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.

Like Daphnia, which is also a type of water flea, Spiny Water Fleas can either reproduce asexually, to achieve very dense populations, or sexually, to produce hardy resting eggs. Unfortunately, Daphnia are a favorite prey of the larger B. longimanus. The best known genus is Daphnia, ubiquitous in ponds and streams in Europe and North America. The water flea is microscopic in size, typically measuring only about 0.2 to 3.0 millimetres (0.01 to 0.12 inch) long.

Author information: (1)Graduate School of Environmental Science, Hokkaido University, Sapporo, Hokkaido 060-0810, Japan. 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).

Daphnia are commonly found in freshwater. 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.

The water flea is microscopic in size, typically measuring only about 0.2 to 3.0 millimetres (0.01 to 0.12 inch) long. It has a discrete head bearing antennae and a bivalve carapace that encloses all or most of the trunk and abdomen. The genus “Daphnia” is a group of aquatic organisms which are commonly known as “water fleas” and can range in body length from 0.2–8.0 mm with the exception of Leptodora, which measures up to 18 mm. Daphnia are commonly found in freshwater. They live in almost every nutrient-rich (eutrophic) body of water. Daphnia are filter feeders that direct small suspended particles into their mouth by a water current produced by their leaf-like legs (Figure 1).
