Bulinus nasutus is a species of tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
The distribution of Bulinus nasutus includes three countries in East Africa:
Type locality is Bagamoyo, [4] now in Tanzania.
The width of the shell is 12 mm. [4] The height of the shell is 25 mm. [4]
The diploid chromosome number is 2n = 36. [4]
Bulinus nasutus lives in temporary pools, ditches and burrow-pits. [4]
High concentration of chloride (468-2220 ppm Cl) have been found in pools inhabited by Bulinus nasutus in Tanzania. [4]
Bulinus nasutus can aestivate in the dry mud for about 5–8 months. [4] Respiration of Bulinus nasutus during aestivation is probably aerobic. [4] They aestivate on margins of pools, and thus stop aestivation only in optimal conditions, when the pool has much water. [4]
Webbe (1962, 1965) [5] [6] described population dynamics of Bulinus nasutus in Tanzania. [4]
Mature snails lay eggs during the whole life span, primarily immediately after the main rainfall. [4] Snails 8 weeks old, whose shell is about 8 mm in height, are mature and can lay eggs. [4] However they require more than 12 months of life and 1-2 aestivation periods in order to reach their full size. [4]
This species is an intermediate host for:
Schistosoma is a genus of trematodes, commonly known as blood flukes. They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization as the second-most socioeconomically devastating parasitic disease, with hundreds of millions infected worldwide.
Schistosoma haematobium is a species of digenetic trematode, belonging to a group (genus) of blood flukes (Schistosoma). It is found in Africa and the Middle East. It is the major agent of schistosomiasis, the most prevalent parasitic infection in humans. It is the only blood fluke that infects the urinary tract, causing urinary schistosomiasis, and is the leading cause of bladder cancer. The diseases are caused by the eggs.
Bulinus is a genus of small tropical freshwater snails, aquatic gastropod mollusks in the family Bulinidae, the ramshorn snails and their allies.
Bulinus nyassanus is a species of small air-breathing freshwater snail with a sinistral shell, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies. This species is endemic to Lake Malawi in Africa, where found both in shallow and relatively deep water. Its shell generally reached a size of up to around 14 mm × 11 mm.
Bulinus truncatus is a species of air-breathing freshwater snail with a sinistral shell, an aquatic pulmonate gastropod mollusk in the subfamily Bulininae of the family Bulinidae, the ram's horn snails and the like.
Biomphalaria glabrata is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.
Biomphalaria stanleyi is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.
Biomphalaria sudanica is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod belonging to the family Planorbidae, the ram's horn snails. Biomphalaria sudanica has a discoidal, brown shell with an approximate shell diameter of 9–11mm. Biomphalaria sudanica is a medically important pest, due to it being an intermediate host of the intravascular trematode genus, Schistosoma.
Indoplanorbis is a genus of air-breathing freshwater snail. Its only member species is Indoplanorbis exustus, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails. The species is widely distributed across the tropics. It serves as an important intermediate host for several trematode parasites. The invasive nature and ecological tolerance of Indoplanorbis exustus add to its importance in veterinary and medical science.
Schistosoma spindale is a species of digenetic trematode in the family Schistosomatidae. It causes intestinal schistosomiasis in the ruminants.
Bulinus forskalii is a species of tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Bulinidae, the ramshorn snails and their allies.
Bulinus africanus is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Bulinus tropicus is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Bulinidae, the ramshorn snails and their allies.
Bulinus natalensis is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies. Its geographical distribution is largely limited to Kwazulu-Natal in South Africa. This species occurs in standing, perennial freshwater habitat and has the ability to aestivate for up to six months during a drought.
Bulinus globosus is a species of a tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Bulinus abyssinicus is a species of tropical freshwater snail with a sinistral shell, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies.
Bulinus jousseaumei is a species of tropical freshwater snail, an aquatic gastropod mollusk in the family Planorbidae, the ramshorn snails and their allies. Like other planorbids, the shell of the species is sinistral in coiling.
Planorbarius metidjensis is a freshwater lung snail.
