Common Name: Hidalgo Scrubsnail
Domain: Eukarya
Kingdom:Animalia
Phylum: Mollusca
Class: Gastropoda
Order: Stylommatophora
Family: Ploygyridae
Genus: Praticolella
Species: Praticolella trimatri
Eukarya: This domain consists of animals, fungi, protists, and plants and they
are very diverse organisms (Encyclopedia of Life, 2012).
Animalia: This kingdom consists of animals that are multicellular. Most of the
animals get their energy from different organisms (Encyclopedia
of Life, 2012).
Mollusca: This phylum has molluscs that are invertebrates and they have a
mantle. This is a coat of epidermal tissue that borders the body (Encyclopedia
of Life, 2012).
Gastropoda: Most organisms in this class have slow locomotor organs and heavy
shells. Almost all have one single shell that may be coiled or not (Hickman
et. al.,2012).
Stylommatophora: They are mostly terrestrial and some lack shells. The
gastropods that have lung or lung-like organs have two sets of invaginable
tentacles (Encyclopedia of Life, 2012).
Polygyridae: These snails have reproductive organs and alike shell form within
different genera (Pilsbry, 1948). Their jaws are
ridged and the muscles are one single band which allows the pharynx and eyes to
retract (Encyclopedia of Life, 2012).
Praticolella
Praticolella trimatris: This species can be related to similar species in the same genus. With this, we can conclude from the species Praticolella ampla that this species has a small shell and a conic spire of around 4.5 to 5.75 whorls. Also has retractor muscles that are bifurcate or trifurcate pinal (Perez, 2011).
