An acorn barnacle is a type of barnacle that has a cone-shaped shell directly attached to rocks or other hard surfaces. They lack a stalk, unlike goose barnacles, and are permanently cemented in place. These barnacles are common in intertidal zones, enduring waves and exposure. Think of them as tiny, rocky castles🏰. They filter feed using feathery appendages that extend from their shell. Acorn barnacles are essential parts of the marine ecosystem, often competing for space.
