Phylum Proferifera
• Aquatic
• Lack tissues and organs
• Motile larvae
• Sessile adults
• Filter feeders
• Skeleton made up of spongina and/or spicules
• Dead end phylum
Examples: Venus’ Flower Basket, Bath Sponge, Tube Sponge

List
Phylum Cnidaria• Either a Medusa
shape, like jelly fish, or a polyp, like coral
• Still very simple filter feeders
• Open circulatory system,
• No brain. • Oxygen comes from
the water around them.
• Kill prey with toxins that paralyze the body
Back
Classes:
Hydrozoa: Hydras, both polyp and medusa
Scyphozoa: Jellyfish, medusa
Anthozoa: Polyps, sexual & asexual

Phylum Platyhelminthes
• Flatworms• Some are parasites• Some are free living• Single opening system• Circulatory and
respiratory systems not developed
• Can enter sponges or Cindarians
• Cephalization

Beef tapewormClasses
Turbellaria: Free living, flat worms
Trematoda: External & internal parasites, flatworms
Cestadoa:Tapeworms, have a head
Phylum Nematoda§ Round worms§ Don’t have a brain§ Two opening
system: Mouth and Anus
§ Reproduce sexually§ Breath through body
walls§ Do not positively
affect humans§ Bilateral symmetry
Back
Tail of a hookworm
Phylum Mollusca
• Soft bodies with internal or external shell
• Four basic parts: Foot, mantle, shell, visceral mass
• External fertilization• Excrete through an
organ called the nephridia
• Very intelligent• Use gills for breathing• Solid waste
Back
Classes
Plecypoda- Bivalves, open circulatory
Gastropoda- Gastropods, some terrestrial
Cephalopoda- Closed circulatory

Phylum Annelida
• Round• Worm-like animals• Segmented• Two opening digestive
system• Closed circulatory
system• Variety of colors• Bilateral symmetry• Ventral nerve cord
down center of body
Back
LeechClasses
Polycheata: Marine worms, long bristles
Oligochaeta: Earthworms, few bristles
Hirudinea: Leeches, carnivorous, parasitic
Phylum Anthropoda• Tough exoskelton• Jointed appendages• Open circulatory system• Well-developed brain• Segmented body
Back
SubphylumsSubphylums
Chelicerate: Two-part body, chelicerea
Crustacea: Hard exoskeleton , two pair antenna, mandibles
Uniramia: One pair antenna, unbranched appendages
Uniramia ClassesUniramia Classes
Chilopoda: Carnivorus with posin claws, long worm-like body, lots of legs
Diplopoda: Worm like body, lots of legs, not carnivorus
Insecta: Body has three parts and three pairs of legs, mandibles, societies

Phylum Chordata
• Notochord, sometimes replaced with a backbone
• Pharyngeal gills during some part of development
• Hallow dorsal nerve cord
• Closed circulatory system
• Two sets of paired appendages (limbs)

Fishes
Amphibians
Reptiles
Birds
Mammals
Fishes• Two chambered heart• Scales and fins• Pharyngeal gills• Excretion through
gills• Respiration through
gills and swim bladder
• Advanced nervous system
• Lay eggs
Classes
Cephalaspidomorphi: Larve are filter feeders and adults are parasites
Chondrichthyes: Bony endoskeleton
Osteichthyes: Live in salt water, endoskeleton of cartlage
Back
Amphibians
• Adapted primarily to life in wet places
• Ectothermic• Most are carnivorus• Moist, smooth skin• Lay eggs• Internal fertilization• Adults either
aquatic or terresterial
Back
Orders
Urodela:Salamanders
Anura: Frogs and toads
Apoda: Legless amphibians
Click for movie
Reptiles
• Adapted to terresterial life
• More advanced then amphibians
• Dry, scaled skin• Amniotic eggs has
a hard outer shell• Three to four
chambered heart

surface• Scales on legs and
feet• Hollow bones• Four chambered
heart• Well developed lungs
and air sacs• Internal fertilization
