8 most tenacious creatures on Earth

December 3, 2021 by Posted in: Lyrics

Nature has created unique organisms, the endurance of which is simply amazing. They are able to survive in the most unusual conditions: to survive extreme temperatures, climate change, huge doses of radiation, as well as prolonged absence of air, water and food.

Tardigrades are a type of microscopic invertebrate close to arthropods. Some of the toughest creatures on our planet. They survive for more than a hundred years without water, are able to survive at -271 ° C in liquid helium and at + 100 ° C in boiling water, withstand a 1000 times higher dose of radiation than humans, and even stay in outer space. Tardigrades survive mainly due to the so-called anhydrobiosis, drying. When dry, they draw the limbs into the body, decrease in volume and take the shape of a barrel. The surface is covered with a wax shell that prevents evaporation © Youtube screenshot

Deinococcus radiodurans bacteria. It is widely known for its high resistance to radiation, being one of the most radiation-resistant organisms in the world. D. radiodurans can survive up to 10,000 grays © Commons.wikimedia.org

Lang lungfish. In fact, it is a transitional link from ordinary fish to amphibians. Has at its disposal both gills and lungs. During periods of drought, it is capable of burrowing in mud and hibernating, doing without any nutrients © www.globallookpress.com

Hydra. The secret of the hydra's phenomenal vitality lies in its high regeneration capacity. All cells in her body are constantly renewed, and damaged parts are replaced with new ones. This eliminates the accumulation of destructive substances and genomic defects. To completely restore the body of a hydra, you will need only 1/200 of its part or even a suspension of cells © Commons.wikimedia.org

The tree branch is the largest insect found in New Zealand. The length of the vet is about 10 cm, and the weight reaches 85 g. Due to the fact that the blood of this insect contains a special protein that excludes blood clotting, the tree vet is able to withstand the lowest temperatures. It is noteworthy that during periods of such “hibernation” the brain and heart of these insects is turned off. But, as soon as they “thaw out”, all organs begin to work again © Commons.wikimedia.org

The immortal jellyfish is the only creature on the planet that can live forever. After the Immortal Jellyfish reaches puberty, it returns to its initial polyp stage and begins to mature again. Moreover, this process in a jellyfish can be endless, its life cycle can repeat an unlimited number of times © Commons.wikimedia.org

Cockroach. It has been experimentally confirmed that cockroaches can live without a head for several weeks. The blood circulation process of cockroaches is not controlled by the brain, they breathe through small holes throughout the body, and on previously eaten food supplies they can exist for a long time. In the absence of a brain, the main functions of the cockroach's nervous system are taken over by ganglion cells, which are located in each lobe of the body © Commons.wikimedia.org

Vestimentifer is a recently discovered class of the Pogonophore type. Vestimentifera are characterized by the absence of intestines and mouths, have a specific organ – a trophosome, containing intracellular symbiotic bacteria, to which the circulatory system of the worm delivers hydrogen sulfide from mineral underwater springs. These two-meter worms live on the seabed in impenetrable darkness at a pressure of about 260 atmospheres. They live in the ocean near the faults of geological plates, from where the water heated to +400 ° С, saturated with hydrogen sulfide beats © www.globallookpress.com
