Coelomate what is the arrow pointing at?

coelomic (liquid filled space)

Porifera (sponges)

-NA body layers -do not have digestive system (diffusion) -do not have respiratory system -hermaphrodites (but can reproduce asexually by budding) -asymmetrical -Acoelomate -Neither protostome or deuterosome -Locomotion: sessile

Cnidaria

-2 body layers -Single opening for digestion and eating -No respiratory system -Hydro static Skeleton

• Hermaphrodites -Radial symmetry -Coelom -Neither protostome or deuterostome -Locomotion: Sessile, medusa

Platyhelminthes (flat worm)

-3 body layers -single opening for digestion and eating -No respiratory system -Hydro-static skeleton -Hermaphroditic -Bilateral symmetry -Protostome -Locomotion - muscle elongation/contraction, swimming

Nematoda (round worms)

-3 body layers -two openings (mouth to anus) -No respiratory system -hydro static -Sexual and Asexual -Bilateral symmetry -Pseudocoelom -Protostome -Locomotion - Muscle elongation and contraction; Swimming

Annelida (segmented worms)

-3 body layers -Complete digestive tract -Complete respiratory system -Hydro static skeleton -segmented

• sexual and asexual (monoecious or dioecious) -Bilateral symmetry -Coelom -Protostome

Mollusca (mollusks)

• 3 body layers -Complete digestive tract -not segmented -No skeletal system (some have exoskeleton) -Hermaphrodite -Internal or external shells -Bilateral symmetry -Coelom -Protostome

Arthropoda (crustaceans)

-3 body layers -complete digestion with two openings -segmented -Invertebrate- jointed limbs and cuticles; Insects exoskeletons -Sexual -Bilateral -Coelom -Protostome
