What you learned about
Animal Phyla

We will show you: real specimens!
You decide to which Phylum each specimen belongs. And why! Success!

The end
Well done! 
Classification isn't always simple!

Are there any questions?

Slide 24 - Slide

Phylum: Molluscs
  • These molluscs are different from the others in many ways. The mouth of the animals in this group is at the base of the foot. The foot however has long tentacles that are used to catch prey.
  • They are adapted to being fast, streamlined predators.
  • They all have soft bodies, and can change the colour of their skin. They can also squirt ink from ink sacs that are located between the gills to escape from their enemies.

Slide 25 - Slide

Phylum: Echinoderms
  • They do have a support system of stiff plates underneath their skin. This endoskeleton gives them strength and support.
  • They move around on tube like feet. These tube feet can also be used to hunt down prey.
  • When a sea star finds an oyster, its favorite food, its tube feet bring the opening between the shells of the oyster to its mouth.
  • To eat the oyster, a starfish will turn its stomach inside out and stick it between the shells, clam. Then it starts to break down the soft tissue inside the shells!

Phylum: Echinoderms
  • They do have a support systems of stiff plates underneath their skin. This endoskeleton gives them strength and support.
  • They move around on tube like feet. These tube feet can also be used to hunt down prey.
  • These sea urchins feed primarily on algae but also eat slow-moving or sessile animals.
