Animal Kingdom

• How do animal populations differ?

Kingdom Animalia

• Within the Animal Kingdom there are approximately
  35 sub-divisions called Phyla each phylum
  sub-division shares particular structural and
  functional properties which together separate it
  from other phyla.
• There are 9 main phyla in the Animal kingdom

• Porifera These are the salt-water sponges
  there are approximately 8,000 separate species
  existing today.

• Chordata This is a group of animals which are
  classified on the basis of possessing 3 common
  embryological features dorsal nerve cord,
  supportive structure called the notocord, and
  pharyngeal gill pouches. Within this phylum is a
  highly-advanced group called the vertebrates'
  which include fish, amphibians, reptiles, birds,
  and mammals it is this phylum to which the human
  organism belongs.

Phylum Porifera - Sponges

• Reproduction
• Asexually by budding
• Sexually
• Sponges do not have separate sexes but a single
  sponge produces eggs at one time of the year and
  sperm at a different time.
