Hydrothermal vent dwellers carry chemosynthetic bacteria usually located in their tissue or in their gills.
Deep sea ecology: hydrothermal vents and cold seeps | …
Travel to a world of perpetual night--the deep ocean hydrothermal vents near the Galapagos Rift where life thrives around superheated water spewing from deep inside the Earth. Discovered only in 1977, are home to dozens of previously unknown species. Huge red-tipped , ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme found near undersea volcanic chains. How is life possible here? In a process called chemosynthesis, microbes at the base of the foodchain convert chemicals from the vents into usable energy. See closeup footage of hydrothermal vents and species in this clip from the IMAX film "Volcanoes of the Deep."
Tubeworms and huge clams are the most distinctive inhabitants of Pacific Ocean vent sites, while eyeless shrimp are found only at vents in the Atlantic Ocean.
The first hydrothermal vent was discovered in 1977.
Hydrothermal Vents - Chemosynthesis
Scientists have long assumed that life on Earth originated in the oceans and the recentdiscovery of communities of microbes and animals that congregate around hot spring ventsin the deep sea has buoyed speculation that the earliest life on our planet may haveoccurred in the depths of the ocean in the absence of sunlight. Deep Sea hot springvents are places on the seafloor where hot water exits the ocean crust and comes to thesurface. The hot water forms when seawater is heated in young ocean crust (usuallyclose to spreading centers and areas of volcanic activity). Associated with thesevents are living communities that exist thousands of meters beneath the surface ofthe sea, first discovered them in the late 1970's. Up to that time it had alwaysbeen assumed that life required sunlight, but we now know the communities that live nearthese deep sea vents can exist on thermal and chemical energy provided by the vent. Thus,there life does not necessarily need sunlight and photosynthesis to prosper.
Although much of the life on this planet relies on photosynthesis in one way or another, there is another form of synthesis that is equally as important, chemosynthesis.
The deep sea is considered the largest, yet, least-known habitat on earth and covers about two-thirds of the earth.
Life in extreme environments: Hydrothermal vents
New Scientific Discoveries
Scientists are particularly interested in bacteria from hydrothermal vents because these microscopic organisms possess enzymes that can withstand high temperature and pressure, giving them many valuable uses in industry.
These bacteria convert the chemicals that shoot out of the hydrothermal vents into food for the worm.
Since a tubeworm has no mouth, how do bacteria enter the worm?

"Chemosynthesis and Hydrothermal Vent Life."
Without chemosynthesis, most animals near hydrothermal vents would not be able to live.
Chemosynthesis can only occur where there is lack of sunlight with the proper bacteria and chemicals needed to perform chemosynthesis.
Chemosynthesis does not occur in the water near hydrothermal vents, it occurs within the actual animal itself.

Hydrothermal Vent Octopus
Japanese Spider Crab
Giant tube worms-Forminifera
Mutualism: Giant tube worms and Chemosynthetic bacteria.
Predation: Hydrothermal vent octopus and Japanese spider crab.
Worms provide home, bacteria provides food.
Octopus feeds on the crab.
Parasitism: Many protists to the other animals.
Protists parasite onto the other animals often eventually killing them.
Intra-specific competition: Bacterias
Many bacterias must compete for the chemicals coming out of the vent,
or in some cases for space to live inside animals like the Giant tube worm.
Hydrothermal Vent Octopus
Temperature averages/ranges: Up to 400 degrees Celsius,
average range 300-400 degrees Celsius at the vents,
surrounding water around 2-4 degrees Celsius
Seasonal Changes: consistent year-round.
Geologic Processes: Shifting tectonic plates make cracks
in the crust if the earth allowing geysers of rich mineral water to escape.
Chemical Processes: pH can be as low as 5
-Black smokers: High in sulfur, high temperatures.

In order for one to understand the chemosynthesis, you must know the why, where and how of it.
Animals found near hydrothermal vents have very few options for food.
