You have high risk of scabies if your skin comes in contact with the skin of a person having scabies because scabies is a contagious disease.
They dry out and not have enough water.
An animal called a 'strain 121' can survive in temperatures of 121 degrees C and can survive short periods of time of 130 degrees C. Thermophilic microorganisms have been recorded as living at temperatures as high as 250 Fahrenheit. But you'd have to be more specific if you have a particular animal in mind.
Extreme temperatures where?
It is very unlikely. Scabies Sarcoptes Scabiei is spread by human to human contact. Animal scabies can irritate humans but cannot survive long enough to cause much problem. Domestic poultry is not prone to this type of mite.
Extremophiles are organisms that survive in extremely high temperatures. This type of microbe is extremely adaptable to even the most adverse conditions and manage to thrive wherever they are. The Extremophiles' most common domain is Archaea, but they are also found in numerous other bacteria.
Sarcoptes scabei Dog Mange is the less serious, yet highly contagious, type of itch mange. Sarcoptic mange, aka "Scabies," has zoonotic potential, which means it's the mite you can get from your pet! Mange in humans is called scabies and is easier to get rid of.
There is no life. No human could survive such temperatures.
Yes, snails can survive cold temperatures. The snails will stay out until the temperature turns to freezing then they will seek shelter.
No. Many require only minimal water and very low temperatures, and many are in the middle.
