_____________________________ is made up mostly of Cnidarians and Porifera. Cniarians in their polyp stage will attach to any surface on the ocean floor. As they grow, they construct a hard inner structure and surround it with a soft body. When Cniarians die, the soft tentacles disintegrate but the hard structure is left behind.

All animals in phylum mollusca contain a think muscular ‘______________________________’

This features helps them to open and close their shell, eat, move, or to burry into the sand.

The 3 Classes of Phylum MolluscaClass

Gastropoda“Stomach foot”

Examples:

How do they move?Tiny cilia on bottom of the

stomach foot.Produce mucus to slide on.

ClassBivalvia

“Two Shells”

Examples:

How do they move?

Opening and closing their shell to squirt water

ClassCephalopoda

“Head foot”

Examples:

How do they move?

Tentacles &

Jet propulsion

Pearls are formed when a small grain of sand gets stuck between the muscular foot and the shell of an oyster. The oyster covers the foreign object with layers upon layer of a shiny secretion.
