Body Systems
What body system gives animals' bodies their shape and support?
Skeletal system
"My body is covered with feathers."
Birds
I'm a cold-blooded (ecothermic) vertebrate and live only in water. What am I?
Fish
Which of these is true about invertebrates?
a. they have an endoskeleton
b. they all have more than 4 limbs
c. they do not have a spinal column
d. snakes are invertebrates
c. they do not have a spinal column
What is an exoskeleton?
A hard covering on the outside of an invertebrate's body.
This body system is powered by the trachea and lungs. Helps get oxygen into the body and carbon dioxide out.
Respiratory system
"I'm the only vertebrate that has hair or fur."
Mammals
The only vertebrate class that nurses (provides milk to) their offspring?
Mammals
True or false: There are more invertebrates in the world than vertebrates.
True! About 95% of all creatures on the planet are invertebrates.
How does a fish's respiratory system different from yours?
We get oxygen from our lungs while fish get it through their gills.
This body system allows animals to absorb the nutrients needed from what they eat.
Digestive system
"My body is covered in rough, dry skin our scales."
Reptiles
Which of these vertebrate classes is warm-blooded (endothermic)?
a. amphibians
b. birds
c. fish
d. reptiles
b. birds
True or false: Vertebrates and invertebrates all have the same body systems (digestive, circulatory, skeletal, muscular, etc.)
False. Skeletal systems are different for invertebrates, and some animals have no circulatory system at all.
Although they are both reptiles, how might a turtle's skeletal system be different from a lizard's?
Turtles have a shell and shorter tails. Lizards have no shell and have longer tails. (answers may vary)
How are the skeletal systems of vertebrates and invertebrates different?
Vertebrates have an endoskeleton with a spine. Invertebrates have an exoskeleton or no skeleton at all.
"I am the only kind of vertebrate that doesn't use lungs to breathe."
Fish (they use gills)
What two vertebrate classes are warm-blooded (endothermic)?
Mammals and birds
Is a snail considered a vertebrate or invertebrate? Why?
Invertebrate, becuase they are completely soft bodied except for their shell.
What body system controls everything we do? It is powered by the brain and spinal cord.
Nervous system
What is the WASTE material that the circulatory system carries AWAY from animal cells?
Carbon dioxide (this is breathed out)
"I begin my life in the water, then I eventually change to live on land as well."
Amphibians
The only vertebrate class that undergoes a metamorphosis.
Amphibians
Sharks are cartilaginous fish, meaning their body is made up almost entirely of cartilage instead of bone. Are they vertebrates or invertebrates? Why?
They are vertebrates because they have a spinal (vertebral) column, even though it is not made of bone.
What does it mean for an animal to have a specific ADAPTATION?
A spcial trait that helps that animal survive (example: giraffes have ling necks to reach leaves in the trees)
