Small cute water bears, also known as Tardigrades, undergo stress testing through top scientists to study their sustainability in the environment. Tardigrades are amphibious creatures and eight-legged microscopic bears that is hard to capture with naked eyes. So let’s delve into them in detail.
What are Tardigrades?
Elaborating Tardigrades stress testing brings out a bundle of wonderful facts about these extremely cute and ubiquitous model organisms. Research suggests that Tardigrades can be an interesting study subject for the enthusiasts of aquatic animals that are spotted probably at all parts of the Earth. Even Pharmaceutical companies are eyeing the possible physical attributes and scientific formations, making them an indestructible species on the planet.
Most of the terrestrial animal species dwell on the soil, moss, leaf litter and moss. Other forms of species are found in fresh saltwater. They are also referred to as the water bears and largely resemble the eight-legged pandas. Few also term them as piglets or the pygmy rhinoceroses. Tardigrades have a peculiar microbial content making them the cutest invertebrate ever.
Reason for Stress Testing on Tardigrades
Researchers had in mind the studies of development consider Tardigrades as their first choice for stress testing purposes. The primary objective of this study is to analyse their physiological simplicity and understand their developmental cycle in-depth. These creatures have a unique pattern that differentiates them from the other organisms based on their cellular development.
Other species like the eutelic or C. elegans have a consistent cell count during their development. In contrast, the Tardigrades have around 1000 cells and are perfect educational models to learn unexplored principles of life sciences.
Crucial Facts About these Water Bears
- Tardigrades are quite transculent in nature, and they measure around 500 micrometres or half a millimetre in length. With a decent amount of light directed to them, it is possible to view them with naked eyes.
- For study purposes, scientists observe Tardigrades with the dissecting microscope with an elongated magnification of this charismatic species.
- These tiny invertebrates move around in curiosity and are slow climbers over the small bits of debris. You can relate them much similar to the snails, who are much bigger and widely known.
- Tardigrades have earned their initial name ‘Tardigrada’ with an Italian abbreviation and have a Latin meaning of ‘slow walker’. These creatures have stubby and short legs beneath their hardly visible bodies.
- Such microorganisms tend to hide their stout legs as soon as they enter their habitats. Tardigrades mainly pertain to 5 body sections, including a head, pair of legs and well-fitted claws.
- The claws of this animal seem familiar to the bearlike weapony and sharp claws. Their legs are found doing slow-motion acrobatics in water that helps them climb up their path.
- The micro beasts have similar anatomy that signifies the huge animals and a well-built digestive system and the alimentary canal. Besides, you ought to notice their oesophagus, intestine, anus and stomach through the magnifying glasses.
- Similar to humans, they also have a dorsal brain that is well-paired with the ventral nervous system. They also have an open hemocoel that helps in getting efficient nutrition without any respiratory systems.
- Tardigrades have a flexible cuticle that keeps shedding off as this microorganism grows bigger. Detailed research also suggests that tardigrades extend their cells to become bigger in size, and they peculiarly enter the development phase during summers.
Pharmaceutical companies might avail some phenomenal outcomes after the stress testing of Tardigrades and understand their survival patterns for upcoming developments. Two main classes of these species are the Heterotardigrada and the Eutardigrada. These species’ unique attributes are known as a brute or the dog-like ability to sustain in extreme conditions. On a Discovery show, these creatures were crowned as the ‘Most Extreme’ survivors putting back the penguins of the Antarctic region and even camels living in the scorching heat of desserts.
Like any other living being on this planet, these creatures can conveniently grow, eat, reproduce and even fight to enact normally in the life routines. As they have sensitivity towards the oxygen tension, they love to float in water. Stress testing them till the temperature of 150 degrees Celsius claims of their survival. They have also sustained the freezing cold of -200 degrees Celsius for almost 20 months.
Stunning facts also conclude that when tardigrades are in the cryptobiotic state, they could also possibly sustain the ultraviolet radiation of the space. There’s a lot more that could unleash after further thorough research on mysterious small bears!
