Indoplanorbis exustus

Indoplanorbis exustus is the only extant species in the genus Indoplanorbis. == Description ==

of Indoplanorbis exustus: v.d. = vas deferens, p.s. = penis heath, sp. = sperm duct, p. = penis, e.p. = external opening. The shell of this species, like all planorbids is sinistral in coiling, but is carried upside down and thus appears to be dextral. The shell of Indoplanorbis exustus is discoid with rapidly increasing whorls. Each whorl is higher than it is wide. The width of the shell is 5–25 mm. The height of the shell is 4.5–13 mm. ==Distribution==

The freshwater snail Indoplanorbis exustus is found across Iran, Nepal, Southeast Asia (for example Thailand), Arabia and Africa. to recent introductions by human activities (Brandt's view has been frequently cited in the literature on Indoplanorbis). In contrast to Asia, the well documented appearance of the snail in Africa (e.g., Nigeria and Ivory Coast) and more recently (2002) in the Lesser Antilles, Planorbella duryi and Biomphalaria pfeifferi have similar shells. and its hemocytes. == Ecology ==

In captivity Indoplanorbis exustus can be reared on lettuce and spinach. Habitat The snail is found in small ponds, pools, and less commonly in rice paddy fields. Consequently, dispersal may occur in clumps of mud adhered to the bodies of cattle or across water in vegetation mats. It is possible it could be transported by birds. Raut & Aditya (2002) hypothetized that Pomacea bridgesii could be a potential biocontrol agent for Indoplanorbis exustus. • Hypoderaeum conoideum – as the first intermediate host Ethanol extract of Solanum xanthocarpum has molluscicidal activity against Indoplanorbis exustus LC50 = 198.00 mg/L and LC90 = 236.80 mg/L. The latex of Euphorbia milii has molluscicidal activity against Indoplanorbis exustus that depends on its hybrid of the plant. The molluscicidal activity of latex of Cascabela thevetia, Alstonia scholaris and Euphorbia pulcherrima against Indoplanorbis exustus was examined by Singh & Sunil (2005). ==Human use==

It is a part of ornamental pet trade for freshwater aquaria. ==References==
