context_page_description: Nassodonta dorri is a species of brackish water snail, with gills and an operculum, a gastropod mollusk in the family Nassariidae, the nassa mud snails or dog whelks.
context_section_description: The shell is thick. The shape of the shell is oblong-ovate. The shell has 2.25 distinctly shouldered whorls. The spire is low and obtuse. The body whorl is subcyrindrical. The width of the shell is 8.0-9.6 mm. Shell length is 12.0-14.9 mm.
  Operculum is thin, elongate, oval with basal nucleus. The length of the operculum is 5.7 mm.
  Head is small and broad, with very short, thick cephalic tentacles. Eyes are slightly elevated on prominent ocular peduncles at tentacle outer bases. Foot is broad, fleshy, overlapping sides of operculum in preserved specimens. Frontal part of the foot (propodium) is narrow with posterior extent marked by indistinct notch, poorly demarcated from mesopodium. There is shallow propodial pedal gland along anterior edge, with two histologically distinct subepithelial gland cells. Metapodium has no posterior tentacles.
  Mantle cavity is short, less than one-half whorl in length. There is reno-pericardial complex just behind the mantle cavity. Mantle cavity is slightly asymmetrical, slightly deeper at left side in front of pericardium.
  Reproductive system: has separate sexes (i.e. these snails are dioecious).
  Females: ovipositor is forming deep, simple pore surrounded by weakly developed subepithelial glands.
