Succinea sp. from Ghana ?

[brunni]

;D Washing out some shells by the stand pipe in the garden today, I found this little guy. He's only 13.8mm long ( just over ½ “). I found the empty shell in leaf litter and it is very fragile so I did not try and clean it.



The shell reminds me either of a Lymnaea sp. or a Succinea sp. On closer examination I settled for the latter as the first is a pond (aquatic) snail. Was I right ? If so, what species could it be ?

Numerous species are described from a multitude of areas and quite frankly they all look the same to me. Any help here ?

The shell looks a lot like a Succinea to me, but I am not an expert.

Today I found 2 more of these snails, this time smaller ( around 10 mm ) but alive. They were attached to a vertical wall that has been white-washed. This is absoute proof they're a land and not an aquatic snail. So indeed a Succinea sp.



They're probably absorbing the calcium that's in the white-wash ?

I would assume they are indeed absorbing the calcium from the white-wash.

It is definitely a Succinea, but Succinea are almost impossible to identify down to the species most of the time. DNA tests are usually required.
