Mussels are filter feeders that filter microscopic aquatic life, such as plankton, from the water around them. The larvae of some mussel species are temporarily parasitic.Know More
Mussels are bivalves, like clams and oysters, that live in both saltwater and freshwater habitats. A mussel feeds by filtering water through the body. Water enters through the incurrent syphon organ and moves through the body via the motion of cilia. Wastewater exits the mussel's body through the excurrent syphon. Food filters out of the water, and labial palps pass it to the mussel's mouth. A mussel's food typically consists of phytoplankton, zooplankton and algae.
The larvae of certain freshwater mussels spend a portion of their lives as a sort of parasite, living on the gills of a host fish. This does not typically harm a fish unless the larval load is extremely high.
Mussels are important indicators of the health of a waterway. Mussels also keep waterways clean of excess plankton and algae and may even filter out some harmful bacteria.
Zebra mussels are a mussel species native to eastern Europe that is invasive in many North American waterways. Like other mussels, zebra mussels are filter feeders. They inhabit waterways in numbers so great that their populations are capable of filtering the entire contents of some lakes and ponds in a single day, robbing native aquatic species of sustenance.Learn more about Marine Life
Brine shrimp eat green algae by filtering water through their legs. Members of the order Anostraca, brine shrimp are small crustaceans that live in brine pools and other inland waters featuring high salinity.Full Answer >
Seaweed absorbs nutrients from the water and utilizes energy from the sun for photosynthesis. All seaweed species are simple plants and have no use for conducting tissues or roots, although some species anchor themselves to rocks.Full Answer >
The diet of the oarfish consists of plankton, small crustaceans and small squid that they are able to strain from the water. These fish have a small mouth with no visible teeth, so they strain their food through a specially formed gill rake that can be found on the inside of their mouth.Full Answer >
Most corals feed on phytoplankton, which are plants and algae that flow through the water. Invertebrate larvae, decomposing organic matter and floating plankton are also common food sources. Bacteria from dead plant matter, mucus and other various sources is eaten by corals, and some large corals eat small fish.Full Answer >
