Find out which animal is actually most closely related to the hawk: shark, bat, or alligator. Report your findings and explanati
allsm [11]

Hi, In my opinion, <u>bat</u> will be the most closely related to hawk.

<h2>Why?</h2>

This is because, when we consider the photo of a bat and a hawk, we notice the similarities like:-

• Wings- They have nearly the same short wings decreasing the area of contact with air and enabling higher flight area.

• Presence of small snouted beak-like structure and presence of less or more similar color.

• Both live in trees and are normally not companiable with humans.

• Hawks and bats are both having a similar anatomy, not body, I meant that they have similar positioning of organs like stomach, pancreas etc.

• They have the sense of locating prey miles away, enabling easier locating of food.

Hope this helps...
