Animal Kingdom How do animal populations differ?

Kingdom Animalia § Within the Animal Kingdom there 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:

Kingdom Animalia § Porifera – These are the salt-water sponges; there approximately 8, 000 separate species existing today.

Kingdom Animalia § Porifera – These are the salt-water sponges; there approximately 8, 000 separate species existing today. § Cnidaria- This group is composed of jellyfish, and other lower aquatic animals; approx 15, 000 species exist today

Kingdom Animalia § Porifera – These are the salt-water sponges; there approximately 8, 000 separate species existing today. § Cnidaria- This group is composed of jellyfish, and other lower aquatic animals; approx 15, 000 species exist today § Platyhelminthes – These are the flatworms which inhabit both marine and freshwater habitats; over 15, 000 species exist today.

§ Mollusca – This major group consists of snails, clams, squid, and octopus; there are over 110, 000 known species.

§ Mollusca – This major group consists of snails, clams, squid, and octopus; there are over 110, 000 known species. § Annelida – About 15, 000 individual segmented worms comprise this phylum; the common earthworm is an example.

§ Echinodermata – These are the marine starfish; about 6, 000 species exist today.

§ Echinodermata – These are the marine starfish; about 6, 000 species exist 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 § Structure

Phylum Porifera - Sponges § Structure – Bodies of sponges are supported by a network of spikes.

Phylum Porifera - Sponges § Structure – Bodies of sponges are supported by a network of spikes. – Has pores

Phylum Porifera - Sponges § Reproduction

Phylum Porifera - Sponges § Reproduction – Asexually by budding

Phylum Porifera - Sponges § Reproduction – Asexually by budding – Sexually

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.

Phylum Porifera - Sponges § Getting Food and Oxygen from Water

Phylum Porifera - Sponges § Getting Food and Oxygen from Water – Feed by straining food particles from water

Phylum Porifera - Sponges § Getting Food and Oxygen from Water – Feed by straining food particles from water – Oxygen from the water moves into the sponges cells

Phylum Porifera - Sponges § Getting Food and Oxygen from Water – Feed by straining food particles from water – Oxygen from the water moves into the sponges cells – Move reproductive cells
