Hungry Dwellers of the Pacific and Atlantic Hydrothermal Vents
Why It Matters
Atlantic Top Order Carnivores
Atlantic 1st Order Carnivores
Atlantic Primary Consumers
Pacific Carnivore
Pacific primary consumers
Primary Producers
They are natural plumbing systems that transport heat and chemicals from the interior of the Earth and that help regulate global ocean chemistry.
Exhibit extreme adaptability of life, may also indicate towards origins of early life
Potential for seafloor mining from mineral resources
Alcanivorax borkumensis: bacteria that can metabolically break down crude oil. Used in Gulf Oil Spill.
Thermus aquaticus: Bacteria with Taq Polmerase
Scaly foot gastropod: The United States military is currently funding research on the armor of the snail in hopes of developing insights into new military armor designs
The dissolved iron that is released from some Mid-Atlantic vents is important for maintaining plankton health, as it is a limiting factor for plankton development.
Abiotic Factors
Sunlight: NONE! =O
Depth: 3000-4000 meters
Temperature: about 2 degrees Celcius, then about 400 at the vents (300-464)
pH Levels: very acidic: ranges from 2.8-4
Pressure: 300 atm
Salinity: 3.5%
Oxygen: 4.87-6.060 ml/l
CO2 levels: 4-215 mmol/kg
H2S: 2.3mM
Sodium 537 mM
Calcium 636 mM
Dissolved Hydrogen: .1-50 mmol/kg
CH4: .05 - 4.5 mmol/Kg
Chemoautotrophic bacteria use the chemical energy generated by mixing the reduced chemicals in hydrothermal fluids with deep-ocean ambient seawater to fix inorganic carbon and produce biomass. They often use Sulfides and Methanes as inorganic sources.

Methanocaldococcus jannaschii (1)
Desulfonauticus submarinus
Candidatus Arcobacter sulfidicus (2)
Desulfovibrio vulgaris
Desulfovibrio gigas
Desulfobacterium autotrophicum Desulfobacter latus
Primary Producers

Riftia pachyptila

Alvinella pompeiana (AKA Pompeii worm): grey "fur" is actually bacteria. (Desulfovibrio vulgaris, Desulfovibrio gigas, Desulfobacterium autotrophicum, and Desulfobacter latus)
Primary Consumers: Pacific
Gastropod: Crysomallon squamiferum (Scaly foot Gastropod)

Limpet: Lepetodrilus
Clam: Vescomyid Clams: Calyptogena magnifica

Bathymodiolid Mussels

Pacific 1st Order Carnivores
Fish: Zoarcid Fish: Thermarces cerberus

Crab: Brachyuran crabs
Pacific Primary Consumers
Thymopides laurentae
Octopus: Grimpoteuthis
aka DUMBO!! =D
Rimicaris aff. exoculata
Bathymodiolus puteoserpentis
Branchipolynoe seepensis
Lucernaria janetae
Shrimp: Alvinocaris lusca
Mirocaris fortunata
