Ancylid gastropods are small, fragile limpets found in most freshwater habitats.
All freshwater limpets in the southeast belong to this family. Other families occur elsewhere in North America and in other places. Little is known about these animals, and diverse opinions exist among malacologists as to how many species are recognizable. However, this appears to be an overreduction, and several southern species were synonymized that appear worthy of recognition. Six species are known to occur in Florida.
