What are the common molluscs?

Molluscs are the largest class of invertebrates. They usually have no bones and hard shells, and their bodies are soft and easily deformable. Here are some common molluscs:

1. Snail: A snail is a widespread mollusk that usually has a spiral shell.

2. Clams: Clams are bivalve molluscs that have two hard shells that can be opened and closed to protect themselves.

3. Turtle snail: Turtle snail is a kind of marine mollusk. It usually has a shell with beautiful colors and is a common cultural art material.

4. Cyprinus: Cyprinus are tentacle-like molluscs that confuse predators by releasing ink.

5. Squid: A squid is a mollusk with eight arms and two tentacles on its head. They can spray water to escape danger.

6. Octopus: Octopuses are also molluscs with eight arms on their heads, and they can camouflage themselves with the colors and textures of their surroundings to hide from predators.

7. Spirulina: Spirulina is a single-celled mollusk that usually grows in fresh or seawater and is widely used in the preparation of nutritional supplements.

It's important to note that although many species of these molluscs are small, they play important roles in both marine and terrestrial ecosystems.
