Iliffe and Brankovits haven't zeroed in on what kinds of chemosynthetic bacteria actually exist there, or what their food sources could be — methane, hydrogen sulfide and ammonia are all potential candidates.

An avid fisherman, he earned three degrees in geosciences from the University of Texas, Dallas, with his 1995 doctoral dissertation titled «Geological Controls on the Distribution of Chemosynthetic Organisms in the Gulf of Mexico.»

This study also provides the first identification and description, to our knowledge, of high - biomass hydrothermal - vent - endemic chemosynthetic communities in the Southern Ocean.

Pohlman believed chemosynthetic bacteria, like the kinds found around deep - ocean hydrothermal vents, must be the answer.

One was Hydrate Ridge, selected for its large methane deposits and the unusual chemosynthetic organisms that thrive on top of them.

Professor Qian said, «The study has provided genomic resources for understanding how the deep - sea mussel has adapted to the abiotic stresses and lack of photosynthesis - derived food in the deep - sea chemosynthetic environment.

Brightly colored 7 - foot tube worms thrive near deep - sea hydrothermal vents and derive their energy from chemosynthetic bacteria.

Biologists were surprised to discover that the ecosystems found on the ocean floor along these mid-ocean ridges, consisting of complex organisms like tube worms, clams, and crabs, were dependent for their food on thermophilic chemosynthetic bacteria, which produced organic compounds using the oxidation of inorganic molecules as an energy source, instead of sunlight.

Chemosynthetic symbioses evolved independently multiple times in at least nine animal phyla and from at least 12 lineages of free - living bacteria.

Exploration of deep - sea hydrothermal vents in other sectors of the Southern Ocean, such as the Pacific - Antarctic Ridge [16], are likely to reveal further chemosynthetic communities.

[13] Volcanic minerals found in lava tubes could provide a rich source of nutrients to chemosynthetic organisms.

In the vicinity of these vents, where temperatures hover at a cozy 30 degrees Celsius, thick mats of chemosynthetic bacteria convert vent chemicals into energy, and in turn support colonies of giant tube worms, huge beds of mussels and a variety of crustaceans.

The base of their food chain was not plants that captured the energy of the sun but chemosynthetic bacteria that captured the energy of the volcano.

These chemosynthetic ecosystems are now recognized to be just as important to marine biodiversity as the organisms relying on photosynthesis.

We show through molecular, behavioral, and morphological analysis that this species farms its chemosynthetic bacteria in a novel form of symbiosis.

The microbes (bacteria and Archaea) which form the base of the food chain are chemosynthetic, using energy from hydrogen sulfide in the vent fluid, and oxygen and carbon dioxide from the seawater, to create simple sugars.

Riftia lacks (as an adult) a mouth and gut, is sessile, and has acquired a chemosynthetic partner — all traits that enable Riftia to thrive in what seems to be an inconceivably hostile environment.

The chemosynthetic ecosystems hosted by these vents are dominated by a new yeti crab (Kiwa n. sp.), stalked barnacles, limpets, peltospiroid gastropods, anemones, and a predatory sea star.
