However, it is relatively low when compared to the global database of the diversity and geographic distribution of planktonic marine copepods, in which 546 species of copepods have been registered for the oceanic zone of the Pacific, an extensive area named as the Central Tropical Pacific (Zone 19), which includes the ...
Where did copepods come from?
As a group, copepods originated from marine forms, but they have colonized all aquatic habitats, including hypersaline, brackish, and freshwater ecosystems, but also terrestrial and semi-terrestrial habitats.
Why do copepods live near the surface of the sea?
Many planktonic copepods feed near the surface at night, then sink (by changing oils into more dense fats) into deeper water during the day to avoid visual predators. ... They live as endo- or ectoparasites on fish or invertebrates in fresh water and in marine environments.
How do copepods eat?
Tiny crustacean zooplankton called “copepods” are like cows of the sea, eating the phytoplankton and converting the sun's energy into food for higher trophic levels in the food web. ...

Does live rock have copepods?
Copepods typically find their way into your tank as hitchikers via live rock, frags, and macro-algae. You can also introduce these beneficial copepods into your aquarium to help increase the diversity of species and boost populations.
Can Daphnia live in aquarium?
Daphnia are freshwater creatures that can be kept in a tank as small as 5 or 6 gallons and all the way up to 360 gallons! The main thing to look for in a tank is a greater surface area than depth. That helps mimic their natural environment of ponds and other freshwater habitats.
