Planorbis planorbis is a species of air-breathing freshwater snail, an aquatic gastropod mollusk in the family Planorbidae, the ram’s horn snails. This species is widely distributed across the Palearctic region, and is found south of Oslo in Norway and across Europe to parts of North Africa; it is also found as far east as Lake Baikal, Russia. The habitat of this species is shallow standing and slowly running freshwaters on a mud substrate, also ponds and temporarily drying flood waters, up to 1 metre depth. Planorbis planorbis does not tolerate intensive water movements but is tolerant to eutrophic conditions.

This species, like all planorbids, has a sinistral shell. The width of the shell is 10 – 20 mm, height 2.5 – 4 mm. The keel on the periphery of the shell is near the edge closest to the spire side, which is carried downwards in life. A rather thick and strong shell. It is not glossy and it has a paler keel to

Planorbella duryi (Ramshorn Snail) is a species of air-breathing freshwater snail, a pulmonate gastropod mollusk in the family Planorbidae, the ram’s horn snails.

Planorbella duryi can be an interesting addition to a community tank. These snails can be a good match for species tanks as well, like shrimp or snail tanks. Planorbella duryi can do a good job keeping a tank clean by eating uneaten food, dead or decaying plant matter, debris, detritus, and soft algae buildup on hard surfaces. A ramshorn snail can be seen for hours on end canvasing the tank for edible matter. They have the ability to move and bend their rubber-like bodies around very thin plant leaves, dangle from stems and stretch as they move from one hard surface to another. With a young Planorbella duryi, the inside of their bodies can be seen as they eat and digest food, because their shells are thin and translucent.
