Bulimulus tenuissimus is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the subfamily Bulimulinae. Distribution The native distribution of Bulimulus tenuissimus includes: Brazil – widespread in Brazil The non-indigenous distribution includes: North Carolina, USA Description The shell is perforate, ovate-conic, very thin, pellucid, scarcely shining, obsoletely and closely decussated by growth striae and delicate spiral lines. The shell is pale corneous in color, sometimes fulvous. The spire is conoid. The apex is rather acute. The suture is simple. The shell has six whorls that are slightly convex, increasing with moderate rapidity. The last whorl is convex, not descending in front, somewhat attenuated at base. The columella is suboblique, sometimes nearly vertical. The aperture is oval, colored like the exterior, onehalf the shell's length. The peristome is simple, unexpanded, acute. The right margin is regularly arcuate. The columellar margin is reflexed above, nearly covering the perforation. The width of the shell is 9 mm. The height of the shell is 17 mm. Ecology The reproductive biology of this species was studied by Silva et al. (2008): These hermaphroditic snails are mating and cross-fertilization normally occurs. When snails are isolated then self-fertilization can occur, but with the lower reproductive success. Eggs are laid in clutches from one to 252 eggs (in captivity). Snails are hatched after about 20 days. Bulimulus tenuissimus has long lifespan. Bulimulus tenuissimus can be fed for example with calcium and commercial bird food, lettuce or rations of various food components. Bulimulus tenuissimus is a host for a trematode of the genus Postharmostomum (family Brachylaimidae). Strongyluris-like larvae are a parasite of Bulimulus tenuissimus. Malacophagula neotropica (family Sarcophagidae) is a parasite of Bulimulus tenuissimus. A firefly is a predator of Bulimulus tenuissimus.
