Classification:
Common name: Tiny liptooth
Scientific name: Lobosculum pustuloides
Domain: Eukarya
Kingdom: Animalia
Phylum: Mollusca
Class: Gastropoda
Order: Stylommatophora
Family: Polygyridae
Genus: Lobosculum
Species: Lobosculum pustuloides
Domain Eukarya:
Lobosculum pustuloides
is classified into the domain Eukarya because the cells are
eukaryotic. Each
cell in Lobosculum
pustuloides contains organelles located within a membrane (Hickman
et al, 2009).
Kingdom Animalia: The Kingdom Animalia is a diverse group that is characterized by cells that do not have a cell wall and instead have only a cell membrane. Lobosculum pustuloides also is a multicellular, heterotrophic organism (Hickman et al, 2009).
Phylum Mollusca: Animals in the phylum Mollusca all have coeloms allowing the organisms to have a hyrdrostatic skeleton and allows them to have a place of attachment for any internal organs and mesenteries. A soft body is another characteristic of mollusks, most of which are then protected by a hard calcium-containing shell. The body plan of mollusks is split into three different regions: the head-foot, the visceral mass, and the mantle. The head-foot is the location of motor and sensory organs. The visceral mass is the region of any internal organs and the mantle is a tissue layer that encloses the visceral mass and secretes a shell (Hickman et al, 2009).
Class Gastropoda: Class Gastropoda
includes snails, slugs, alabone, whelks, and periwinkles.
Gastropods are classified by undergoing torsion, a
process that results in the twisting of visceral mass so that
the anus is near the head.
Undergoing torsion allows the animal to have only one
small region that is not protected by a shell.
Some organisms experience detorsion and therefore have
the mouth and anus at opposite ends of the body.
They are named gastropods because it appears as if they
move along on their stomach (Hickman et
al, 2009).
Order
Stylommatophora:
This order includes land-dwelling, air-breathing snails
and slugs. Two
characters that distinguish the order Stylommatorphora include a
long pedal gland that is located under a membrane and two pairs
of retractile tentacles (Nordsieck).
Family Polygyridae:
Polygyrid snails are classified together because of three
characters. The
first is a missing dart apparatus that is normally used in
courtship. The
second is that the muscles that allow the eyes and pharynx to be
retracted have formed into one band instead of being two
separate bands of muscle.
The last is that their jaws are ribbed.
