The Aciculidae are a family

s which have opercula
. (An operculum is a little door that closes the shell when the animal retracts into it.) In other words, Aciculidae are terrestrial
operculate gastropods.
Even though Aciculidae are land snails, they live in rather wet conditions, among mosses and dead leaves and they have sometimes been described as "winkles come ashore".

Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...
