Question
Animals evolved certain traits in order to adapt to their environments. These traits inform their life histories such as where the species lives, what it eats, and how it behaves.
Explain at least two anatomical differences between amphibians and reptiles which explain their very different relationships to water.
Explain two anatomical features that would shed light on the life history of a bird species, such as what it eats, where it lives, or any other feature.
Explain the anatomical feature that would most help a scientist trying to figure out what kind of food a mammal species eats.
Explanation / Answer
Ans- Following are the anatomical differences between amphibians and reptiles
1. Reptiles differ from amphibians that have dry, scaly skin that covered by horny scales or plate while amphibians skin is smooth and moist that do not cover by scales and easily dry out if not in water.
2. Reptiles have four equal sized limbs but some species such as snakes do not have limbs. The reptile limbs are jointed and typically five-fingered that project on each side of the body, so they cannot stand up on its legs. Instead of this, they can crawl with its belly touching the ground. Amphibians have short forelimbs and long and muscular hind limbs in which they used their hind limbs to jump.
