Pyrolobus fumarii (Latin for "fire lobe of the chimney" [1]) is a species of archaea known for living and reproducing at extremely high temperatures that kill most organisms. [1] [2] P. fumarii is known as a hyperthermophile obligately chemolithoautotroph. In the simplest terms, this archaea grows best in warm temperatures ranging from 80 °C ...
Their "harpoon" is venomous, which assists cone snail to paralyze or kill the prey before eating it. A number of vertebrate species also make use of solid projectiles. Among birds the hornbill uses projectile motion to eat food. The hornbill's beak typically only contacts at the tip, and it has a short tongue.
When dried and frozen, Deinococcus radiodurans could survive 140,000 grays, or units of X-and gamma-ray radiation, which is 28,000 times greater than the amount of radiation that could kill a person.
Stimuli that have the potential to harm or kill demand rapid detection. This is fundamentally distinct from navigation or exploration, in terms of the timescales available for response. Most motile species harbour a form of phobic or emergency response distinct from their steady state locomotion. [129]
The comparison in the table below is only meant to give approximate indications of radioresistance for different species and should be taken with great caution. There are generally big differences in radioresistance for one species among experiments, due to the way radiation affects living tissues and to different experimental conditions.
The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...
Radiotrophic fungi are fungi that can perform the hypothetical biological process called radiosynthesis, which means using ionizing radiation as an energy source to drive metabolism. It has been claimed that radiotrophic fungi have been found in extreme environments such as in the Chernobyl Nuclear Power Plant .
Likewise, gamma radiation and X-rays were found to be high-energy electromagnetic radiation. The relationship between the types of decays also began to be examined: For example, gamma decay was almost always found to be associated with other types of decay, and occurred at about the same time, or afterwards.
