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:
The non-indigenous distribution includes:
- North Carolina, USA[3][4]
Description
The shell is perforate, ovate-conic, very thin, pellucid, scarcely shining, obsoletely and closely decussated by growth striae and delicate spiral lines.[5] The shell is pale corneous in color, sometimes fulvous.[5] The spire is conoid.[5] The apex is rather acute.[5] The suture is simple.[5] The shell has six whorls that are slightly convex, increasing with moderate rapidity.[5] The last whorl is convex, not descending in front, somewhat attenuated at base.[5] The columella is suboblique, sometimes nearly vertical.[5]
The aperture is oval, colored like the exterior, onehalf the shell's length.[5] The peristome is simple, unexpanded, acute.[5] The right margin is regularly arcuate.[5] The columellar margin is reflexed above, nearly covering the perforation.[5]
The width of the shell is 9 mm. The height of the shell is 17 mm.[5]
Ecology
The reproductive biology of this species was studied by Silva et al. (2008):[2] These hermaphroditic snails are mating and cross-fertilization normally occurs.[2] When snails are isolated then self-fertilization can occur, but with the lower reproductive success.[2] Eggs are laid in clutches from one to 252 eggs (in captivity).[2] Snails are hatched after about 20 days.[2]
Bulimulus tenuissimus has long lifespan.[2]
Bulimulus tenuissimus can be fed for example with calcium and commercial bird food,[2] lettuce or rations of various food components.[6]
Bulimulus tenuissimus is a host for a trematode of the genus Postharmostomum (family Brachylaimidae).[2][7]
Strongyluris-like larvae are a parasite of Bulimulus tenuissimus.[8]
Malacophagula neotropica (family Sarcophagidae) is a parasite of Bulimulus tenuissimus.[9][10]
A firefly is a predator of Bulimulus tenuissimus.[11]
