Littoraria irrorata, common name the marsh periwinkle, is a species of sea snail, a marine gastropod mollusk in the family Littorinidae. The specific epithet irrorata means 'moistened' or 'dewy.'.

This species occurs in salt marshes on the Atlantic coast and Gulf Coast of North America, from Massachusetts to Texas. Some colonies of this species of snail are the only mollusks known to practice Family: Littorinidae.

Littorina ziczac is a synonym for Echinolittorina ziczac (Gmelin, ) Littorina zonaria Bean, synonym of Littorina saxatilis (Olivi, ) References.

The distribution of Littorina irrorata Say on a low-energy barrier beach on the northern Gulf of Mexico is described, and correlated with the presence of Spartina alterniflora and other plants in the upper intertidal zone.

The movements of 66 individually tagged snails were followed in the S. alterniflora zone for an average of days, during which time an average of positions were Cited by: The growth of the salt marsh periwinkleLittoraria irrorata (collected from Sapelo Island, Georgia ininitial shell length to mm) on various diets was measured.

Summary. The saltmarsh periwinkleLittorina irrorata is well adapted for the digestion of a wide range of polysaccharides. Enzyme extracts attacked cellulose, pectin, xylan, bean gum and mannan (common in cell walls of higher plants), as well as starch and laminarin (representative of major polysaccharide classes in fungal, algal, and animal tissues).Cited by: "The marsh periwinkle Littorina irrorata (Say) occurs in a variety of Spartina marsh settings on St.

The diet of the periwinkle Littorina irrorata was examined. The food substrate utilized most frequently in the field was dead Spartina alterniflora. The primary component of the stomach and feces was vascular plant particles. Plant particles, even though a major portion of the diet, were egested unaltered in feces.

An Approach Using Morphology and Biochemical Genetics by Moyse, J., Thorpe, J. & Al-Hamadani, E. and a great selection of related books, art and collectibles available now at The present study describes some aspects of the morphology of the digestive tract and the feeding patterns of Loricaria lentiginosa.

Sixty-three specimens with gut contents were captured quarterly. When comparing the morphology of the periwinkle on the exposed and the sheltered shore there is clearly a difference which suggests the level of wave exposure has a great effect on the size of the Littorina saxatilis.

The results from the t-test also back up this hypothesis.

Littorinidae definition is - a large nearly cosmopolitan family of snails (suborder Taenioglossa) that have broad conical shells with round aperture and horny operculum, that are chiefly littoral in salt water or brackish or fresh water and are remarkably resistant to desiccation, and that feed on algae.
