A hydrothermal vent which is also called Black Smoker is a fissure in the surface of the Earth. There are gases that rise through it, which heat the water around it. There are many such vents on Earth. If they are on land, they are usually hot springs, geysers, or fumaroles.Many archaea and bacteria live near hydrothermal vents, which are underwater. They support giant tube worms, clams and ...Online Consulting

Jun 06, 2017nbsp018332Flitting among the tube worms around hydrothermal vents are zoarcid fish, which are commonly referred to as pink vent fish due to their appearance. Surprisingly, these rayfinned marine creatures are the top predators of the marine creatures that live near hydrothermal vents, feeding on anything from mussels to smaller tube worms.Online Consulting
The chaotic physical and chemical environment at deepsea hydrothermal vents has been associated with an ecosystem with few predators, arguably allowing the habitat to provide refuge for vulnerable species. The dominance of endemic limpets with thin, opencoiled shells at north Pacific vents may support this view.Online Consulting
