains?
Tardigrades have a dorsal brain atop a paired ventral nervous system. (Humans have a dorsal brain and a single dorsal nervous system.) The body cavity of tardigrades is an open hemocoel that touches every cell, allowing efficient nutrition and gas exchange with no need for circulatory or respiratory systems.
What animal is immortal?
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
How old is the oldest Tardigrade?
The oldest remains of modern tardigrades are those of Milnesium swolenskyi, belonging to the living genus Milnesium known from a Late Cretaceous (Turonian) aged specimen of New Jersey amber, around 90 million years old.
What does a Tardigrade eat?
Most tardigrades eat algae and flowering plants, piercing plant cells and sucking out their contents though their tube-shaped mouths.
Has anyone ever been unfrozen?
Since we have no technology that can reverse death yet, no we haven't unfrozen someone and resuscitated them from intentional cryogenic freezing. However, "unintentional cryogenic" freezing happens in accidents in cold weather climates and such.
What is a tun Tardigrade?
The most remarkable feature of the tardigrades is their ability to withstand extremely low temperatures and desiccation (extreme drying). Under unfavourable conditions, they go into a state of suspended animation called the “tun” state—in which the body dries out and appears as a lifeless ball (or tun).
How big can a water bear get?
Water bears can range from 0.002 to 0.05 inches (0.05 to 1.2 millimeters) long, but they usually don't get any bigger than 0.04 inches (1 mm) long, according to the World Tardigrada Database.
Can a Tardigrade survive a bullet?
When shooting the bullets into a sand target several meters away, the researchers found the creatures could survive impacts up to about 900 meters per second (or about 3000 kilometers per hour), and momentary shock pressures up to a limit of 1.14 gigapascals (GPa), they report this month in Astrobiology.
Do water bears still exist?
Around 1,300 species of tardigrades are found worldwide. Considered aquatic because they require a thin layer of water around their bodies to prevent dehydration, they've also been observed in all kinds of environments, from the deep sea to sand dunes.
Can a water bear survive the sun?
Although tardigrades are resilient creatures, they would not be able to survive on the sun, where temperatures can reach over 5,000 degrees Celcius.
