Sididae
Genus Guides
2Sididae is a of ctenopods (small planktonic crustaceans) in the order Diplostraca. The family comprises approximately 6 and at least 20 described , including well-known genera such as Diaphanosoma, Sida, and Latona. Members are primarily freshwater inhabitants distributed across multiple continents, with some species introduced to regions outside their native ranges.

Identification
Sididae can be distinguished from other ctenopod by morphological features visible under microscopy, including structure and post-abdominal claw . Specific identification requires examination of fine morphological details such as antennule structure, pore arrangement, and thoracic limb morphology; keys for regional faunas exist for some areas including Brazil.

Habitat
Freshwater environments including lakes, , and river systems. Some occupy limnetic (open water) zones, while others occur in vegetation-associated areas. Waters range from oligotrophic to eutrophic conditions.
Distribution
distribution with records from Europe (Norway, Finland, Denmark, Sweden), Asia (Russia, Siberia, China, Thailand, Vietnam, India, Bangladesh), Africa (West Africa), South America (Brazil, Colombia), and North America (Vermont, USA). Some have been introduced to areas outside their native ranges.
Human Relevance
Some have been accidentally introduced by humans to areas outside their native ranges. Members serve as subjects in zooplankton studies and aquatic monitoring.
Similar Taxa

Taxonomic note
The Limnosida (containing L. frontosa) has been characterized as the most primitive member of the order Ctenopoda based on morphological analysis showing a combination of advanced and evolutionary primitive features.
