Thermococcus gammatolerans is the most radiation resistant organism known to man.
The resistance to ionizing radiation of T. gammatolerans is enormous. While a dose of 5 Gy is sufficient to kill a human, and a dose of 60 Gy is able to kill all cells in a colony of E. coli, Thermococcus gammatolerans can withstand doses of up to 30,000 Gy, enough to kill off an entire football stadium full of humans.
Might not be coincidence that it’s also green like the hulk. This thing is a champion among champions - makes even a super monster like Deinococcus radiodurans, capable of withstanding upto 15,000 Gy, look like a clueless kid.
Valonia ventricosa, also known as “bubble algae” and “sailors’ eyeballs”, is a species of algae found in oceans throughout the world in tropical and subtropical regions. It is one of the largest single-cell organisms.
So much life going on out there in the oceans.
