The Only Animal That Can Survive The Pressure of Space

These microscopic water-dwelling animals are found everywhere in the world. They are mostly found in Volcanoes, The Antarctica, Mountaintops, and Tropical Forests, rivers, and the deep sea.  What amazes scientists today about this creature is the fact that even though it seems to be a weak, tiny eight-legged animal which can only be seen under a microscope, It is, in fact, the most indestructible animal to exist. This animal is the Tardigrade, or commonly known as the Water Bear. Once a group of dehydrated Tardigrades was taken from a museum sample of dried moss and they were over 100 years old and brought back to life when hydrated. Tardigrades can live up to 30 years without food or water.


The largest this animal can get is approximately 1.5mm


Tardigrades are the only creatures found to survive in the vacuum pressure of space. If we humans went into space without protection we would die straight away. Scientists attached a group of thousand Tardigrades to a satellite and sent them over to space and when they were returned, surprisingly they were still alive. Some females even laid eggs and the hatchlings were healthy. This raises the question, could there be life on other planets besides earth? after all, there are 100 billion planets in our solar system alone and are approximately two trillion galaxies in our entire universe. Think about how many planets there may be in one of every two trillion galaxies in the entire universe. Surely we can’t be alone, can we? Anything is possible but we won’t truly ever know until we discover.

This Wood frog can survive winter completely frozen into ice. Once it melts during spring, the freeze doesn’t seem to have had any effect on it.

Tardigrades can withstand boiling temperatures of 150° C, and temperatures below  -200°C according to researchers. These animals, no matter what you do, whether you boil them, step on them, freeze them, deprive them of food or water, they will still survive. In fact, researchers say that the tardigrade can even survive a meteor impact!


These animals are said to be found almost everywhere, even as far as some of the vegetables we eat or the water we drink. However, they don’t survive the stomach acid when they get to our stomachs so we can be somewhat thankful for that. Tardigrades survive anything by radiation, pressure, toxins, temperature, dehydration, and outer space, but they can’t survive acidic environments.


Kangaroo Rat doesn’t drink water, no matter how hot and dry the land is. They feed on seeds that are dry but they obtain the water by the metallic oxidation in the seeds.

They feed on plants, bacteria, and sometimes even their own species. It is researched that each group of tardigrades are either carnivorous, omnivorous or phytophagous (feed entirely on plants).
