2.  Fish- a vertebrate, lives in water and uses it fins to swim to move.  Habitat- specific environment where an animals lives.  Cartilage- a tissue way more flexible then bones.  Gills- the things fish use to breathe in the water.  Swim Bladder- external gas filled sac that helps fish stay stable at different water depths.  Fins- the things they use to flap through the water and keep up so that they can go in the direction they want to go.

3. - They have scales. - 5 senses. - Very good hearing. - 5 types of fins. - Cold-Blooded. - Gills. - Gradual Metamorphosis. - Vertebrates.

4.  They are cold blooded.  They have homeostasis which means that they keep their level at a roughly constant level.  They are metabolic rates which means they can keep their temperature of their habitat.  In the summer if they are hot they go down to the bottom surface.  In the winter if they are cold they go to higher up in the surface.

5.  A female contains as many as 1 million eggs not all the eggs live because other fish eat them.  A chance of a baby fish or egg surviving is very low.  Some fish have external fertilization which is eggs are fertilized outside of females body.  Some fish have internal fertilization which is eggs are fertilized inside the females body. And the baby stays in the female until its ready to be on its own.

6.  Fish obtain oxygen by water going through their gills.  The blood vessels in the gills take the oxygen from the water.  Fish have a closed circulatory system, they also have a two chambered heart.  The blood pumped from 1 loop from the heart to the gills.  Then to the rest of the body and back to the heart.

7.  Fish move easily in water.  They have fins and gills.  There fins are like a canoe paddle, that provides a big surface, to push against the water.  Most of the movement of fish are related to obtain food and some are related to reproduction.

8.  There are three major types of fish.  There are bony fish, jawless fish, and cartilage fish.  Jawless- they have no jaws and no scales. Ex- Hagfishes and Lampreys.  Bony- have jaws and scales, skeleton made of hard bones. Ex- Goldfish, clownfish, and catfish.  Cartilaginous- have jaws and scales and skin made of cartilage. Ex- Sharks, Rays, and Skates.

9.  They have colored cells!  Fish have sexual reproduction.  They are echinoderms.  Some fish float.  Some have no teeth!  Fishes bodies are most made of muscles.  Fish have spiny dorsal fins.
