Purpose:
The results of the 2006 marine life survey of DECAPODA were recently announced. This census activity aimed at protecting marine biodiversity was started in 2000 and has been going on for six years. According to the British Times 1 1, one of the highlights of the 2007 census was the ubiquitous signs of life in the deep sea that amazed scientists. A kind of shrimp that moves freely in boiling seawater surprises scientists the most.
Scientists found this kind of shrimp, dubbed "boiling shrimp", in the deep sea about 3 kilometers from the sea level near the equator of the Atlantic Ocean. In the sea where they live, the water temperature drops to 2℃, almost close to freezing point, but the submarine crater spews water as high as 400℃ or even higher into the cold sea water, which is enough to melt the metal. The activity range of boiling shrimp is generally in the mixing zone of cold and hot water at 60℃ to 80℃, but because the vortex generated by the mixing of cold and hot water often washes the boiling shrimp away, scientists believe that boiling shrimp must resist higher temperature to survive.
What fascinates scientists most is that protein in organisms usually decomposes under the action of high temperature, so the phenomenon that boiled shrimp can survive near the crater deserves further study.
Boiled shrimp has a unique taste. According to scientists who have tasted shrimp, boiled shrimp tastes disgusting and difficult to swallow. This may be because boiling shrimp lives near the crater and accumulates a lot of chemicals such as hydrogen sulfide in its body.
Scientists haven't found out which species the boiled shrimp belongs to, but what is certain is that they are close relatives of Atlantic vent shrimp living in other cold craters. The discovery of more than 500 new species is one of the great gains of this census. For example, a squid in the middle of the Atlantic can tear its prey into pieces and swallow it. At the depth of 5,000m in Sargassum waters, there are still organisms, among which 12 species of plankton were previously unknown.
