creatures of the deep crack

Whilst humans need their air to contain 21 oxygen, nematodes are not so picky and can do just fine with as little.5.
There were no obvious cracks in the stalactites, so the worms must have become trapped inside them when they first formed.
These species have evidently evolved to be quite flexible about where they live.
So it was trying not to be seen, basically.The stalactite water is salty enough for them, but the mine is almost in the centre of South Africa so the nearest ocean is hundreds of miles away.View image of A nematode on biofilm (Credit: Gaetan Borgonie/Nature Communications).Over time, the rim of the vent is built up into a tall, chimney-like structure.Aquatilis is a common freshwater nematode The low oxygen levels do not bother the worms.The deep sea is the largest ecosystem on earth, plunging to more than 37,000 feet below sea level at the Marianas Trench in the Pacific.So he teamed up with.Small shrimps and crabs feed on the tube worms.Aquatilis is a common freshwater nematode.This video shows the conditions in which the nematodes are living.He found 20 nematodes living inside stalactites hanging from the ceilings hp probook 4525s wireless drivers windows 7 of mine tunnels In 2013, a small snail with a translucent shell was found living almost.6 miles (1km) war and peace tolstoy ebook below ground in a Croatian cave system that includes some of the deepest caves.One scientist thought differently.On it's way back up through the cracks and fissures through which it fell, the hot water dissolves minerals and other chemicals from the rock.Whatever led to the worms' exodus from the surface, they have no reason to go back.The plants, in turn, provide food for countless species of animals in a complex web of life.The gooey biofilms have attached themselves to the man-made boreholes.
A large number of strange and wondrous creatures have been found at these vent sites.
The Challenger Expedition, an around-the-world oceanographic study led by Scottish naturalist Charles Wyville Thomson in the 1870s, trawled as deep as 26,000 feet and pulled up more than 4,000 unknown species.
