Microorganisms that grow in impossible conditions

Extremophiles

Microorganisms that prefer to grow in those conditions where life is impractical are called extremophiles.

No doubt, our earth is full of diversity in both flora and fauna, but in earlier times, it was considered silly to expect that any organism could flourish in so tough conditions, but fact is fact and it is true that there are organisms that are able to live at-
  1. Extremely high temperature (Thermophile or Hyperthermophile)
  2. High pressure (Piezophile)
  3. Highly acidic atmosphere (Acidophile)
  4. Highly basic atmosphere(Alkaliphile)
  5. High concentration of heavy metal in the solution (Metallotolrant)
  6. Can resist high levels of ionizing radiations (Radioresistant)
  7. Remain alive from extremely long times under the rocks at low temperature (Cryophile or Polycryophile)
  8. High concentrations of salt (halophile)
  9. High concentrations of sugar (Osmophile)
  10. Polyextremophile, which are capable of growing in various extremophile conditions
  11. Thermoacidophile who can live at high extreme temperature and high acidity
  12. Grow in oxygen less atmosphere (anaerobe)
  13. Lithoautotroph, which live on the carbon extracted from CO2 and exergonic inorganic oxidation
  14. Nutrition less atmosphere (Oligotroph)
  15. Extremely dry conditions (Xerophile)

These facts show that it is not surprising to find some type of microorganism at a place where everything dies.

Ceramic House, Colombia

Image
  Ceramic House, Colombia This is a Ceramic house designed and built by Octavio Mendoza in Colombia. The house looks comical in shape and is very strong. It is built in the same way as a brick or mud utensils are made, by first moulding a desired shape out of mud, allowing it to drain in sunlight for proper time and finally backing it in intense heat. The houses built in this style has a very special feature that it has pores inside its walls which occur when water is evaporated on heating and space is left voided in the forms of pores that acts as thin capillaries. Due to this the house cools automatically in summers and is earthquake proof, being made of a single brick. The only drawback is that it is difficult to build if levels are required and repair and renovations weakens the house. Also there are various chances of errors since larger voids can cause a poor quality house.

Japanese spider crab: Strange Species

Image
The Japanese spider crab It is an orange colored crab which has the longest leg span among any arthropod. The length of the legs from toe to toe may reach up to 3.8 meters and its body may grow up to 40 cm. the total weight of the whole adult crab is about 19 kg. It is a species of marine crab that live in the water bodies and costs of japan. They face a little bit of fishery, which led to the decline in their number and was preserved to its present status. They are mostly found in the southern cost of japan and adults may be easily found at the depths of 600 meters. They like to live in the holes or vents in the bed of the ocean. The larva of Japanese spider crab is carried by the female for around 70 days and when born, larva is in transparent state. The Japanese spider crab feeds both on aquatic plants and animals. Due to their long and strong legs they are dangerous and look strange in appearance too. In many parts of japan, it is also considered as delight on the dini...

Narwhal : Strange Species

Image
Narwhal A narwhal also known as narwhale is found around the arctic continent. It has a long straight helical tusk which exceeds the length of whole body with age. The tusk keeps growing for the whole life and may reach up to 5.5 meters. This special feature of narwhal is actually an elongated upper left canine in males. Generally females don’t grow tusks but a very small number of females too have elongated tusks which are generally smaller than those constituted by males. Most of the males have only one tusk but there are exceptions too. One in 500 narwhals is reported to have two tusks which is the result of elongation of the upper right tusk. The right tusk is always smaller and less straight then the left one. The average length of a male narwhal is about 4.1 meters which is larger than an average female (3.5 meters). Males attain puberty at about 11 to 13 years of age and females reach sexual maturity at about 5 to 8 years of age. The helical tusk of narwhal is holl...
