3 WHAT TYPE OF SYMMETRY? RADIAL ALL IMAGES: GOOGLE.COM/IMAGES

4 HOW DO THEY MOVE? TUBE FEET EACH ARM HAS HUNDREDS OF TUBES SUCKERS TO NAVIGATE WATER VASCULAR SYSTEM

5 SYSTEMS

6 WATER VASCULAR SYSTEM? LOCOMOTION FOOD & WASTE TRANSPORTATION RESPIRATION

7 NERVOUS SYSTEM PRESENT IN ENTIRE BODY SENSORY CELLS GATHER INFORMATION ABOUT SURROUNDINGS NERVE RING HELPS COORDINATE MOVEMENT EYE SPOTS DETECT LIGHT

8 DIGESTIVE SYSTEM ONE-WAY (ANUS AND MOUTH) PUSH STOMACH OUTSIDE BODY EAT DECOMPOSING ANIMAL OR PLANT DIGEST EXTERNALLY

9 EXCRETORY SYSTEM PRESENT OSMOSIS/DIFFUSION RID BODIES OF NITROGENOUS WASTE WATER VASCULAR SYSTEM NO KIDNEYS

10 CIRCULATORY SYSTEM OPEN/OSMOSIS/DIFFUSION NO TRUE HEART WATER PUMPED THROUGH BODY CILIA CIRCULATES FLUIDS FLUID-FILLED CANALS FOR GAS EXCHANGE

11 RESPIRATORY SYSTEM DIFFUSION/OSMOSIS GILLS, CUTANEOUS, LUNGS TAKE IN OXYGEN & PASS OUT CO2 WATER VASCULAR SYSTEM

12 SUPPORT OR SKELETAL SYSTEM ABSENT ENDOSKELETON COVERED BY EPIDERMIS OSSICLES FIT CLOSE AND LOOSE

13 REPRODUCTIVE SYSTEM SEXUAL MORE COMMON TWO-THREE YEARS RELEASE EGG/SPERM INTO WATER FEMALE CAN RELEASE 100 MILLION EGGS CAN REGROW

14 ASTEROIDEA SEA STARS 5-40 ARMS CENTRAL DISK CIRCULAR TO PENTAGONAL TUBE FEET AS SENSORY RECEPTORS

15 OPHIUROIDEA BRITTLE STARS, BASKET STARS, SNAKE STARS 5-10 ARMS RARELY MORE THAN 5 ARMS LENGTH SEVERAL TIMES DISK DIAMETER DISK DIAMETER FROM 3MM TO 150MM

16 ECHINOIDEA SEA URCHINS, HEART URCHINS, SAND DOLLARS LACKING ARMS HAVE A SPINY SHELL TEST MADE FROM FUSED SKELETAL PLATES

17 CRINOIDEA SEA LILIES, FEATHER STARS STALKED, DETRITUS-FEEDING, AND SESSILE AT LEAST 10 ARMS SEA LILIES UP TO 40 ARMS FEATHER STARS UP TO 200 ARMS

18 HOLOTHUROIDEA SEA CUCUMBERS LIE ON SIDES SKELETON REDUCED TO OSSICLES EMBEDDED IN SKIN NO ARMS, TUBE FEET AROUND MOUTH FORM CIRCLE OF 10-30 TENTACLES

19 “SPINY SKINNED”? LITERAL SPINY SKIN MADE FROM CALCIUM CARBONATE FOR PROTECTION CAN CONTAIN POISON

20 WHERE DO THEY LIVE? MARINE ENVIRONMENTS SALT WATER OCEANS SHALLOW TIDE POOLS
