A group of small crustaceans with bivalve shells resembling tiny clams, found in freshwater habitats.
From Greek konche (shell) and ostrakon (shell or oyster). Named by zoologists who recognized these crustaceans' shell-like appearance.
Conchostraca are like the living fossils of the crustacean world—they've barely changed in 300 million years, making them perfect for studying ancient ecosystems!
