SPINES PEDICELLARIA SKIN GILLS Image by Riedell
SPINY SKIN http: //wwwbio 200. nsm. buffalo. edu/labs/tutor/Starfish SPINES for protection connect to ENDOSKELETON inside underneath skin
OSSICLES Calcium carbonate plates form endoskeleton inside http: //ebiomedia. com/prod/BOechinoderms. html
SPINES PEDICELLARIA SKIN GILLS Image by Riedell
PEDICELLARIAE (sing. Pedicellaria) http: //www. discoveringfossils. co. uk/echinoid_pedicillaria. jpg http: //attleborobio. blogspot. com/2008/04/weekly-urchin-pedicellariae. html Keep surface clear of organisms
SKIN GILLS Hollow skin tubes that project from skin for increased surface area connect to coelom inside Image by Riedell
Skin gills between spines http: //wwwbio 200. nsm. buffalo. edu/labs/tutor/Starfish EXCHANGE GASES and EXCRETE NITROGEN WASTE
TUBE FEET surfaces http: //wwwbio 200. nsm. buffalo. edu/labs/tutor/Starfish Can exchange gases and excrete nitrogen waste

GONADS
http: //wwwbio 200. nsm. buffalo. edu/labs/tutor/Starfish/ AMBULACRAL RIDGE covered by OSSICLES contains RADIAL NERVE (nervous) and RADIAL CANAL (water vascular system)
AMBULACRAL RIDGE AMPULLAE (tops of tube feet)
NERVOUS SYSTEM follows WVS Image by Riedell NERVE RING encircles mouth RADIAL NERVES run inside AMBULACRAL RIDGE in each arm
SEPARATE SEXES GONADSreproductive organs Starfish have both SEXUAL ASEXUAL (Regeneration)

DIGESTIVE GLAND GONAD OSSICLES
MOLLUSKS (some ANNELIDS) Have a TROCHOPHORE LARVA http: //www. okc. cc. ok. us/biologylabs/Images/Evolimages/trochophore. JPG
SEXUAL REPRODUCTION FERTILIZATION EXTERNAL DEVELOPMENT INDIRECT LARVA BIPINNARIA Has BILATERAL SYMMETRY and wings to swim
ASEXUAL REPRODUCTION Ability to self amputate AUTOTOMY Ability to regrow lost parts REGENERATION http: //users. rcn. com/jkimball. ma. ultranet/Biology. Pages/R/Regeneration. html
