spicules means

"little spikes"

sessiles are?

Nematoda

Phylum mollusca means?

soft body (have shells to protect)

Phylum Mollusca have 3 body parts?

Visceral Mass (Internal organs), Foot (Mobility), and Mantle (covers visceral mass and produces shells)

classifications for Mollusca Phylum?

Gastropoda (stomach footed; snails), Cephalopoda (head footed; squid and octopus) and Bivalvia (two shell ; oysters and clams)

Bivalvia hold the two shells together with what muscle? what kind of circulatory system do they have?

adductor muscle (hatchet footed) they have a closed circulatory system so they move slow.
