Tarebia granifera, common name (in the aquarium industry) the quilted melania, is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Thiaridae. "The effects of water level fluctuations on a gastropod community in the rocky marginal zone of Plover Cove reservoir, Hong Kong". A detailed account of the anatomy of Tarebia granifera was given by R. Tucker Abbott in 1952[4] together with notes on its biology and bionomics. The data represented on this site vary in accuracy, scale, completeness, extent of coverage and origin. [1], Anecdotal reports and observations suggest that in KwaZulu-Natal the indigenous thiarid Melanoides tuberculata is becoming less common and pressure from the spread of Tarebia granifera, particularly at high densities, is a possible explanation. [1], In the South Africa, the snail has colonized different types of habitat, from rivers, lakes and irrigation canals to concrete lined reservoirs and ornamental ponds. 2010. [1] This suggests that differentiation of germinal cells in the ovary and their subsequent arrival in the brood pouch as blastulae is not a continuous process over a breeding season but occurs as one or more 'cohorts' or 'pulses' which stop before the birth rate of young snails reaches its maximum.

[1] Initial introductions were presumably via the aquarium trade. Number: 29540: Author: Abbott, R.T. 2009). [1], Studies on the ecological impact of Tarebia granifera are urgently needed. "Bionomics of, Gutierrez A., Perera G., Yong M. & Fernandez J. [1] There is no doubt that Tarebia granifera is able to pass unharmed through pumps, probably as juveniles. Description The quilted melania, Tarebia granifera, is a relatively small freshwater snail with an operculum ranging in size from 6-40mm, average of 25mm. These snails are peaceful and solitary; will not engage with tankmates.- [1] It favours turbulent water and tolerates current speeds up to 1.2m.s−1 and possibly greater. [1] Tarebia granifera also serves as intermediate host for the philopthalmid eyefluke Philopthalmus gralli Mathis & Ledger, 1910 which has recently (2005) been reported affecting ostriches Struthio camelus on farms in Zimbabwe. Malaysian trumpet snails (Tarebia granifera) Conclusion: cleaner fish for the aquarium. But since they do no harm I have not done anything about it. (2009) that the species often keeps most of body and shell buried in substrate in both field and in aquarium; this could lead to an underestimation of population proliferation, or an overlook of established populations altogether. This information is preliminary or provisional and is subject to revision. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables. Southwestern Naturalist 55(1):115-117. http://www.bioone.org/doi/abs/10.1894/JS-26.1. U.S. Habitat: The quilted melania is a freshwater snail that prefers: -Riffles of shallow fast-moving freshwater streams (Very rapid water flow is usually avoided) -Substrate consisting of sma… [1], In addition to its role as intermediate host for several economically important trematode species, Tarebia granifera has colonized water reservoirs, dams and ponds on the premises of three large industrial plants in northern KwaZulu-Natal and been pumped out of at least one of them, blocking water pipes and damaging equipment. Tarebia granifera (quilted melania) Mollusks-Gastropods Exotic. Involuntarily, I have in these tanks also flatworms (Rhabdocoela?). 25 Pink Ramshorn Snails Pond Aquarium Algae Freshwater 1/8 inch to 1/4 inch $20.00 20+ Malaysian Trumpet Snails Live Freshwater Aquarium Snail Substrate Cleaners [1] Appleton & Nadasan (2002)[20] estimated onset of maturity at 10–12 mm shell height but unpublished data[1] suggest a height closer to 8 mm in line with other published studies. 2009). Samadi S., Balzan C., Delay B. Besides the Nano-Cubes it is one of the smallest fishtanks available and at the same time also the best-selling tank size. The list of references for all nonindigenous occurrences of Tarebia granifera are found here. [2020]. In South Africa, T. graniferawas first recorded in an estuarine environment in the St Lucia Estuary. [1], Little is known of the long term population fluctuations of Tarebia granifera and findings seem to be contradictory. It is noted by Appleton et al. [6], Tarebia granifera is both parthenogenetic and ovoviviparous,[1] although males have been reported. [1] Intermediate forms exist. [1] These records show that Tarebia granifera is able to colonize brackish and moderately saline habitats and reach high densities there. [1], Dissection of Tarebia granifera showed blastula stage embryos in the brood pouches of snails as small as 8 mm shell height. [1] Prominent among these is the dense population (±6038 m2) found at a salinity of 9.98‰ (28.5% sea water) in Catalina Bay, Lake St Lucia, iSimangaliso Wetland Park, KwaZulu-Natal. The introduction and spread of Thiarids in the United States. (1987),[22] Ferrer López et al. MolluscaBase eds. (1992)[13] also suggested that Tarebia granifera density was positively correlated with Ca2+ concentrations and negatively with NH4 concentrations. "Studies on the morphology of cercariae obtained from freshwater snails at Erawan waterfall, Chaniotis B. N., Butler J. M., Ferguson F. F. & Jobin W. R. (1980). [1] In KwaZulu-Natal it has been collected in water flowing at up to 1.2 m.s−1 which is likely to exceed the current speeds of at least the lower and middle reaches of many rivers and streams in South Africa making these watercourses open to colonization. Ceratophyllum demersum, Potamogeton crispus, Nymphaea nouchali). A. [1] Both the intact and damaged specimens could have been alive when passed and perhaps survived had they been deposited in water. Tarebia granifera is resistant to turbidity and pollution and it tolerates a small degree of salinity (Benthem-Jutting 1956, Kartayev et al. Tarebia granifera, (Spike Tail Trumpet Snail, Quilted Melania), is a species of freshwater snail with an operculum, an aquatic gastropod mollusk in the family Thiaridae. [1] Even though the shell of Tarebia granifera is thick, most of these juveniles had been partially crushed with only a few still intact.

