Porifera
SPONGES-Parazoa
1.sessile, porous bodies, no true tissue
2.spongocoel-central cavity, water drawn in thru pores
3.osculum-large top opening, water flows out
4.choanocytes-flagellated collar cells trap food in spongocoel
5.amoebocytes-moved thru mesohyl, digest and move nutrients, secrete tough skeletal cells
Cnidaria
JELLYFISH, CORAL-Radiata
1.gastrovascular cavity-digestive sac
2.medusa body plan-flattened, mouth and tantacles down
3.polyp body plan-mouth and tentacles up
4.tentacles-used to catch prey, with cnidocytes
5.Nematocyst-stinging capsules w/icnidocytes
Ctenophora
COMB JELLIES-Radiata
flourescent cilia
Platyhelminthes
FLATWORMS-Acoelmates
1.gastrovascular cavities
2.tripoblastic
3.free-living, marine, and parasitic
4.flame cells-waste removal and water balance
Rotifera
ROTIFERS-Psuedocoelmates
1.jaws, complete digestive tracts
2.crowns of cilia
Lophophorate phyla
Coelmates
lophophore-ciliated tentacles around mouth
Mollusca
SNAILS, SLUGS, CLAMS, SQUID, OCTOPUSES-Coelmates
1.muscular foot
2.visceral mass-organs
3.mantle and cavity-contains visceral mass
4.radula-straplike rasping organ used for feeding
CLASSES:
A.Gastropoda-snails, slugs, marine species, undergo torsion
B.Bivalvia-clams, oysters
C.Cephalopods-squids, octopuses
Annelida
SEGMENTED WORMS-Coelmates
1.coelum-partioned by septa
2.complete digestive tract
3.closed circulatory system
4.cephilization
5.Class polychaete-parapodia, setae
6.Leeches
Anthropoda
BUGS, ETC- Protostomes
1.most variable, prolific, and successful phyla; all habitats
2.body segments, hard exoskeleton, jointed appendages
3.specialization, cephilization
4.exoskeleton-cuticle, protein and chitin, protection, attached to muscles, water-proof, molted
5.open circulatory system-hemolymph fluid
6.4 major evolutionary lineages-trilobites, chelicerates, uniramians, crustaceans
7.larvae-incomplete or complete metamorphosis
Differences in Arthropods' groups
1.chelicerates have clawlike feeding appendages(chelicerae), others have jawlike mandibles
2.chels lack sensory antennae and have simple eys, others have compound and simple eyes
3.unirams have unbranched appendages, crusts have biramous appendages
