The Fenestrate Top Shell, scientifically known as Tectus fenestratus, is a species of sea snail that belongs to the family Tegulidae. These marine gastropods are found in various parts of the world and are recognized for their unique shell structure.
Description and Characteristics
The Tectus fenestratus shell is characterized by its distinctive “fenestrated” appearance, which means it has numerous small openings or perforations. This unique feature gives the shell a delicate and airy look. The shell is generally conical in shape and can reach a maximum size of about 50 mm in diameter. The color of the shell varies, with shades of brown, tan, and white being common. The aperture, or opening of the shell, is typically rounded and has a slightly thickened lip.
Habitat and Occurrence
The Tectus fenestratus is a marine snail that primarily inhabits the intertidal and subtidal zones. This species is found in a variety of habitats, including rocky shores, coral reefs, and seagrass meadows. They are most commonly found in the Indo-Pacific region, extending from the Red Sea and the East African coast to the Philippines and Australia. They prefer environments with a moderate amount of wave action and are typically found at depths ranging from the intertidal zone to around 20 meters.
Taxonomy
The species Tectus fenestratus belongs to the Class Gastropoda, Order Trochida, and Family Tegulidae. This classification places it within a large and diverse group of marine snails that share common characteristics, including a spirally coiled shell and a muscular foot used for locomotion.
Feeding
The Tectus fenestratus is an herbivore and primarily feeds on algae. These snails use their radula, a tongue-like structure covered in tiny teeth, to scrape algae off rocks and other surfaces. This feeding behavior plays an important role in the marine ecosystem, contributing to the balance of algal populations and the overall health of the habitat.
