Overview Afropomus Asolene Felipponea Lanistes Marisa Pila Pomacea Saulea |
The new world genus Felipponea (Dall, 1919) contains 3 known species
(however it could turn out to be only 2). The type species is Felipponea
neritiformis (Dall, 1919).
These snails live in turbulent waters like small streaming rivers. This is reflected
in their neritoid shape (less resitance) and strong, thick shell. Snails with
large and fragile shells won't survive the conditions in this environment.

Note: Fabio Faraco is doing research on the Felipponea genus and he
expressed his doubts about the existence of 3 different species in this genus.
The different species described might be caused by the obvious difference between
the male and the female snail (take a look at Felipponea neritiformis).
In such case, only 2 Felipponea species exist as far as know. Keep in
mind that the last word in this hasn't been said.
