Mollusks

These invading mollusks could spread like a cancer.

Gastropods are mollusks.

The Great Barrier Reef Marine Park is about the size of Japan and is so big it can be seen from outer space. It is home to more than 3,000 types of mollusks and 1,600 species of fish.

Mollusks have soft bodies.

Slugs, snails, and octopuses are mollusks.

Snails are mollusks that move slowly.

Slugs, like snails, are hermaphroditic mollusks, who thus have both ovaries and testes.

The largest animal phyla are the arthropods, the mollusks, and the chordates.
