What is an fact about mollusks?
answer 2 Mollusks contribution to the evolution scheme, was to invent the shell, which in later form became the skeleton. Slugs have internalized their shells.With a shell, you now have a rigid point to which you may attach muscles, and thus make complex movements.
What mollusks form pearls?
oysters
What sea animal lives in a sea shell?
Clams obviously live in the clam shells, sea slugs live in the spirial shells. Some of their organs actually form inside the shell. Also, once those die, sometimes hermit crabs take over the shell when they out grow their previous shell. crabs, mollusks, oysters, mussels, clams, scallops, and other creatures
What are seashells made of?
Seashells are primarily made of calcium carbonate, which is a mineral that is also found in corals and pearls. This material is secreted by mollusks such as snails, clams, and oysters to form their shells, providing protection and structure for the soft tissues inside.
Do all mollusks possess a hard external shell?
A mollusk's exoskeleton is composed of chitin (a component of the exoskeleton of most animals) and conchiolin which is a form of calcium carbonate (present in snail shells). These complex proteins are secreted by the mantle layer present right below the shell and hardens over time as the creature grows.
How are seashells formed?
Most mollusks have shells outside their soft bodies. The shell is a mollusk's skeleton. It is part of the animal and the mollusk is attached to it by muscles. The soft animal inside can never leave its shell and come back to it. The shell is made of a form of limestone and is built by the mollusk itself. Certain glands in the mollusk are able to take limestone from the water and deposit it in tiny particles at the edge of, and along the inside of, the shell. As a mollusk grows in size, its shell increases in thickness and size. The shell of a mollusk consists of three layers. The outside is covered with a thin layer of hornlike material that contains no lime. Under this is a layer of carbonate of lime. The inside layer is the "mother-of-pearl", or nacre. It is made up of very thin alternate layers of carbonate of lime and a horny substance. The coloring of the shell comes from some glands of the mollusk that contain coloring matter. So a shell may be spotted, all one color, or marked with lines.
What is a calcareous shell?
A calcareous shell is a hard, protective outer covering made primarily of calcium carbonate, found in organisms such as mollusks, corals, and some types of algae. It serves to protect the organism from predators and harsh environmental conditions.

What is the prismatic layer made of?
The prismatic layer is made of tightly packed, angle-shaped crystalline structure known as aragonite. It is a form of calcium carbonate that provides strength and protection to the shell of certain organisms, such as mollusks and some types of crustaceans.
What is the scientific name for the mollusk sponge?
There is no such nomenclature. Mollusks and sponges are two forms of invertebrates.Some sponges, such as Myxilla incrustans form symbiotic relationships with some mollusks (i.e scallops).
What is the scientific name for Mother of Pearl?
The scientific name for Mother of Pearl is nacre. Nacre is a composite material produced by some mollusks as an inner shell layer. It is composed mainly of aragonite, a mineral form of calcium carbonate.
