How are living things that exist in ocean vents different from other life forms?

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.

What makes life in hydrothermal vents unique?

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 type of life forms do the vents support?

Chemosynthetic bacteria and archaea form the base of the food chain, supporting diverse organisms, including giant tube worms, clams, limpets and shrimp.

What types of life forms can be found near sea vents?

Animals such as scaly-foot gastropods (Chrysomallon squamiferum) and yeti crabs (Kiwa species) have only been recorded at hydrothermal vents. Large colonies of vent mussels and tube worms can also be found living there. In 1980, the Pompeii worm (Alvinella pompejana) was identified living on the sides of vent chimneys.

How did life form in hydrothermal vents?

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).

Why is it so unusual that life is found near these 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 organisms live 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.

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 do deep sea vents form?

Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents.

Can anything survive in around a hydrothermal vent?

Most bacteria and archaea cannot survive in the superheated hydrothermal fluids of the chimneys or “black smokers.” But hydrothermal microorganisms are able to thrive just outside the hottest waters, in the temperature gradients that form between the hot venting fluid and cold seawater.

Where are vents found?

Since 1977, many vent sites have been discovered at mid-ocean ridges in the Atlantic, Pacific and Indian Oceans.

Could life have survived near the ocean floor on ancient Earth?

Could life have survived near the ocean floor in ancient Earth? Yes. There is enough heat, food and energy to sustain life.

Did sea vents come from 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. ... Some of the world's oldest fossils, discovered by a UCL-led team, originated in such underwater vents.

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.

Why are hydrothermal vents important to humans?

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. ... Learning about these organisms can teach us about the evolution of life on Earth and the possibility of life elsewhere in the solar system and the universe.
