Physical Features
The dark grey body (Galton,
2011) of the species
Pseudosuccinea columella, also called the American Ribbed Fluke Snail (American
ribbed),
has two tentacles that are triangular and flat on its fleshy head (Galton,
2011). These
tentacles, in contrast to the genus Succinea, lack eyespots at their
tips (Lee, 2011). Pseudosuccinea columella’s shell, when viewed from the top, has
a clockwise coil with very fine spiral lines crossing the growth lines (Galton,
2011).
Their shell, which ranges from ten to fifteen millimeters in length (American
ribbed), is very
fragile and thin and, when empty, it is translucent and brown. Some reddish
brown shells, however, have been discovered in locations where there is red
soil or clay in the ground (Galton, 2011).
