You will learn what a mammal is …
I will always remember who did not
know what a mammal was
Sec 3.4:
The Animal Kingdom
INVERTEBRATE animals VS VERTEBRATE animals
INVERTEBRATE animals VS VERTEBRATE animals
• About 95% of animals are invertebrates
• Invertebrates occupy all terrestrial and aquatic
ecosystems and have existed for hundreds of
millions of years
• Invertebrates are divided into 34 phyla, but we
will look only at a couple of them in this course
Invertebrates
1. Sponges and Cnidarians
2. Worms
3. Molluscs
4. Echinoderms
5. Arthropods
1.

Chelicerates
Myriapods
Crustaceans
Insects
Sponges and Cnidarians
SPONGES
CNIDARIANS
Two layers of cells
Asymmetrical
Radial symmetry
Independent and individual cells
(separate them and they will
reassemble)
No tissue
Tissue
Sessile
Trap food particles in water as water
passes through body
Capture prey with stinging tentacles
around mouth
Hydras, jellyfish, sea anemones and
corals
Molluscs
•
•
•
•
•
•
Bilateral symmetry
3 layers of cells
Coelom
2 body openings
Soft body protected by hard shell (most)
Mantle (membrane) surrounds internal organs
• Ex: clams, mussels, oysters, scallops, shelled snails and nonshelled slugs, octopuses and squids
Echinoderms
• Ex: sea stars, sea urchins, sea cucumbers, & sand dollars
• Marine animals
• Radial symmetry
• Spiny endoskeleton (internal skeleton)
• Tube feet (small muscular fluid-filled tubes with suction-cup
like endings)
Anthropods
• Majority of animal species
• Ex: spiders, scorpions, crustaceans, insects
• Jointed foot
• Legs made up of movable sections connected by joints
• Segmented body
• Hard exoskeleton (can shed or molt)
Vertebrates
1. Fish
2. Amphibians
3. Reptiles
4. Birds
5. Mammals
Fish
• Gills to obtain dissolved oxygen from water
• Group 1 – Sharks and rays (skeleton of cartilage)
• Group 2 – boy fish (skeleton of bone)
• Some have a swim bladder (an air sac that allows them to rise
and sink)

Amphibian
• Tetrapods (two pairs of limbs)
• Frogs and Toads / Salamanders
• Have lungs and use moist skin to assist in gas exchange
• External fertilization
• Tied to wet ecosystem
Reptiles
• 3 orders: lizards and snakes/turtles/crocodilians
• Body scales create a waterproof barrier (prevent dehydration)
• Lungs for gas exchange
• Ectothermic: rely on external environment for body
temperature
• Internal fertilization
• Egg and sperm join inside female
• Membrane develop around egg
• Egg deposited in warm environment
Birds
• Evolutionary modified reptiles
• Endothermic: four chamber heart to maintain body
temperature
• Most can fly
• Bones are lightweight and hollow
• Compact body
• Distinctive song-like voices and calls
Mammals – what are you?
Who are you?
Mammals
• Mammary glands (in females) to produce and secretes milk for
nourishing young
• Have hair (insulation, camouflage, waterproofing and
communication)
• Endothermic
• Momotremes (egg laying) / marsupials (pouched) / placental
(have a placenta)
