Tardigrada (water bears) are well known for their ability to undergo cryptobiosis and survival in extreme conditions. The best-known type of cryptobiosis for their survival is anhydrobiosis i.e. response to lack of water. In this state tardigrades are able to tolerate high pressure, very high and low temperatures, space vacuum, and high levels of UV, and ionizing radiation. These results in various ultrastructural changes in tardigrades, including in mitochondria. We analyzed the effect of different temperatures (20 Β°C, 35 Β°C, 37 Β°C, 40 Β°C and 42 Β°C) on the ultrastructure of mitochondria in the tardigrade Paramacrobiotus experimentalis Kaczmarek et al. 2020. Analyzes were conducted in active specimens, specimens in anhydrobiosis (tun), and rehydrated specimens. The analysis will provide knowledge about changes in the ultrastructure of tardigrades caused by different temperatures. Our results will also determine whether anhydrobiosis protects against temperature-induced ultrastructural changes.
