Vetikese

Vetikese is a genus of small, marine snails belonging to the family Littorinidae, commonly known as periwinkles. These gastropod mollusks are typically found in intertidal zones of temperate and boreal regions worldwide, often adhering to rocks, seaweed, and other hard surfaces. The shells of Vetikese species are generally conical or ovate, with a relatively thick, often ribbed or sculptured exterior. Their size is usually modest, rarely exceeding a few centimeters in length.

The diet of Vetikese snails primarily consists of algae and diatoms scraped from surfaces using their radula. They play a significant role in intertidal ecosystems as grazers, influencing algal growth and community structure. Like other periwinkles, Vetikese often exhibit distinct zonation patterns within the intertidal area, with different species occupying specific height ranges influenced by factors such as desiccation tolerance and predation pressure.

Reproduction in Vetikese species typically involves broadcast spawning, where males and females release gametes into the water column. Larval development is planktonic, with the young snails eventually settling on suitable substrates to begin their benthic existence. Several species within the Vetikese genus are well-known and widely distributed, serving as common examples of intertidal life. Their ecological importance and accessibility have made them subjects of study in marine biology and ecology.
