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 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.

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]
Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology, and also in the study of cells.
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.

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.
