Ecology > Habitat

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. It reaches very high densities, up to 21 000 m², and is likely to impact on the entire indigenous 底棲生物 of the natural waterbodies of the region – more so than any other invasive freshwater invertebrate known from the South Africa. The South African indigenous thiarids Thiara amarula, 瘤拟黑螺, and Cleopatra ferruginea（英语：） are considered particularly vulnerable.
Most localities in South Africa (93%) lie below an altitude of 300 m above sea level where an estimated area of 39 500 km2 has been colonized. The only known localities outside this area are the Umsinduzi River in 彼得马里茨堡 and its confluence with the Umgeni River（英语：） which lie closer to 500 m. R. Tucker Abbott（英语：） (1952) noted that on 關島 Island, Tarebia granifera occurred in streams and rivers at 983 m altitude but that these watercourses were consistently above 24 °C indicating that temperature may be an important determinant of distribution.
Tarebia granifera also occurs in several estuaries along the KwaZulu-Natal coast. Prominent among these is the dense population (±6038 m2) found at a 鹽度 of 9.98‰ (28.5% sea water) in Catalina Bay, Lake St Lucia, 伊西曼格利索湿地公园, KwaZulu-Natal. These records show that Tarebia granifera is able to colonize 汽水 (水域) and moderately saline habitats and reach high densities there. From observations in 波多黎各 it was suggested that snails could survive temporarily saline conditions for several weeks by burying themselves in the substratum（英语：）, emerging when fresh water returned.
In common with other Thiaridae, Tarebia granifera is primarily a 海底生物界 species and in South Africa has been collected on a variety of substrata in both natural and artificial waterbodies, e.g. sand, mud, rock, concrete bridge foundations and the concrete walls and bottoms of reservoirs, irrigation canals and ornamental ponds. Many of these habitats were vegetated and the associated vegetation included many types of 水生植物 單子葉植物 (e.g. 紙莎草, 藨草属 sp., 香蒲属 sp., 芦苇属 sp.) and 双子叶植物 (e.g. 金鱼藻, 菹草, 延药睡莲). Where densities are high, Tarebia granifera may also occur on marginal, trailing vegetation and the floating Common Water Hyacinth 凤眼蓝 as well. It favours turbulent water and tolerates current speeds up to 1.2m.s−1 and possibly greater. This habitat range is similar to that recorded for Tarebia granifera in Puerto Rico.
The major interest in Tarebia granifera outside Asia today is its invasive ability and its impact on indigenous 底棲生物 in colonized waterbodies. The pollution tolerance value is 3 (on scale 0–10; 0 is the best water quality, 10 is the worst water quality).
Typically half or more of these snails were buried in the 沉積物s and were not visible from the surface. This was also noticed in 水族箱 where they actively buried themselves in sand. Exact proportion of population of Tarebia granifera that is buried at any time is not known. There is also not known how long can snails remain buried.
Tarebia granifera will die at the temperature 7 °C in aquaria, but they do not live in water temperature under 10 °C in the wild.
