Anoodids

Anoodids are a group of marine bivalve mollusks belonging to the family Anoodontidae. They are characterized by their distinctive, tooth-like structures on the shell, which are used for scraping algae and other food sources from rocks. Anoodids are found in shallow waters around the world, particularly in the Indo-Pacific region. They are sessile filter feeders, attaching themselves to rocks or other hard surfaces using a byssal thread. Their shells are typically small to medium-sized, ranging from a few millimeters to several centimeters in length. Anoodids play an important role in marine ecosystems by helping to control algae growth and contributing to the overall biodiversity of their habitats. Despite their ecological significance, they are not well-studied and much remains unknown about their biology and behavior.
