Domain Eukarya
Kingdom Animalia
•Eukaryotic
•Multicellular
•Nucleus with no cell wall
•Motile at some point
•Consumer
Important vocabulary• Symmetry – how organism
is divided Radial – same in all
directions Bilateral – two sides similar• Coelom – body cavity Acoelomate – no coelom Pseudocoelomate – lined on
one side with tissue Eucoelomate – lined on both
sides with tissue• Cephalization - Sense
organs are in one area• Blastopore – early
developmental stage
• Tissue layers - # of tissues (and what it becomes)
Endoderm -inner Ectoderm- outer Mesoderm -middle• Gut – digestive organs Gastrovascular cavity complete (mouth to anus) • Segmentation – is body in
repeated sections• Cleavage Spiral - Protostome Radial - Deuterostome

Phylum to Know• Porifera – sponges• Cnidaria – sea anemones, corals, jellyfish• Platyhelminthes- flatworms• Nematoda – roundworms• Annelida – segmented worms (earthworms)• Mollusca – snails, shellfish, slugs• Arthropoda – insects, crustaceans, spiders• Echinodermata – sea urchins, sea cucumbers• Chordata - fish, amphibians, birds, us• Others mentioned – Ctenophores, Rotifers,
Hemichordata
Phylum Porifera - Sponges
• Multicellular• Asymmetrical – no
symmetry• No body tissues
• Skeleton of CaCO3 or silica
• Filter feeder• Hermaphroditic• Can reproduce asexually
by splitting or budding
Phylum Cnidaria – Corals, jellyfish• Radial symmetry• 2 tissue layers (endo,
ectoderm, mesoglea)• Gastrointestinal sac• Hermaphroditic• Can reproduce
asexually by budding or splitting (coral)
• Stinging cells (Nematocyst)
Phylum Platyhelminthes - flatworms• Bilateral symmetry• 3 tissue layers• Acoelomate• Gastrointestinal sac• Some cephalization• Can reproduce
asexually by fission (splitting)
Phylum Nematoda - roundworms• Bilateral symmetry• 3 tissue layers• Psuedocoelomates• True gut – mouth to
anus• Most separate sexes
Phylum Annelida – segmented worms• Bilateral symmetry• 3 tissue layers• Euceolomate• Complete gut – mouth
to anus• Cephalization• Segmented• Spiral cleavage –
Protostome• Blastopore forms
mouth
Phylum Mollusca – Clams, snails, squid• Bilateral symmetry• 3 tissue layers• Euceolomate• Complete gut – mouth to anus• Cephalization• Segmented• Spiral cleavage –
Protostome• Blastopore forms
mouth• Shelled- 1 or 2 (some
lost or internal)
Phylum Arthropoda – Insects, spiders, crabs
• Bilateral symmetry• 3 tissue layers• Euceolomate• Complete gut – mouth
to anus• Cephalization• Segmented• Spiral cleavage –
Protostome• Blastopore forms
mouth• Exoskeleton of chitin
Phylum Echinodermata - sea star, sea urchin
• Bilateral symmetry• 3 tissue layers• Euceolomate• Complete gut – mouth to
anus• Cephalization• Segmented• Radial cleavage –
Dueterostome• Blastopore forms anus• Pentamerous symmetry as
adult• Asexual and sexual
reproduction
Phylum Chordata – lancelets, sea squirts, us• Bilateral symmetry• 3 tissue layers• Euceolomate• Complete gut – mouth to anus• Cephalization• Segmented• Radial cleavage –
Dueterostome• Blastopore forms anus• Notochord – spine, skull• Dorsal hollow nerve chord –
spinal cord, brain• Pharyngeal gill slits - pharynx• Post-anal tail - coccyx
Chordate sub phylum• Urochordata• Sea squirt or
tunicate• Sessile as
adult
• Cephalochordata• Lancelet
• Vertebrata• Includes 6/7
classes• Agnatha• Chondrichtyes• Osteicthyes• Amphibia• Reptilia• Aves• Mammalia
Class Agnatha – jawless fish
• Skull• Lack jaws Hagfish Lampreys
Class Chondricthyes – cartilaginous fish
• Cartilaginous skeleton• Jaw sharks skates rays
Class Osteicthyes – bony fish• Skeleton of bone Tuna Salmon All other
familiar fish
Class Amphibia – Salamanders, toads, frogs, caecilians
• Four walking legs• Water as young,
land as adult• Needs water for eggs• Moist skin
Class Reptilia – Snakes, lizards, turtles, tortoise, crocidilians, tuataras
• Scaly skin• Lungs• Claws• AMNIOTIC EGG
Amniotic egg
Class Aves - birds• Feathers• Endotherm – steady
internal body temp.• Wings• Toothless beak
Class Mammalia – horses, us
• Fur• Mammary glands –
milk• 4 chambered heart• Endotherm Monotreme – egg
laying Marsupial – pouched Placental – live birth
with placenta
