Sphaerium is a genus of very small freshwater clams, aquatic bivalve mollusks in the family Sphaeriidae, known as the fingernail clams. The small clams in this genus are unusual in that many of them, such as Sphaerium corneum, can climb around underwater on aquatic plants, using their long and strong foot.

Species

  • Sphaerium nitidum Clessin, 1876 - Arctic fingernail clam
