A family of small freshwater crustaceans including the clam shrimp, characterized by a bivalved carapace.
From 'Estheria' (genus name) + '-idae' (taxonomic suffix denoting a family). The suffix follows Linnaean taxonomic conventions for classifying organisms.
Estheriidae might be tiny and overlooked, but paleontologists love them because they're incredibly common in ancient rocks, making them perfect for dating and correlating geological layers!
