Schwartziella Obesa (Paperback)

High Quality Content by WIKIPEDIA articles! Schwartziella obesa is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae. Snail is a common name for almost all members of the molluscan class Gastropoda that have coiled shells in the adult stage. When the word is used in a general sense, it includes sea snails, land snails and freshwater snails. Otherwise snail-like creatures that lack a shell (or have only a very small one) are called slugs.
