Mollusca

Characteristics • Soft-bodied animals that typically have shells (for protection) • Can live on land or in water(fresh or ocean) • reproduce sexually • bilateral symmetry

These are mollusks!!!!!

Gastropods "stomach foot" Ex. snails and slugs • largest group of mollusks • Move using a muscular foot and by oozing mucus

• Body Systems *simple nervous system *open circulatory system

• Body Plan/Function *single or no shell *radula in mouth (files off bits of plant matter into small pieces) Radula types

Bivalves Two-Shelled Mollusks Ex. Clams, Oysters, Scallops and mussels

• Habitat/Movement *live in water *some move by clapping shells together

§Body Systems *simple nervous system *open circulatory system

§Body Plan/Function * filter feeders (as water passes over body, it filters out small organisms)

Cephalopods “Head Foot” Ex. octopus and squid

Habitat/Movement *live in water · *tentacles used for movement and to capture food *Some have ink glands, release when alarmed for camouflage

Body Systems • *Most elaborate nervous system in Mollusk phylum *have brain *closed circulatory system
