Hydrothermal vents support unique ecosystems and their communities of organisms in the deep ocean. They help regulate ocean chemistry and circulation. They also provide a laboratory in which scientists can study changes to the ocean and how life on Earth could have begun.

Why are thermal vents important?
Hydrothermal vents act as natural plumbing systems that transport heat and chemicals from the interior of the Earth and that help regulate global ocean chemistry. In the process, they accumulate vast amounts of potentially valuable minerals on the seafloor.
Why do animals live near hydrothermal vents?
Initially the temperature of the fluid released from hydrothermal vents is extreme - it can reach over 400°C. But despite the scalding heat, the environment around the vents is habitable for a range of animals. 'While these fluids are hot, they tend to cool very quickly as they mix with seawater,' explains Maggie.
What are deep sea thermal vents?
deep-sea vent, hydrothermal (hot-water) vent formed on the ocean floor when seawater circulates through hot volcanic rocks, often located where new oceanic crust is being formed. ... Vents also occur on submarine volcanoes.
How do organisms survive in deep sea vents?
Organisms that live around hydrothermal vents don't rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.
Why are hydrothermal vents important for the deep ocean ecosystem?
Hydrothermal vents support unique ecosystems and their communities of organisms in the deep ocean. They help regulate ocean chemistry and circulation. They also provide a laboratory in which scientists can study changes to the ocean and how life on Earth could have begun.
How do hydrothermal vents affect ocean chemistry?
Hydrothermal circulation at mid-ocean ridges draws in seawater, rearranges the seawater's chemical composition, and spews out chemically different fluids. The vents act as great chemical reactors that help maintain the balance of Earth's ocean chemistry.
What organism lives in hydrothermal vents?
Hydrothermal vents are home to many kinds of animals, including tubeworms, crabs, mussels, and zoarcid fish. The octopus is one of the top predators in hydrothermal vent ecosystems. Most hydrothermal vents on the Mid-Atlantic Ridge don't have tubeworms, but they do have shrimp, many of which host symbiotic bacteria.
What are vent organisms?
Discovered only in 1977, hydrothermal vents are home to dozens of previously unknown species. ... Huge red-tipped tube worms, ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme deep ocean ecosystems found near undersea volcanic chains.
How do animals survive in the ocean?
Common oceanic animal adaptations include gills, special breathing organs used by some oceanic animals like fish and crabs; blowholes, an opening on the top of the head that's used for breathing; fins, flat, wing-like structures on a fish that help it move through the water; and streamlined bodies.
What organisms live on the bottom of the ocean that surround the hydrothermal vents?
The main families of organisms found around seafloor vents are annelids, pogonophorans, gastropods, and crustaceans, with large bivalves, vestimentiferan worms, and "eyeless" shrimp making up the bulk of nonmicrobial organisms.
How did hydrothermal vents create life?
By creating protocells in hot, alkaline seawater, a research team has added to evidence that the origin of life could have been in deep-sea hydrothermal vents rather than shallow pools. ...
Which of the following organisms can survive in hot springs and deep-sea hydrothermal vents?
The archaea are the organisms that can live in hot springs and thermal vents.
Why can some bacteria live in volcanic vents?
Green sulfur bacteria are unique among hydrothermal vent bacteria because they require both chemical energy (from hydrogen sulfide) and light energy to survive.
How hot are thermal vents?
Seawater in hydrothermal vents may reach temperatures of over 700° Fahrenheit . Hot seawater in hydrothermal vents does not boil because of the extreme pressure at the depths where the vents are formed.
How do organisms that live at the bottom of the sea where there is no light obtain energy?
Obviously, organisms who live at the deep sea vents can't rely on the Sun; instead, many of them rely on the chemicals that come out of the vents—the process they use to create food is called chemosynthesis instead of photosynthesis.
