Spawning individual of Pomacea canaliculata, photographed by Cláudio Dias Timm.

Belongs within: Caenogastropoda.

Bouchet et al. (2005) listed two families within Ampullarioidea, the Ampullariidae and Naricopsinidae. The Ampullariidae, apple snails, are a pantropical family of freshwater gastropods. Naricopsina is a genus of Jurassic marine gastropods, established as a separate family by Gründel (2001), who suggested that it might be ancestral to the Naticidae. Bouchet et al. (2005) did not cite their reasons for aligning Naricopsina with Ampullariidae.

Characters of Ampullariidae (from Simone 2004): Left siphon very long; pair of snout tentacles present. Osphradium elliptical, leaflets present; gill narrow and curved; lung sac present. Pericardium connected to pallial floor, ampulla in anterior aorta. Renal tissue a solid glandular mass confined in a separated chamber; intestinal loops in kidney chamber connected by a mesentery, anterior septate chamber present; nephrostome connected by an anterior chamber; urinary gutter a fold along rectum and pallial oviducts. Jaws very large; odontophore with multiple Ma muscles, H-fashion M3 muscle, M2 as adductor of jaw plates, M9 muscle present, pair of accessory cartilages present. Radular sac short, about same length as buccal mass; rachidial tooth broad, multicuspid, with basal pair of broad cusps. Salivary glands a single fused mass; oesophageal pouches with a dorsal fold; stomach walls at least dorsally muscular; several ducts to digestive gland; intestine with one to several small blind sacs near pericardium. Penis sac present, penis broad and short, penis shield present; albumen glands a compact mass; capsule gland with a complex, sometimes spiral inner duct; female pore a papilla; vaginal tube originating in anterior end of pallial oviduct. Eggs brooded in a jelly mass laid out of water.
