Antarctica-New Discoveries

The Earth secretly holds loads of information which gets released when the time seems to be appropriate for us to know. Here is a snippet of what researchers have recently been discovered in Antarctica.
585 new species of crustaceans and hundreds of new worms have been discovered in the dark waters around Antarctica, suggesting these depths may have been the source of much marine life, European researchers reported on Wednesday.
Samples were scooped from as deep as 6 348m, where a team of researches found unexpectedly rich diversity of animal life. Many belong to species found around the world, notably in the Arctic, while others appear to be unique to the deepest Antarctic waters.
The unique species tend to be the kind that does not spread easily, which suggests the deep, cold southern oceans may have been the source of many types of marine life. The Antarctic deep sea is potentially the cradle of life of the global marine species. The scientists’ research results challenge suggestions that the deep sea diversity in the Southern Ocean is poor. They now have a better
understanding in the evolution of the marine species and how they can adapt to changes in climate and environments.
Among the new creatures they documented are a gourd-shaped carnivorous sponge called Chondrocladia; free-swimming worms and 674 species of isopod, a diverse order of crustaceans that includes woodlice, also commonly called pillbugs, sea lice or sea centipedes. Of the isopod crustaceans, 585 species had never been seen before.
Between 2002 and 2005, researchers sampled water and the sediment from 774m to 6 348m in the deep Weddell Sea and adjacent areas. Their catch was surprisingly rich and what was once thought to be a featureless abyss is in fact a dynamic, variable and biologically rich environment.
The researchers said the Weddell Sea is an important source of deep water for the rest of the ocean. Species can enter the depths of the Weddell sea from shallower continental shelves.
Animals that spread easily, such as the single-celled Foraminifera, were similar to those found in other oceans and the isopods, ostracods (seed shrimp) and nematodes, which are poor dispersers, include many species currently known only from the Southern Ocean.

    Good afternoon Kate. I’m sure there are so many more creatures on this planet, still waiting to be discovered. Fascinating subject.
    Enjoy the rest of the week   🙂

    Hello Kate
     
    This is all very interesting but have you ever thought your ancestors and my ancestors everyone of them lived long enough to reproduce right back to as far a a single cell, obvious but amazing
     
    Love Suki x

    Hi Kate,
     
    All those things and Creatures could not have been engineered by themselves or by some lucky fortunate events !  I really believe that the Great Creator whom we call GOD will always amaze us with new discoveries !
     
    The wonder is everywhere.
     
    Kate, keep enriching us with your page.
     
    Take care,
    Love.

    Hi Kate,
    very interesting piece, apparently we know more about space than we do about the bottom of the sea, amazing…
    All these different forms of life so far down, makes you wonder what else is down there.
    6300m is a hell of a long way down, the pressure must have been huge, apart from the lack of light, I know I like to dive, but I think thats just a bit too deep.
    have a great weekend & I hope the weather stays good for you
    take care,
    see you soon
    Woof woof x

    Hi Kategood article. I have always been fascinated by the antarctic since reading at school about arctic exploration in the early 20th Century. Would love to go there for a visit some day.hope your having a good week !Peter
