Filopaludina martensi is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Viviparidae.

Description

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]

Taxonomy

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 Pierre Philippe Émile Matheron before.[2]

Subspecies

Three subspecies are recognized,[1] but this species and its subspecies require revision.[1]

Distribution

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]

Ecology

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:

Human use

Filopaludina martensi is used as part of the cuisine of Thailand.[4]
