Transcript of Hydrothermal Vent Ecosystem

Hydrothermal Vent Food Web
Brachyuran Crab
Scientific Name: Bythograca Thermydron
Microbes include Bacteria and Archaea that use Chemosynthesis to make their own food.
Tube Worm
Scientific Name: Riftia Pachyptila
Scientific Name: Bathymodiolus Thermophilus
Food Source:
Endosymbiotic relationship between bacteria living inside it
Food Source:
Endosymbiotic relationship between bacteria living inside it
Scientific Names for some bacteria:
Episilonproteo bacteria
Beggiatoa bacteria
Thiomargarita bacteria
Food Source:
mussels, microbes, tube worm, and sometimes other crabs.
Vent Shrimp
Scientific Name: Rimicaris Hybrsae
Food Source: microbes and bacteria.
Pompeii Worm
Scientific Name: Alvinella Pompejana
Food Source: microbes and bacteria.
They have a sort of symbiotic
relationship. The hairs on
it's back provide places for
bacteria to live on and the
worm eats the microbes.
Vent Ratfish
Scientific Name: Hydrolagus Colliei
Food Sources: crabs, clams, shrimp, worms, sea stars, fishes.
Dandelion Siphonophores
Scientific Name: Thermopalia Taraxaca
Food Source: this organism is known as a scavenger and will eat dead organisms and vent shrimp.
Zoarcid Fish
Scientific Name: Thermarces Cerberus
Food Source: galatheid crab, zooplankton and anything else it can catch, as it is a slow and lethargic moving predator.
Tube Dwelling Anemone
Scientific Name: Cerianthus
Food Source: vent shrimp and anything else it can capture and sting with it's tentacles.
Vent Octopus
Scientific Name: Vulcanoctopus Hydrothermalis
Food Source: zoarcid fish, galatheid crab. This organism is a top predator in the food chain and will eat almost anything.
Blind Crabs
Scientific Name: Kiwa Hirsuta
Food Source: dandelion, bacteria, deep sea worms, clams, mussels and anything else it can catch.
Food Source:
microbes, zooplankton and any animals that are smaller than itself.
Scientific Name: Munidopsis Curvirostra
Galatheid Crab
Top Consumers
Secondary Consumers
Primary Consumers
Fun Fact:
While a part of the lobster family, these organisms don't turn red when boiled.
Fun Fact:
The Tube Worms have a special hemoglobin that allows them to carry oxygen and hydrogen sulfide in their blood to allow the bacteria inside them to oxidize the hydrogen sulfide into energy.
Fun Fact:
This organism thrives 1.5 miles below the surface of the ocean.
Fun Fact:
This species of octopus doesn't have an ink sack like it's relatives, so when it feels threatened, it runs away and hides until it feels safe enough to come out.
Fun Fact:
They are also known as the blind shrimp because of their eye sight.
Fun Fact:
The tail of the Pompeii worm can be in waters as hot as 81 degrees Celsius and the head can be in water as moderate as 22 degrees Celsius.
Fun Fact:
When female Ratfish lay their eggs, they leave the babies to survive on their own.
Fun Fact:
Since these organisms are scavengers, this species is a good indicator to whether the ecosystem is alive or dead.
Fun Fact:
These fish can grow up to at least 2 feet long.
Fun Fact:
Females leave the vents to have their babies because the children can't handle the harsh heat. Usually after they breed, the mothers die.
Fun Fact:
These crabs have very short tails that are entirely hidden under the thorax.
Fun Fact:
The bacteria, like the ones found in microbes, are commonly known as extremophiles because they are adapted to survive in the harsh climate of the vent community.
Fun Fact:
Fun Fact:
Zooplankton population changes seasonally and members of the population occasionally feed on the other members belonging to the same species.
There are thousands of species of Zooplankton known to man that live in the ocean and many organisms inhabiting the hydrothermal vent ecosystem eat many of the different kinds.
Food Source: these organisms find food in the source of chemosynthetic bacteria
Food Source: would include the elements released from the vents.
Since this organism can withstand large amounts of heat, it usually resides near the opening of the vent.
Hydrothermal Vent
Vents are a crack or breakage in the Earth's surface. Seawater seeps in the cracks on the ocean floor and the magma underneath the tectonic plates heats the water and forces it upwards. The vent is formed when a jet of water comes shooting out, allowing the dissolved minerals and chemicals in the water to now separate and provide a food source for the chemosynthetic bacteria.
Energy Source
The two pictures are images of the types of vents that occur. They are called white smokers and black smokers. The colour depends on the minerals present in the vent.
Fun Fact:
There is no sunlight found at the vent ecosystems, so the organisms that live there live solely without sunlight and use a process called chemosynthesis to live.
When mussels decide they want to move within their ecosystem, they shoot out a thread kind of like how a spider shoots out a web strand. The thread sticks to a rock or hard surface and then the mussel can reel itself along the thread.
