Copepod adults and copepodites.
On the contrary, it is a very small copepod crustacean.
Cholera bacteria occur naturally in coastal waters,
where they attach to tiny crustaceans called Copepods.
Thus, these Copepods have an intestine, which is stimulated by the movement of the hemolymph.
All the Copepods combined form the largest biomass on the Earth,
followed close behind by the Antarctic krill.
Just so you know, filtering out Copepods is as easy as running water through a cloth filter.
Almost all varieties of copepod do not posses or need hearts or circulatory systems,
due to their tiny size.
With these above things combined, Copepods are one of the most important organisms on the planet,
right up there with Earthworms.
The Copepods can be added in significant numbers
to the water where mosquitoes breed and will eat the mosquito larvae found there.
The guinea worm also
develops within the copepod's digestive system and, if you drink water with Copepods in it, will then find its way into you.
In order to achieve these great jumps,
used to evade predators, the copepod uses two propulsion mechanisms and a very fast nervous system,
which is very rare for invertebrates;
Copepods often found in unfiltered drinking water has raised a major problem with orthodox Jews as
Copepods, being crustaceans, are not kosher and are too large to be ignored.
Relative to their size, typically about 1mm long, Copepods are also the world's fastest animal, being able to
jump at a rate of about a half a meter per second.
In some countries, such as Peru and Bangladesh, there has been a strong correlation found between Copepods in drinking water and cholera,
as the cholera bacteria attach to the surface of planktonic animals.
