Daphnia are small, planktonic crustaceans, which are commonly called water fleas because of their swimming style. They live in various aquatic environments ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Daphnia pulex was the first crustacean to have its genome sequenced.

It takes its nickname from the way it propels itself through the water, which resembles the hop of a flea. Daphnia, the most common microscopic crustacean, can be visible to the naked eye, with lengths ranging from 0.2–5 mm.

The Daphnia magna, more commonly known as water flea, is indigenous to ponds and lakes in northern and western North America. This crustacean has an outer transparent covering called the carapace. The unique physiology of the water flea is useful in translational research allowing researchers to visibly study all of the bodily systems without causing harm to the specimen (2).

Its huge consumption in human activities resulted in the increasing awareness of its toxicity in the aquatic environment due to their active ingredients. Daphnia is a

Daphnia is a genus of small planktonic crustaceans, 0.2–5.0 mm (0.01–0.20 in) in length. Daphnia are members of the order Cladocera, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas.

Daphnia are extremely widespread and common throughout the world. Daphnia pulex is the most common species of the water flea, an organism which can be found in almost every permanent, eutrophic (nutrient-rich) water body. A few species are marine, but generally Daphnia, including Daphnia pulex, are freshwater organisms ( Miller, 2000 ). The water flea Daphnia grows its own helmets, spikes and crests in response to chemical cues that predators are near.

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.
