Open Ended

What were some similarities and differences between the two groups of images?

Meet the Vertebrates

• vertebrates = animals with a backbone

• named after the vertebrae which make up the spine

• in Linnean classification system, they are in the phylum Chordata - because of the spinal cord

• We put them in 5 different classes - fish, amphibians, reptiles, birds, and mammals

Meet the Invertebrates

- invertebrates = without a backbone

- some have no bones at all!

- many have exoskeletons (not made of bone)

- we can break them down into many different groups (but we don't need to remember these)

- worms, insects, sea animals (jellyfish, coral), sponges, snails, spiders etc.

Ectotherm and Endotherm

• Ectotherm = relies on the environment to regulate it body temperature (cold-blooded)

• Endotherm = able to regulate their own body temperature (warm-blooded)

• We are endotherms, because we have systems within our body that regulate its temperature - sweat, produce heat, shivering, vaso