Jason is a biological scientist and project manager with nearly 20 years of professional experience and has held positions with Florida Fish and Wildlife Research Institute, U.S. This snail is native to south-eastern Asia, but it has become established as an invasive species in … Means of Introduction: This species is spread through the aquarium trade (Abbott 1952). [1] Most Tarebia granifera are therefore clones of the female parent. Selected chemical and physical characteristics of the water from tanks and trays were measured using a YSI model 556 MPS Water Logger . [1], Attainment of sexual maturity in Tarebia granifera is generally indicated by the size of the smallest snail observed to give birth rather than a histological assessment of the development of the gonad and associated reproductive structures. Ukrainian Journal of Ecology, 2018, 8(1), 975-982 doi: 10.15421/2017_301. "The occurrence, bionomics and potential impacts of the invasive freshwater snail. 100 mollusks of M. tuberculataand T. graniferamolluscs were inhabited to the aquarium. (1997). [1] Importantly, unshelled embryos (blastula, gastrula and trochophore stages) were not found in snails >16 mm and the numbers of shelled embryos themselves decreased in the largest snails, >24 mm. Vargas M., Gomez J. [1] Where densities are high, Tarebia granifera may also occur on marginal, trailing vegetation and the floating Common Water Hyacinth Eichhornia crassipes as well. Yong M., Sanchez R., Perera G., Ferrer R. & Amador O. This species occurs in several southern states of the U.S.: Butler J. M., Ferguson F. F., Palmer J. R. & Jobin W. R. (1980). Florida, Hawaii, Idaho, Texas, Puerto Rico and US Virgin Islands. It is the user's responsibility to use these data consistent with their intended purpose and within stated limitations. The introduction of this species in the Caribbean has affected the native hermit crab shell-use and behavior (van Oosterhout et al. [1][24] Live sperm were present in the testes of these males but the genitalia were apparently non-functional. This species is found from a range of environments; large rivers to small springs, in mountains and valleys, and silty or sand bottoms, riffles as well as pools (Abbott 1952; Prentice 1983). [6], Two color forms of Tarebia granifera exist, one has a pale brown body whorl and a dark spire (see photo on the right) and in the other the shell is entirely dark brown to almost black (see photo on the left). [1] The South African indigenous thiarids Thiara amarula, Melanoides tuberculata, and Cleopatra ferruginea are considered particularly vulnerable. [1] Despite the very high densities recorded in the Nseleni River, indigenous invertebrates were still present in the sediments including:[1] bivalve Chambardia wahlbergi, chironomids, oligochaetes (tubificids) and burrowing polychaetes were also found but in very low numbers. 2013). The freshwater gastropod Tarebia H. Adams & A. Adams, 1854, are found in rivers, lakes, and other limnetic habitats. (1981). [1] It has not been possible to calculate the rate of dispersal. [1] Reported variation in maturation period varies from 97–143 days (3.2–4.8 months)[10] under the laboratory conditions to 6–12 months, also from laboratory data. (1987). Both species were later reported from the spring-fed The Biologist 53(3):133-135. and A. J. Benson, 2020, US Fish and Wildlife Service Ecological Risk Screening Summary for. In the Caribbean, T. granifera is used as a biological molluscicide to replace native Biomphalaria snails that are vectors for schistosomasis in humans (Appleton et al 2009; van Oosterhout et al. Initial introduction of this parthenogenetic snail to the Neotropics from Asia is presumed to have been a consequence of the aquarium trade, though intentional introductions have occurred in an attempt to reduce schistosomaisis outbreaks [21]. [1], This spread will doubtless continue into northern South Africa, Moçambique, Zimbabwe and beyond. This freshwater prosobranch gastropod is native to Southeast Asia, and has invaded aquatic ecosystems in North America, South America and Africa (Appleton et al. [1] Males were found in most (6/7) populations examined in Puerto Rico but were generally uncommon at up to 22.7% of the population (mean 4.6%). (1987)[22] and Ferrer López et al. [1], Tucker Abbott (1952),[4] Chaniotis et al. (2010)[14] of Pinar del Río Province, Cuba have reported population densities of Tarebia granifera of 85 individuals/m2, well above those of its endemic relatives (5 individuals/m2). Appleton C.
