What are the Harshest Places on Earth in which Life Still Exists?

Question

What are the Harshest Places on Earth in which Life Still Exists? Please name a few AND a few organisms that live in each of the places that you named (something like antartica or those "vents" at the bottom of the ocean).
As usual the best answer will receive 10 points!!!

Answer 1

Many organisms exist at very high temperatures deep in the ocean, next to volcanic vents. Conversely, some manage to survive inside ice in small bubbles of liquid water. Some organisms, such as Deinococcus radiodurans, can survive all sorts of punishment including freezing and vacuum, and even live within nuclear reactors. Do a search for "extremophiles" for more examples, but D. radiodurans is probably the best example.

Answer 2

Socotra which is part of a group of 4 islands, has been geographically isolated from mainland Africa for the last 6 or 7 million years. Like the Galapagos Islands, this island is teeming with 700 extremely rare species of flora and fauna, a full 1/3 of which are endemic, i.e. found nowhere else on Earth. The climate is harsh, hot and dry, and yet - the most amazing plant life thrives there. Situated in the Indian Ocean 250 km from Somalia and 340 km from Yemen, the wide sandy beaches rise to limestone plateaus full of caves (some 7 kilometers in length) and mountains up to 1525 meters high. Also found in Socotra's landscape is the ever-strange and extremely rare Cucumber Tree (dendrosicyos socotranum). The Dragon's Blood Tree, has branches that spread out into the sky and from below appear to hover over the landscape like so many flying saucers... and from above they have a distinct mushroom look. they are a source of valuable resin for varnishes, dyes, and "cure-all" medicine.

Getting around can be a challenge, as there are almost no roads. Despite the fact that this island has around 40,000 inhabitants, the Yemeni govenment put in the first roads just 2 years ago - after negotiations with UNESCO, which has declared this island a World Natural Heritage Site.

Answer 3

quite a few human beings at NASA did no longer think of bacteria from the Moon could extremely be a possibility, yet different government companies and different international places and the regularly occurring public had expressed concerns so NASA desperate to have the quarantine just to be on the risk-free side and shop all of us calm. Astronauts getting back from lunar orbit (Apollos 8 and 10) weren't quarantined. they only did this for the 1st 3 touchdown flights, Apollos 11, 12, and 14 (the Apollo 13 team weren't quarantined because of the fact they did no longer land on the Moon so they weren't uncovered to Moon dirt or something). The crews of Apollo 15, sixteen and 17 weren't quarantined.

Answer 4

Examples of archea:

halopiles (genus Halobacterium) live in extremely salty environments like salt lakes.

Methanopyrus kandleri lives at a temp of 252 F

Picrophilus torridus lives at PH 0

Answer 5

Your stomach.

The prokaryotes that cause ulcers.
