let me guess, since no one answered. A million. I wouldn't call them animals though;)
There are many microscopic animals. You will need a microscope and a slide mounting kit to see them. You might have a still or slow moving natural body of water near you. If so get a jar of water from it. Put a drop between two slides and look at it under your microscope. You may see some type of animal life.
Whales usually eat Plankton, which is a microscopic algae type thing. Many things eat microscopic animals, I believe herring is one species.
A tiny amount of liquid water, of microscopic size -- though still containing a huge number of water molecules. Many droplets must merge to form just one normal-size drop of water.
Fish in the water, vegitation in the water and on the shore, animals that live in the area around the river, bacteria in the water, many microscopic organisms in the river ect.
A Jellyfish undulates its bell in order to move through the water.-----octopi, squid, some species of flatfish..many species of plankteon and microscopic animals move via undulation, snakes use a form of undulation to move in the water, some fish use undulating fins to move ..
it doesn't all animals need water to survive over wise they would be extinct in much respect every life source of which need some sort of energy or water to survive. what you mean is that pollution which can effect water and contaminate it could effect a animals life if so the animals drinks the water then it will make the animal ill as there are many microscopic parasites and germs which can contaminate water, for some water is unlikely to be effected as they are filtered and cleaned however in poorer countries they have to drink dirty water and also this means animals will to.
Animals that live in water called Aquatic animals. There are equal number of animals in water that are on earth. The name of animals that live in water areHagfishElectric EelPlatypusCuttlefishMantis ShrimpSalmonand many more....
yeah man water is clear You can see large (macroscopic) living things in water, and many microscopic living things as well.
Approx. 0,33.1018 hydrogen atoms for a drop of 1o microliters.
No, plankton are defined as free-floating, such as many microscopic species and then larger animals such as jellyfish. Sharks are cartilaginous fish that can control their movement.
Coccidia is classified as subclass of microscopic spore. It is a intracellular parasite that can infect both animals and humans, and can cause many disease.
butterflies...... maby not...?
