How does this organism survive in its extreme environment?
Tubeworms in a hydrothermal vent –
Tube worms are unique they have a highly vascularized red color Plume on the tip of their free end which is a kind of an organ which helps it in exchanging compounds with in the environment such as H2S, CO2, O2, These kind of tube worms actually do not have any kind of predators, very few are creatures who are found living in such depths of the ocean. When they find themselves threatened, there plume retracts into their worm’s protective tube.
Tardigrade – tardigrades can survive extreme temperatures which are above zero or also above boiling point of water, these pressures are about six times greater than those found in the deepest oceans . Tardigrades…show more content… These tubeworms get their nutrients from bacteria which are around to oxidize hydrogen sulfide. They use dissolved oxygen from the water as electron acceptor. The reaction from this provides the tube worms with energy needed for chemosynthesis .Tubeworms are really unique able to they use bacteria from which they indirectly obtain all nutrients required by them for growth from the molecules which are dissolved in water. These creatures are considered as unique because they have no digestive system but the bacteria turn oxygen, hydrogen sulfide, carbon dioxide, etc. into organic molecules on which their host worms…show more content… Tubeworms in a hydrothermal vent
These Colonies grow where hot mineral water flows out from the seafloor and undersea hot springs. Deep down where there are volcanic activity deep below the seafloor.at times these hot springs stop flowing and in that situation these colonies can die altogether. In a year or so new hot springs appear in other areas which are colonized by tubeworm larvae. http://www.extremescience.com/deep-sea-vents.htm Tardigrade- tardigrades can survive 1,000 times more radiation than other animals on the earth. High amount of lethal doses of 5,000 Gy (of gamma rays) and 6,200 Gy (of heavy ions) compared to this human can only survive 5 to 10 Gy and even this could be fatal to human beings. tardigrades can survive heated temperature for a few minutes to 151 °C (304 °F) or being chilled for days at −200 °C (-328 °F).[26] Some can even survive cooling to −272 °C (~1 degree above absolute zero or -458 °F)[27] for a few minutes. These organism can survive in these conditions up to 10 years.
