Chapter 23
The groups that make up the protostomes – Ecdysozoans: shed or molt exoskeleton
periodically (Arthropods & Nematods)/Lophotrochozoans: special feeding structure
called a lophophore (Platyhelmids, Annelids, Mollusks)
Body cavities
No Coelum
Psuedocoelum or “False” Coelum: body cavity not completely made of tissue from the
True Coelum: body cavity completely covered in tissue from the mesoderm
Identify the phylum by figure (diagrams). Annelida, Mollusca, Arthropoda, Nematoda,
and Echinodermata
This animal belongs to which group? (pictures) Annelida (Segmented Worms-Olys, Poly,
& Leeches), Mollusca (Gastropods-snails, Bavalvias-oysters, clams, scallops, & mussels,
Cephlapods-squids & octopuses), Arthropoda (Insects, Arachnids-spiders & ticks, &
Crustaseans-crawfish, crabs, shrimp, & lobsters), Nematoda (Roundworms-Trichella &
Heartworms), and Echinodermata (Sea stars, Sea urchins, & Sea cucumbers)
Identify phyla by their members . Annelida (Segmented Worms-Olys, Polys, & Leeches),
Mollusca (Gastropods-snails, Bivalves-oysters, clams, scallops, mussels, Cephlapods-
squids & octopuses), Arthropoda (Insects, Arachnids-spiders, ticks, Crustaceans-crawfish,
crabs, shrimp, & lobsters), Nematoda (Roudworms), and Echinodermata (Sea star, Sea
urchins, & Sea cucumbers)
Identify the phylum by characteristics: Annelida (segmented, closed circulatory system w
5 hearts, excretory system with pharynx & excretory flame cells, nephridia, true coelom),
Mollusca (marine, soft bodies w hard shell, ganglia, open circulatory system w hemocoel,
body plan w mantle & foot), Arthropoda (exoskeleton, compound eyes, respiratory
system w gills, book lungs, & a trachea, hemocoel, segmented w head, thorax, &
abdomen, go through metamorphisis), Nematoda (live in moist or aquatic environments,
psuedocoelom w hydrostatic skeleton, complete digestive system w a mouth & anus), and
Echinodermata (no cephalization, no segmentation, no excretory system, no circulatory
system, primitive nervous system, mairne, endoskeleton made of CaCO3,
spiral/determinate cleavage)
Protostomes: spiral/determinate cleavage (Ectotrophozoans & Lophotrophozoans) and
Deuterostomes: radial/indeterminate cleavage (Echnidoderms)

Hagfish and lamprey characteristics (similarities and differences)
Neither have vertebrae. Lamprey’s have jaw.
Diversity of fish (cartilaginous and bony), amphibians, and reptiles (characteristics)
Cartilaginous Fish-cartilage & jaws
Bony Fish (Ray-finned fishes, celocanths, & lung fishes): bones & jaws
Amphibians: live on land & in water
Reptiles: less reliant on water
Diversity of fish (cartilaginous and bony), amphibians, and reptiles (members)
Amphibians: frogs
Reptiles: snakes, lizards, birds
Mammals – characteristics, groups, members
Produce milk just in diff ways.
Montremes: found in Austrailia & New Guinea
Marcupials: have a pouch with nipples where animals grow and get milk
Placental (40% Rodents, 20% Bats): complete embryonic dev b4 birth
