Question: What Do Deep Sea Mussels Eat?

What eats vent mussels?

Zoarcid fishThese two-foot long white fish are top predators around vents. They eat everything from tubeworms to shrimp. Despite their huge appetites, these fish are slow and lethargic. They spend a lot of time floating around clumps of tube worms and mussels.

Where are the mussels symbiotic bacteria found?

Hydrothermal vents in the deep sea are fascinating and rich habitats. Mussels, for example, thrive in this seemingly hostile environment, nourished by symbiotic bacteria inside their gills.

Do mussels eat bacteria?

Diet: Mussels filter their food out of the water. They eat algae, bacteria, and other small, organic particles filtered from the water column. Life history: The larvae of these mussels are parasites on the gills and fins of freshwater fishes, including darters, minnows and bass.

How do deep sea vents survive?

‘ The food chain at these ocean oases relies on a core process called chemosynthesis, which is carried out by bacteria. This is similar to photosynthesis used by plants on land, but instead of using light energy from the Sun, the bacteria use chemicals drawn from the vent fluid.

What eats the pink vent fish?

The vent ecosystem’s top predators are species such as octopus and Zoarcids, two-foot long fish that eat everything from tubeworms to crabs.

Do mussels do chemosynthesis?

Despite the absence of light-driven primary production in these deep-sea ecosystems, mussels succeed reaching high biomasses in these harsh conditions thanks to chemosynthetic, carbon-fixing bacterial symbionts located in their gill tissue.

What does chemosynthesis produce?

During chemosynthesis, bacteria living on the sea floor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in sea water). Pure sulfur and sulfur compounds are produced as by-products.

How do deep sea organisms get their energy?

The three main sources of energy and nutrients for deep sea communities are marine snow, whale falls, and chemosynthesis at hydrothermal vents and cold seeps.

How do organisms live in hydrothermal vents?

Organisms that live around hydrothermal vents don’t rely on sunlight and photosynthesis. Instead, bacteria and archaea use a process called chemosynthesis to convert minerals and other chemicals in the water into energy.

How long do mussels live for?

Although some mussels can live for up to 50 years, the brown mussel that we find along the east coast of SA only lives about 2 years.

How long do freshwater mussels live?

Most mussels live around 60 to 70 years in good habitat.

How long do mussels live out of water?

How long can raw mussels be left at room temperature? Bacteria grow rapidly at temperatures between 40 °F and 140 °F; mussels should be discarded if left out for more than 2 hours at room temperature and always discard if mussels are no longer alive.

Why do hydrothermal vents die?

They become inactive when seafloor-spreading moves them away from the rising magma or when they become clogged. Some vent fields may remain active for 10,000 years, but individual vents are much shorter-lived.

How old are hydrothermal vents?

Many scientists think life got its start around 3.7 billion years ago in deep-sea hydrothermal vents.

What are bacteria living in deep sea vents called?

There may be aproximately ten to twenty thousand species of bacteria and archaea that roam the deep sea vents (Botos). Major types of bacteria that live near these vents are mesophilic sulfur bacteria. These bacteria are able to achieve high biomass densities due to their unique physiological adaptations.
