Pomacea (pomacea) haustrum
The shell is also heavily banded with dark-brown bands.
Near the shell opening (aperture) the shell
becomes lighter in colour.
The suture is deeply indended, much like in Pomacea canaliculata and Pomacea maculata. Compared
with Pomacea canaliculata, haustrum has a less round and relatively higher shell.
Operculum: The operculum is moderately
thick and corneous. The structure is concentric with the nucleus near the centre of the shell. The operculum can be retracted
in the aperture (shell opening).
These snails lay green eggs above the water line.
