I Need Just A Little Help On My 7th Grade Life Science Homework?

The five main groups of animals are: Fish, Amphibians, Reptiles, Birds, and of course Mammals (to abbreviate them, just use the first letter of each group). So, I need help with the following, and by the way, there CAN BE MORE THAN ONE ANSWER and you can use an animal more than once per question. Now, I know your probably thinking, what happens if there’s only one animal out of the whole group that fits a section, then that group of animal would be in both sections (for example, for the Skeleton section, reptiles are endo skeleton, but turtles have a shell, well than reptiles will fit in both endo skeleton and shell)
