Cyprididae

Part of speech: noun

Definitions

1. A family of small crustaceans belonging to the class Ostracoda, known for their bivalve-like shell structure
2. These microorganisms are often found in freshwater and marine environments, playing significant roles in the aquatic ecosystem
3. Characterized by their distinctive carapace and specialized appendages, they are important indicators of environmental conditions in their habitats

Etymology: Cyprididae takes its name from Cypris, the genus that gives the family its stem, and that genus name is itself a Latinised form of the Greek word for Aphrodite. The Greeks called the goddess Kypris after Cyprus, the island associated with her cult, so the shell-bearing crustaceans carry a goddess's epithet in their name. The "-idae" ending is the standard zoological marker for a family, formed from the genus name in the same way that many animal families are named. These are tiny crustaceans, mostly well under a millimetre to a few millimetres long, that live in fresh water, brackish water and the sea. Their two valves, the calcified shell halves hinged along the back, enclose the whole body, which is why people compare them to bivalve molluscs such as clams. Unlike clams, however, they are arthropods, related to other crustaceans, and the resemblance is an example of convergent evolution rather than kinship.

Synonyms: ostracods, seed shrimp, microcrustaceans, freshwater ostracods, marine ostracods
