What causes the growth ridges on the shells of bivalves?
Growth ridges on the shells of bivalves are caused by seasonal changes in their growth rate. During periods of slow growth, the ridges become more pronounced, while faster growth results in smoother areas on the shell. These ridges are a natural part of the shell growth process and can be used to determine the age of the bivalve.
How do you determine the age of a shell?
The thickness of the shell (lip) increases with the age. This is how you can determine the age of the conch.
What is the function of the tooth like projections at the inner dorsal edge of the valves?
The tooth-like projections at the inner dorsal edge of the valves, often referred to as denticles or hinge teeth, serve to interlock the two valves of a bivalve shell. This interlocking mechanism helps to maintain shell alignment and stability when the shell is closed, providing structural support and aiding in the protection of the soft body inside. Additionally, these projections can assist in the prevention of predation by making it more difficult for potential predators to pry the shell open.

Which shell can open and close?
The shell that can open and close is typically associated with bivalve mollusks, such as clams and oysters. These shells consist of two hinged parts (valves) that can be opened to allow the organism to feed or breathe and closed for protection against predators and environmental threats. The opening and closing mechanism is facilitated by a group of muscles that control the shell's movement.
What is the name of A clam or oyster whose body is inside a two part shell?

What type of skeleton does a bivalve have?
A bivalve has a shell made of calcium carbonate, which consists of two hinged valves that protect the soft body inside. They lack a true internal skeleton like vertebrates.
