Which phylum does this belong to? Does it have a foot?

porifera cnidarians flatworms mollusks annelids nematodes arthropods echinoderms chordates

Origin of multicellularity

Mollusc - 3 body partsVisceral massFootMantle (may make shell)

Origin of multicellularity

Gastropods - snails, conchs, nudibranchsCephalopods - octopus, nautilus (tentacles)Bivalves - clams, oysters (two shells)

Origin of multicellularity

porifera cnidarians flatworms mollusks annelids nematodes arthropods echinoderms chordates

Origin of multicellularity

Arachnids - no antennae, mandible

- 4 pairs of legs

- spiders, scorpions, ticks

- horseshoe crab

Millipedes, centipedes (many legs)

Arthropods- jointed appendages

- segmented- grow by molting / metamorphosis – CRUNCHY exoskeleton

Insects - head, thorax, abdomen

- 3 pairs of legs (wings)

Crustaceans - forked appendages

- head and thorax fused

- lobsters, crabs, crayfish

- barnacles

- pillbug (land)
