Propebela Pribilova
''Propebela pribilova'' is a species of sea snail, a marine gastropod mollusk in the family (biology), family Mangeliidae. Description The length of the shell attains 12 mm, its diameter 5.5 mm. (Original description) The white shell has a straw-colored periostracum. It contains about six roughly sculptured Whorl (mollusc), whorls, the Apex (mollusc), apex eroded. The suture is distinct. The axial Sculpture (mollusc), sculpture consists of (on the body whorl 16) rounded narrow riblets crossing the whorls and obsolete on the base. The spiral sculpture consists of (on the Spire (mollusc), spire three, on the body whorl four) prominent rounded cords. These are more or less nodose at the intersections with the ribs, and between the cords two or three fine threads and a few finer striae. The posterior cord forms a shoulder to the whorl. On the siphonal canal the cords and threads become more uniform. The Aperture (mollusc), aperture is simple. The Columella (gastropod), col ...

Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails. Anatomy Sea snails are a very large group of animals and a very diverse one. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species includ ...
