Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda , and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas .
Daphnia magna is a key species in many lentic habitats. It can be found in lakes and shallow ponds rich in organic matter sediment. [6] Numerous natural predators are known and can lead to plastic phenotypic responses. In the presence of kairomones, Daphnia spp. develop conspicuous protective structures as an elongated spine and a large body ...

Daphnia pulex. The genus Daphnia (Crustacea: Cladocera: Daphniidae) contains over 200 species of water fleas, many of which are in need of further taxonomic investigation (species inquirendae; marked with asterisks). [1]
A light micrograph or photomicrograph is a micrograph prepared using an optical microscope, a process referred to as photomicroscopy.At a basic level, photomicroscopy may be performed simply by connecting a camera to a microscope, thereby enabling the user to take photographs at reasonably high magnification.
Daphnia studeri is a species of microcrustacean in the genus Daphnia. D. studeri lives in oligotrophic freshwater and slightly brackish lakes in Antarctica and sub-Antarctic islands. Adult Daphnia studeri are typically 1.5 to 2.5 mm (0.059 to 0.098 in) [ 1 ] and colorless or slightly pink.

IF can additionally be used in combination with other, non-antibody methods of fluorescent staining, e.g., the use of DAPI to label DNA. [10] [11] Examination of immunofluorescence specimens can be conducted utilizing various microscope configurations, including the epifluorescence microscope, confocal microscope, and widefield microscope.
