Where Do Daphnia Come from?

Daphnia can be found in almost any permanent body of water, even in rain-filled tire ruts or several meters from the ground, growing in tree moss in a rainforest. They are mainly freshwater and the highest concentrations of Daphnia populations are found in the vegetation in most lakes and ponds.

Where are daphnia commonly found?

Daphnia populations can be found in a range of water bodies, from huge lakes down to very small temporary pools, such as rock pools (Figures 2.18 and 2.19) and vernal pools (seasonally flooded depressions). Often they are the dominant zooplanktor and form, as such, an essential part of the food web in lakes and ponds.
