Despite the extreme temperatures and pressures, toxic minerals, and lack of sunlight that characterized the deep-sea vent ecosystem, the species living there were thriving. ... As pressure builds and the seawater warms, it begins to dissolve minerals and rise toward the surface of the crust.

How do animals survive in underwater volcanic 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 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.
Why the discovery of hydrothermal vents and chemosynthesis were so exciting to marine scientists?
The discovery of hydrothermal vents changed all that. Vast communities of animals grew big and fast in the depths! Instead of using light to create organic material to live and grow (photosynthesis), microorganisms at the bottom of the food chain at vents used chemicals such as hydrogen sulfide (chemosynthesis).
Is there life in hydrothermal vents?
The floor of the deep ocean is almost devoid of life, because little food can be found there. But around hydrothermal vents, life is abundant because food is abundant. ... These vents are the only places on Earth where the ultimate source of energy for life is not sunlight but the inorganic Earth itself.
What animals live in deep sea 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.
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.
How are deep sea vents teeming with life?
Teeming with life
Despite the absence of sunlight, all of the essential ingredients are there: heat from the Earth, mineral-rich vent fluids, and a vast universe of microbes that use chemicals produced by these volcanic systems—such as hydrogen sulfide, hydrogen, and even natural gas—as energy sources.
What is the source of food for creatures living near deep sea hydrothermal vents?
Tube Worms
Chemotrophic bacteria that convert hydrogen sulfide into organic sustenance are some of the most important organisms in the hydrothermal vent habitat. Many of the marine creatures that live near hydrothermal vents utilize these bacteria as a source of food.
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.
When did we discover deep sea hydrothermal vents Why is this date so surprising?
Scientists first discovered hydrothermal vents in 1977 while exploring an oceanic spreading ridge near the Galapagos Islands. To their amazement, the scientists also found that the hydrothermal vents were surrounded by large numbers of organisms that had never been seen before.
Why are hydrothermal vents considered one of the greatest discoveries of all time?
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.
What role do the organisms of deep sea vents play in cycling certain elements?
The organisms of deep sea hydrothermal vents are well adapted to fix carbon dioxide in an unusual range of temperatures, pressure condition, pH and metal toxicity.
Why is deep-sea vent theory a possible explanation for life on earth?
Many scientists think life got its start around 3.7 billion years ago in deep-sea hydrothermal vents. ... Somehow, the precursors of life harnessed carbon dioxide and hydrogen available in those primitive conditions to create the building blocks of life, such as amino acids and nucleotides (building blocks of DNA).
What is unusual about life and these hydrothermal vents?
Hydrothermal vents are home to unusual deep-ocean ecosystems that include giant tubeworms, large clams, beds of mussels, and many other creatures. ... A fracture zone, on the other hand, is a seismically inactive area that offsets the axis of a mid-ocean ridge.
Why did life likely start at the hydrothermal vents?
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. ...
