WHAT DOES PERIOSTRACUM MEAN IN ENGLISH?

periostracum

Periostracum

The periostracum is a thin organic coating or "skin" which is the outermost layer of the shell of many shelled animals, including molluscs and brachiopods. Among mollusks it is primarily seen in snails and clams, i.e. in gastropods and bivalves, but it is also found in cephalopods such as Allonautilus scrobiculatus. Periostracum is an integral part of the shell, and it forms as the shell forms, along with the other shell layers. Periostracum is visible as the outer layer of the shell of many molluscan species from terrestrial, freshwater and marine habitats, and may be seen in land snails, river mussels and other kinds of freshwater bivalves, as well as in many kinds of marine shelled mollusks. The word "periostracum" means "around the shell", meaning that the periostracum is wrapped around what is usually the more calcareous part of the shell. Technically the calcareous part of the shell can be referred to as the "ostracum", but that term is only very rarely used.

Definition of periostracum in the English dictionary
