Isognomon [Isognomon]

Description

Isognomon is the type genus of the family Isognomonidae, widely known as the Pilgrim Oysters. Members of this genus are characterized by their distinctively thin and elongated shells, which have a somewhat triangular shape. These bivalves are often found attached to hard substrates in tropical and subtropical marine environments, forming clusters. They are filter feeders, using their gills to capture plankton and organic particles from the water. The coloration of their shells can vary significantly, from shades of brown to vibrant greens and even purples, often depending on their specific habitats.
