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

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

SYSTEMS

WATER VASCULAR SYSTEM? LOCOMOTION FOOD & WASTE TRANSPORTATION RESPIRATION

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

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

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

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

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

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

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

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

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

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

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

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

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

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