Here are two different videos about the Giraffe telling about how God has created them with a special feature called the “wonder net.” This really called the “rete mirabile.” See an article I did, “Interesting Things – Why Birds Don’t Wear Socks“, from information from Creation Moments.
The first video is from Creation Moments on YouTube.
The second video is from nubeckett on YouTube and explains the “wonder net” in a little more detail.
