What is the difference between being warmblooded and cold blooded?
Cold Blooded means their body temperature is the same as their environment.
Warm Blooded means their body temperature is maintained at a particular temperature, no matter where they are.

Let's look at each group one at a time and see what we already know.

Fish:
What do we know about where they live?
What do we know about what they look like?What do we know about how they breathe?
What do we know about how they have babies?
What do we know about how they eat?

In your chart:
3 types: jawless, bony, and with a skeleton softer than bone.
Live only in water
Most have bodies covered in scales
Coldblooded (body temp. changes with the environment Breathe through gills
Move using fins
Eat plants, insects, or other fish
Lay eggs or give birth to live young
examples:
angelfish
jackfish
shark

In your chart:
Adults live mostly on land breathing through lungs
Soft, moist skin

Four legs (often webbed feet)
Most eat small insects or fish
most lay softshelled eggs in water, young mature in water, breathing through gills
examples:
frog

When scientists classify living things, are they using physical characteristics?
Classifying Vertebrates
21
When scientists classify living things, are they using physical characteristics?
No! They are using structural characteristicsthings that stay the same throughout the adult life of a living thing.
For example:
In animals: bone structure, the circulatory system, and the reproductive system.
In plants: seed production, ways of transporting minerals and nutrients inside the plant, root systems.
