Daphnia pulex is the first crustacean to have its genome sequenced. Availability of the genome sequence will have implications for research in aquatic ecology and evolution in particular, as addressed by a series of papers published recently in BMC Evolutionary Biology and BMC Genomics.
We recently reported a genetic increase in heat tolerance in urban compared to rural populations of the water flea Daphnia magna (Brans, Jansen, et al., 2017). Such an increase in heat tolerance was also reported in a study on urban thermal adaptation in terrestrial acorn …

These tiny critters are part of the freshwater plankton. A daphnia swims in a jerky motion, using branched antennae while eating algae, microscopic animals and organic debris. Watch its legs swirl food to its mouth. Its tiny size and transparent body helps it hide from hungry insects and fish. The water flea (Daphnia magna) was used as a sensitive indicator for assessing the toxicity due to synthetic detergents. Acute and chronic toxicity of detergents to the water flea was studied under laboratory conditions by following the median tolerance limit (TLM) at 48 hr and the rate of survival. … 2010-12-31 2017-08-16 The sub-lethal and reproductive effects of acute and chronic exposure to flowback and produced water from hydraulic fracturing on the water flea Daphnia magna Article Jan 2017 It’s baby making time!

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 members of the order Cladocera, and are one of t 2021-04-10 · 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. It has a discrete head bearing antennae and a bivalve carapace that encloses all or most of the trunk and abdomen. Daphnia are extremely widespread and common throughout the world.

Water flea experiment from Microscopes for Schools. Observing daphnia pulex ( water flea) under a compound microscope.
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. 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 ).
