an opening in the sea floor occurring near spreading centers in the deep-sea, from which very hot, mineral-rich water from the earth's interior is released. Precipitation of these minerals in the cold water of the deep sea leads to the formation of tall 'chimneys', or black smokers. Vents are home to many unusual creatures, many of which use chemos...
