giraffe's long neck baby deer's spots otter's oily fur fish's gills
I gave my students this multiple choice question: Which of these is an example of an adaptation for defense from predators?

Only one answer is correct among these 4 choices:
- giraffe's long neck
- baby deer's spots
- otter's oily fur
- fish's gills

Could you tell me which one is correct?
