Zooplankton



Zooplankton are tiny animals that are found in most aquatic ecosystems and are a key component to any water food web.

BlogWork
Go to this website and research one of the types of zooplankton listed (example: nanoplanktonic flagellates or phylum rotifera. Write a detailed paragraph about this type of organism.

Cnidarians
Cnidarians is a phylum that has colonial siphonophores and the scyphozoans—also known as the true jellyfish. They have a lot in common. They are both predators with stinging tentacles that can paralyze their prey. You wouldn’t often find these organisms in fresh water. They are usually found in the ocean at the near surface. Comb jellies or ctenophores were previously classified under Cnidarians but have recently been distinguished from other jellyfish because they lack the characteristic stinging cells of other jellyfish known as nematocysts. These organisms keep the copepod zooplankton population under control

Copepods
It is a macrozooplankton it lives in the fresh waters. they are not drifters this means that they do not float around and go with the flow. they use their antennas and there chest to swim. The copepods eat phytoplankton and other zooplankton if it the other plankton is smaller.

krill is a norwegin word that literaly means whale food.As ther name implies their eaten by whales, and are whales main food source. They can grow up to 3cm long and like every other marine animals they have been over fished. Its mosstly used for fish food, but is also consumed by humans in some asian countries. Though not really tastey ther great for you.Ther full of omega-3 fatty acids.

The polychaeta is a type of zooplankton that can also be referred to as a bristle worm. This is due to their unique physical attribute. Polychaeta are in a similar shape to worms, and therefore have body divided into sections. Each one of these areas has extensions that sprout tiny spikes made of chitin, giving them there name. There are over ten thousands different species of polychaeta, and most live in marine areas. Lugworm, sandworm and clam worm are all polychaeta.

All ZooPlankton are incredibly small. There are many types of zooplankton including nanoplanktonic, flagelletes, and everyones favorite phylum rotifera. Nanoplanktonic Flagellates task is to control the population of bacteria, phylum rotifera are characterized by not being able to move and also being able to produce asexualy.

Copepods are crustaceans. They make up most of the macrozooplankton in aquatic ecosystems. They swim by moving their antenna and the front part of their body. Their diet consists of phytoplankton and detritus. They also eat other zooplankton.

Chaetognatha A.K.A. Arrow worms are mostly transparent and can be found worldwide. These worms are approximately 3cm long and also have fins on their bodies.

Phylum Rotifera is mostly found in freshwater. Most of them can't move. They eat detritus, protozoa, algae, and other Rotifers. They don't need another Rotifer to reproduce. When the conditioon in the area is bad, they reproduce sexually.

One type of zooplankton is called Tunicates. Tunicates such as Appendicularia,are free swimming organisms. They are able to filter feed small food particles. The other types of tunicate organisms are benthic and are planktonic when in the larval stage.

chaetognatha
Arrow worms (their more formal name chaetognatha) are mostly holoplanktonic and are found nearly everywhere in the world. They are like nematoads, and they are transparent. Usually, their length is 3 inches long.

Krill are in the catagory 'Euphausids' and are found every where across the Earth. These are an important diet for whales. In cold water Krill eat diatoms, but in warmer wheather they feed on other animals.

Krill

The norweigen word for fish food is krill which is sorta ironic since they are whale food. They have been overfished for their omega-3 acids which are good for the human body. When the water is cold Krill eat diatoms and when the water is warm they feast on others. They can grow up to 3cm long.

Copepods
Macrozooplankton is a copepods.
It's ofthen found in fash water or marine.They swim with their antenna and their body shape they
eat zooplankton and any thing that
is smaller

Krill is a type of zooplankton that is eaten widely by whales. Krill comes from Norway where it means whale food. Krill can grow as big as 3cm long. In some countries across the world, krill is considered healthy food and many humans eat them too. Although, because of this, krill are overfished.

nanoplanktonic flagellates keeps bacteria under controlwhich keeps the population under control.long tail used for flagellates or by hair-like strucure called cilia. and some dinoflagellates are responsible for harming fish.

Chaz said...

Nanoplanktonic Flagellates are a type of zooplankton that kill and eat larger organisms, which keeps bacteria away from overpopulation. They have a net-like structure that is used for capturing the bacteria.
