____________________________________________________________________
Porifera : - ex. fan sponges, cup sponges, tube sponges, glass sponges- Mouth/ anus: none
- Symmetry: none
- Skeleton: internal spicules (skeletal needles)
- Other: many pores over the surface through which water is drawn in for filter feeding. Very varied shapes
___________________________________________________________________
Arthropoda : - ex. insects, arachnids, crustaceans, myriapods- Mouth/anus: both
- Symmetry: bilateral
- Skeleton: external skeleton made of plates of chitin
- Other: Segmented bodies and legs or other appendages with joints between the sections
____________________________________________________________________
Mollusca :
- ex. bivalves, gastropods, snails, chitons, squid, octopus
- Mouth/anus: both
-Symmetry: bilateral
-Skeleton: most have shell made of CaCO3
Other: A fold int eh body wall called the mantle secrets the shell. A hard rasping radula is used for feeding

Mollusca
- Have open circulatory system.
- have bilateral symmetry
- Little segmentation
- Have kidney like organs for excretion
- Are mostly with shells
- Have a foot for moving around
Eg- octopus, Unio
Arthropoda
- Arthropod means jointed legs.
-Largest group is animals.
-Have bilateral symmetry.
- Open circulatory system.
-Coelomic cavity is blood filled.
Eg - Housefly, butterfly
Porifera
- Porifera means organisms with pores.
- they are non-motile
-Attached to some solid support
- have pores or holes all over the body which leads to a canal system that helps in circulating water throughout the body.
-commonly called sponges.
Eg - Sycon, Spongilla
