4 Polychaetes Representative Annelids Oligochaetes Marine worms Hirudineans Terrestrial & aquatic Leeches - Aquatic & terrestrial
5 Annelid Circulatory, Respiratory & Excretory Organs Closed Circulatory System Parapodia: Gill-like function Polychaete Nephridia Excretion & selective resorbtion of water & salts Oligochaete
6 Closed Circulatory System Parapodia: Gill-like function Polychaete Oligochaete
7 Nephridia Excretion of nitrogenous wastes Excretion & selective resorbtion of water & salts

13 Mollusca clams snails slugs squids octopuses nudibranchs
14 Adaptive Radiations Triggered by invasion of new habitat, adoption of a new nitch, or by Key Innovation.
15 Primitive Molluscan Body Plan Unsegmented, coelomate Coelom limited to small spaces around nephridia, heart, and intestine Principal body cavity is a hemocoel (open circulatory system) Large, well-defined muscular foot Head and foot ventrally Viscera concentrated dorsally Body covered by a thick epidermal organ - Mantle Mantle cavity houses the ctenidia, osphradia, nephridiopores, gonopores, and anus Mantle secretes shell Buccal region has a radula Trochophore larva Chambered heart Reduced coelom Shell Preoral tentacles Mantle 2 gills Posterior mantle cavity Radula Muscular foot
16 Body wall, shell and mantle
17 Body plan of five classes
18 Mollusca: Radula Feeding Mechanism Drilling carnivore Herbivore Secondary reduction or loss in Cephalopods & Bivalves
19 Another innovation Counter current gas exchange Ciliary gill
20 Molluscs: Nervous & Organization Slow crawlers - varied diets Primitive ladder-like nervous system (polyplacophran) No spinal ganglia Gastropod nervous system Cephalopod brain Active predators Pelecypod nervous system Stationary filter feeders Squid: giant axons
21 Creeping Varied diets Jet-propelled Armed predators Living fossils Burrowing Filter feeders Reign of Ammonites Benthic creepers Algae feeders Aplacophora Worm-like burrowers Detritus feeders (Modified from Hickman & Roberts, 1995)
22 Anatomy of aplacophorans Worm-like, burrowing or epibenthic Shell-less Radula present Small mantle cavity with gills Similar to ancestral group
