Filopaludina martensi (
Frauenfeld, 1864)
[2]

Synonyms [1] | |
Filopaludina martensi is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Viviparidae.
The shape of the shell is ovate-conic. [3] The apex is acute and violet-black in colour. [3] The umbilicus of the shell is very narrow. [3] There are fine spiral lines on the shell. [3] The color of the shell is green or dark brown-blackish. [3] The shell has 6–7 convex whorls. [3] Whorls are with upper spiral lines, some are obsolescently sculptured. [3] The last whorl is swollen. [3]
The aperture is oblique, ovately rounded. [3] The aperture is cerulean-white in colour. [3] The upper part of the aperture is not acute. [3] The peristome is straight, thick, blunt, often outwardly blackish. [3]
The width of the shell is up to 31 millimetres (1.2 in). [3] The height of the shell is up to 55 millimetres (2.2 in). [3] The length of the aperture is up to 21 millimetres (0.83 in). [3]
The operculum has the color of horn with golden shining and it is widely ovate. There are concentric lines on the operculum. [3]
This species was firstly described by Eduard von Martens under the name Paludina cingulata in 1860 based on specimen collected by Henri Mouhot. [3] Georg Ritter von Frauenfeld created a new replacement name Vivipara martensi for this species in 1864, because the name Vivipara cingulata was already used for a fossil species by Philippe Matheron before. [2]
Three subspecies are recognized, [1] but this species and its subspecies require revision. [1]
This species is found in Cambodia, Indonesia, Laos, Malaysia, Thailand and Vietnam. [1] The type locality is " Siam" (a detailed type locality was not given). [3]
Filopaludina martensi lives in canals and ponds. [4] It feeds (as do all other Viviparidae) as a filter feeder. [4] There are in development 0–14 juveniles in a brood-pouch of a female. [5] Female gave birth to juveniles mainly at night. [5] Parasites of Filopaludina martensi martensi include:
Parasites of Filopaludina martensi include trematode Multicotyle purvisi. [8]
Filopaludina martensi is used as part of the cuisine of Thailand. [4]
