How many animals do you think there are?

5 of 27

Estimates of 1.5 million recognized, named species of organisms on earth.

It is estimated that there are about 30 million species of organisms on earth, yet we have only identified 1.5 million. (5% of est. total)

Animal Kingdom

Animals are multicellular organisms that are capable of locomotion and rely on other organisms to obtain their nourishment

10 of 27

The animal kingdom is divided into 38 phylums.

Which phylum has the most species???

Arthropoda!

15 of 27

More than 80% of described living animal species are arthropods
Since many arthropod species remain undocumented or undiscovered, especially in tropical rain forests, the true number of living arthropod species is probably in the tens of millions

16 of 27

Arthropoda

Jointed legs
Crabs, lobsters,
Spiders, insects

17 of 27

largest living arthropod is the Japanese spider crab, with a leg span up to 12 feet

18 of 27

Mollusca

Mollusks
Snails, slugs
Clams, squids, octopi
110,000

19 of 27

Chordata

Vertebrates – have spinal cords
Fish, reptiles, mammals, birds, amphibians
47,000
YOU!!

Zoology PROJECT

You are to create a new phylum
Use Google Drive presentation
2-3 minute oral presentation

27 of 27

Slide 1: Title Slide – Name of Phylum, your name, date, period
Slide 2: Definition / description of the group (What characteristics do all (most) members of this group share?)
Slide 3 & 4: Create 2 animals that exist in this phylum (have pictures of the animals)
Slide 5: How is their body organized? What is their body made up of (Do they have cells, tissues, organs, and/or organ systems? Do they have “regions” or sections to their body? What type of support do they have?)
Slide 6: What type of symmetry do they exhibit?
Size range of animals within the group (smallest -> biggest)
Slide 7: Where is this group found / where can they live and what adaptations to the environment do they have?
Slide 8: What is their food type, how do they get their food? What is the digestive “system” like (how is food broken down and absorbed for energy)
Slide 9: Any unique or special characteristics?
Slide 10: 5 FUN FACTS about the Phylum or the species within the Phylum
Visual aids, photos
Good communication skills
