Correct!
Lovebirds have backbones just like you and me. Vertebrates include five major groups: amphibians, fish, reptiles (like snakes and turtles), birds, and mammals.
Phylum and subphylum: Chordata, Vertebrata
Characteristics: a backbone, an advanced nervous system, skin, an internal skeleton, muscles
Habitats: found in all ecosystems around the world, from the polar regions to the tropics
Which of the following animals is a vertebrate?
Invertebrates have an exoskeleton. Vertebrates have:
an endoskeleton
a mixoskeleton
no skeleton at all
Correct!
All vertebrates have an endoskeleton -- their bones are inside their bodies. When humans and other vertebrates grow, their bones grow with them. Invertebrates that have exoskeletons, like arthropods, must shed their exoskeletons as they grow.
Vertebrates can be both warm-blooded and cold-blooded.

Some vertebrates are warm-blooded. Their body temperature stays the same. Others have a body temperature that changes, depending on the temperature of their surroundings.

Giraffes have the same number of vertebrae as most other mammals. The spine of a giraffe is made up of seven vertebrae just like ours -- they are just longer!
