Liotia Evoluta
''Liotia'' is a genus of very small sea snails, marine gastropod mollusks in the family Liotiidae.Bouchet, P.; Rosenberg, G. (2013). Liotia Gray, 1842. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=415570 on 2013-09-07 ''Liotia'' is the type genus of the family Liotiidae. Description The species in this genus are small to minute. They have a depressed or turbinate shape. They are all umbilicated with a nacreous inner layer. The thickened outer lip, attached to the body whorl for a short length, is continuous. Where the operculum has been stated, it is horny and multispiral. Species * ''Liotia admirabilis'' E. A.

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Operculum (gastropod)
The operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails; the structure is found in some marine and freshwater gastropods, and in a minority of terrestrial gastropods, including the families Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyclostrema Cancellatum
''Cyclostrema cancellatum'' is a species of sea snail, a marine gastropod mollusk in the family Liotiidae. Description The size of the shell varies between 8 mm and 15 mm. The white, sublenticular shell is flattened convex above, more convex below. It contains oblique radiating riblets, interrupted by an obtuse peripheral rib The interstices of the riblets are finely spirally striated. The umbilicus has a moderate size. (Description by W.H. Dall) The thin, white shell has a planorboid shape with 3½ whorls. The radiating sculpture consists of about fifteen ridges, faint on the base and summit, making small nodules where they cross the fine spirals, and prominent and strong on the periphery between the three peripheral carinae. Other radiations are only due to lines of growth which are sometimes slightly elevated. The spiral sculpture consists of three prominent and strong peripheral ridges, of which the uppermost forms the chief periphery. The others are slightl ...
