Paracentrobia 🔍
Paracentrobia is a class of bivalve mollusks. They are characterized by their ability to form calcified shells and have two main groups, Paracanthidae (which include the clams, mussels, and oysters) and Paracarinae (including the sponges). These bivalves have a simple, streamlined body with an external shell that is composed of hard, calcified tissue.
