Cylista
Cylista is a genus of marine bivalve molluscs in the family Cyclidae. They are commonly known as “Cylista clams” or “Keyhole Limpets.” These molluscs are characterized by their distinctive shell morphology, which resembles a keyhole with a small opening at the apex.
Characteristics
Cylista species are typically small, with shell sizes ranging from a few millimeters to a few centimeters. The shells are generally oval or elongated in shape, with a smooth or slightly sculptured exterior. The keyhole-shaped opening at the apex of the shell is a unique feature that distinguishes them from other bivalves. This opening serves as an outlet for water and waste products. The shells can exhibit a variety of colors, including white, gray, brown, and reddish-brown.
Environment
Cylista clams are found in a variety of marine environments, including rocky shores, sandy beaches, and coral reefs. They are typically found in intertidal zones and shallow subtidal areas. These clams are often found attached to rocks, shells, or other hard substrates. Their diet consists primarily of algae and detritus, which they filter from the water using their gills.
Distribution
Cylista species are found worldwide in temperate and tropical waters. They are particularly abundant in the Indo-Pacific region.

The genus Cylista includes several species, some of the most notable include:
