Biology:Afropomus
Afropomus balanoideus is a species of freshwater snail, an aquatic gastropod mollusc in the family Ampullariidae (apple snails). It is the only species in the genus Afropomus.[1][2] Afropomus is the type genus of the subfamily Afropominae.[3]
Based on the anatomy, mainly that of the reproductive system, Afropomus appears to be a primitive genus within the Ampullariidae.[1] This basal position of Afropomus within Ampullariidae has also been confirmed by molecular phylogeny.[4]
Subspecies
Subspecies of Afropomus balanoideus include:
- Afropomus balanoideus balanoideus (Gould, 1850)
- Afropomus balanoideus nimbae Binder, 1963[1] This subspecies from the Ivory Coast and Senegal has a higher spire.
Distribution
The distribution of Afropomus balanoideus includes:
The type locality is Cape Mount in Liberia.[1]
Its presence in Ghana is uncertain.[5]
Description
The shape of the shell is ovate.[1]
The width of the shell is 20 mm.[1][6] The height of the shell is 22–23 mm.[1][6]
Ecology
Afropomus balanoideus lives in clean water in ditches, creeks and small rivers.[5][1] It requires a high concentration of oxygen.[5]
