Ilavia

Ilavia is a genus of ostracods belonging to the family Cyprididae. Ostracods, also known as seed shrimp, are a class of Crustacea found in a wide variety of aquatic environments, from fresh water to marine habitats.

Ilavia species are characterized by their bivalved carapace, which encloses the body. This carapace is typically calcified and hinged along the dorsal margin. Identification of Ilavia species often relies on detailed examination of the carapace morphology, including ornamentation, shape, and size. Features of the soft body parts, such as the limbs and antennae, may also be used for species differentiation.

Ilavia ostracods are generally small, often measuring less than a millimeter in length. They are typically benthic organisms, meaning they live on or near the bottom of aquatic habitats. Their diet may consist of detritus, algae, bacteria, or other small organic particles.

The geographic distribution of Ilavia varies depending on the specific species. They have been found in various parts of the world, often in freshwater environments like lakes, ponds, and rivers. Understanding their distribution and ecology can be valuable for paleoecological studies, as ostracods are often well-preserved in sedimentary records, providing information about past environmental conditions.
