Hi squeak. Sorry you got edited. I’ll ask a mod if you had any super vital info that didn’t make it.
From http://www.tafi.org.au/zooplankton/imagekey/copepoda/index.html
“Copepods are probably the most common and abundant holoplanktonic organisms worldwide, occurring in all oceans, seas, estuaries, rivers and lakes.”
From http://en.wikipedia.org/wiki/Copepod (first sentence)
“Copepods are a group of small crustaceans found in the sea and nearly every freshwater habitat.”
