Transcript of Animal phylum
Animal Phylum
Animals
What are ANIMALS?
1. Many celled organisms that must get energy by eating other organisms.
a. Herbivores – animals that eat only plants
a. Carnivores – animals that eat other animals
b. Omnivores – animals that eat both plants and animals
Animals
2. Classified based on the presence or absence of a backbone.
a. Invertebrates – no backbone (95 % of all animals)
b. Vertebrates – backbone (only 5% of all animals)
Phylum Cnidaria – “Stinging Cells”
1. Invertebrates
2. All have Stinging cells – nematocysts
3. All marine
4. Simple organisms – just tissue, no organs
5. Examples: a. Jelly fish
b. Coral and Anemones
“Cnidarians”
Cnidarians
Phylum Annelida – Segmented Worms
1. Invertebrates with segmented body parts
2. Bristles (hairs) on body
3. Land and marine
4. Examples:a. Earthworms
b. leeches
“Annelids”
Annelids
Phylum Mollusks – Muscular foot
1. Invertebrates
2. Mantle – shells
3. Land and marine
4. Examples:a. Snails and slugs
b. Octopus and squid
c. clams
“Mollusks”
Mollusks
Phylum Echinodermata – “Spiny skin”
1. Invertebrates – no backbone
2. All Marine
3. Radial symmetry, 5 appendages and tube feet for suction
4. Examples:a. Sea stars, brittle stars
b. Sea cucumbers and sea lilies
c. sea urchins
“Echinoderms”
Echinodermata – “Spiny skin”
Echinodermata – “Spiny skin”
Phylum Arthropoda – “Jointed Appendages”
1. Invertebrates2. Exoskeleton of chitin3. Jointed appendages4. Land, marine and air
a. Most successful of all animals b. 75% of all organisms on earthc. Insects – 6 legsd. Arachnids – 8 legs
5. Examples:a. Insects and spidersb. Crabs and crustaceans
“Arthropods”
Arthropods
King Crab
Phylum Chordata – Backboned animals
1. Vertebrates
2. Endo skeleton – inside of body
3. Land, marine and air
4. Most diverse phylum, many different types
5. Examples: a. Amphibians
b. Fish
c. Reptiles and birds
d. Mammals (humans)
“Chordates”
Chordates
