Shell description

The genus Libera was described by Andrew Garrett in 1881. Garrett's type description reads as follows:[3]

Shell small, widely umbilicated, umbilicus (in adults) strongly constricted so as to form a cavernous or pouch-like cavity; whorls 7-9, costulate or striate, last one angulata or carinate, rarely rounded; aperture subrhomboidal or securiform; peristome thin, simple, straight; parietal region with one or two, and the palate with (rarely without) two or three, internal laminae; columella emarginate and furnished with a spiral fold.

Life cycle

These snails lay their eggs into the umbilicus of their own shells.[4]

gollark: It does not, in fact, ever experience data loss, due to our uncountably infinite redundancy policy and utterly unchanging memory cell™ technology.
gollark: This cannot happen. Our storage is very good.
gollark: However, they effectively cannot die since we can just reinstantiate archived Olivias as needed.
gollark: They do not, we attain that from a separate subsystem.
gollark: We have a brainscan of them on file.
