Cladocera are commonly referred to as water fleas due to the hopping motion they make when moving about in the water. Daphnia are distributed throughout much of the world, though they are less abundant in the tropics where water bodies are usually nutrient poor (only six of the 50 daphnia species occur in the tropics). 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.
It takes its nickname from the way it propels itself through the water, which resembles the hop of a flea.

About 35 percent of the genes are brand new to science. Next we removed the excess solution from the Daphnia and flushed it with aquarium water. Using the same procedure we monitored the effects of 1 1/2% and 2. 0% caffeine solutions and recorded our results and placed the Daphnia in the recovery tank. Request PDF | On Jan 1, 2009, M.M.E.-D.
Daphnia are filter feeders that direct small suspended particles into their mouth by a water current produced by their leaf-like legs (Figure 1). Daphnia 's common name of 'water flea' comes from its jump-like movement, which results from the beat of the large antennae used for swimming (Figure 1). Life cycle: All summer long, special Water Flea cysts called ephippia (pronounced i-FIP-ee-uh) lie on the bottom of the vernal pool. These ephippia are adapted to survive many long, hot summers. When rainwater fills a vernal pool, the ephippia hatch into female Water Fleas. There are no males!
