The Pacific Acorn Barnacle is a tiny animal that sticks to rocks and shells in the ocean. They have a hard shell that looks like a little acorn, and they open up to eat tiny food from the water!
生息地: Rocky shores and tidal pools along the Pacific coast.
The Pacific Acorn Barnacle is a small, whitish-grey cone with a rough, often ridged surface. Its top has a diamond-shaped opening made of four movable plates. It looks like a tiny volcano glued to rocks, distinct from smooth, flat limpets.
