1. So What!? To help us remember how they are classified.
Animal Phyla (pg )
Is about Distinguishing characteristics used to classify animals into 6 phyla.
Cnidarians
Live in aquatic environments.
Have stinging cells
2 stage life cycle
Coral, Jellyfish, Hydra, Anemone
Annelids
Have a simple nervous system with a ganglia for control (group of nerves, like a simple brain)
Have a simple circulatory system to pump blood.
Have a Digestive System to break down food.
Segmented worms – Earth Worms, Leeches, Bristle Worms
Mollusks
Soft Bodies (some covered by shells)
Open circulatory system (loose blood sloshing)
Gastropods (Snails)
Cephalopods (Squid and Octopus)
Bivalves (Clams, Oysters, and Muscles)
Arthropods
Means “Jointed Foot”
Have an Exoskeleton (like a suit of armor over it’s entire body)
Largest and most divers group
Crustations, Arachnids, Insects, millipedes and centipedes.
Echinoderms
Means “Spiny Skin”
Have a hydrostatic skeleton
All live in Aquatic Environment and have radial symmetry
Sea Stars, Sea Cucumbers and Sea Urchins
Chordates
Have a notochord
In most, notochord becomes the backbone
Cold Blooded - Fish, Reptiles and Amphibians
Warm Blooded - Birds and Mammals
So What!? To help us remember how they are classified.

2. Animal Kingdom Characteristics
1. Multicellular – all animals have many cells, some (like us) have trillions of cells Reproduce sexually – Two parents each contribute ½ of the DNA through egg and sperm Move – Most animals walk, swim, crawl, climb, or fly Some only move a tiny bit when they are first born and then sit still for the rest of their life Specialized Parts – many cells mean some can do different jobs. Multicellular organisms can be more complex 5. Consumers – Animals need to eat food to get energy. They convert food to chemical energy (ATP) in their Mitochondria. 6. Maintain Body Temperature – Animals work best when they keep their temperature. Some warm and cool themselves. Some need to find a warm space (or a cool space) to maintain their temperature.
