What are Mollusks?
Mollusks are a large group of soft-bodied animals found in both water and on land. Most mollusks have a shell that protects their body, but some, like octopuses and squids, do not. They are one of the oldest and most diverse groups of animals on Earth.
Examples:
- A clam lives inside two shells.
- An octopus uses eight arms to catch food.
Characteristics of Mollusks
- Soft body (protected by a shell in most species)
- Bilateral symmetry (left and right body sides are equal)
- Body parts include: foot, mantle, and visceral mass
- Most are aquatic but some (like land snails) live on land
- Nervous system ranges from simple (clams) to advanced (octopuses)
Major Types of Mollusks
1. Gastropods
Largest group of mollusks
Usually have a spiral shell (except slugs)
Examples → Garden Snail, Sea Slug, Limpet
2. Bivalves
Have two shells joined together
Mostly filter feeders that live in water
Examples → Clam, Mussel, Oyster, Scallop
3. Cephalopods
Intelligent mollusks with tentacles and advanced eyes
Can change color and squirt ink for defense
Examples → Octopus, Squid, Cuttlefish, Nautilus
4. Polyplacophora
Marine mollusks with eight hard plates on their back
Example → Chiton
5. Scaphopods
Tubular shells shaped like elephant tusks
Example → Tusk Shell
6. Monoplacophora
Primitive mollusks with a simple cap-like shell
Example → Neopilina
7. Aplacophora
Worm-like mollusks without shells
Examples → Solenogaster, Caudofoveate
