The hydrothermal vents are recognized as a type of chemosynthetic based ecosystems (CBE) where primary productivity is fuelled by chemical compounds as energy sources instead of light (chemoautotrophy). [28] Hydrothermal vent communities are able to sustain such vast amounts of life because vent organisms depend on chemosynthetic bacteria for food.
Kiwa tyleri, the Hoff crab, is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica. [1] The crustacean was given its English nickname in 2010 by UK deep-sea scientists aboard the RRS James Cook, owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David ...
Life flourishes around the vents - including giant tubeworms reaching lengths of 10 feet (3 meters), mussels, crabs, shrimp, fish and other organisms beautifully adapted to this extreme environment.
In 1980 Daniel Desbruyères and Lucien Laubier, just few years after the discovery of the first hydrothermal vent system, identified one of the most heat-tolerant animals on Earth — Alvinella pompejana, the Pompeii worm. [1] It was described as a deep-sea polychaete that resides in tubes near hydrothermal vents, along the seafloor.
Lost City and other hydrothermal vent systems support vastly different lifeforms due to Lost City's unique chemistry. A variety of microorganisms live in, on, and around the vents. Methanosarcinales-like archaea form thick biofilms inside the vents where they subsist on hydrogen and methane; bacteria related to the Bacillota also live inside ...
It was first discovered in 1997 in a black smoker hydrothermal vent at the Mid-Atlantic Ridge, setting the upper-temperature threshold for known life to exist at 113 °C (235.4 °F) with an optimal temperature of 106 °C. [1] This species "freezes" or solidifies and ceases growth at temperatures of 90 °C (194 °F) and below. [3]
Vulcanoctopus hydrothermalis, also known as the vent octopus, is a small benthic octopus endemic to hydrothermal vents. [1] It is the only known species of the genus Vulcanoctopus . This vent octopus is endemic to the hydrothermal vent habitat that is located in the East Pacific Rise.
The hydrothermal vents where these crabs live are typically short lived, lasting from 10 to 100 years. These are extreme environments, with high temperatures, high concentrations of sulphides, heavy metals, carbon dioxide and an acidic environment. [8] At this depth there is also limited access to light making photosynthesis nearly impossible.
