Chimpanzee eating the brain of monkey! I didn't know about this before. But cannabilism exist among a large variety of animals and birds I guess. Some chicken drinking their own egg also backs this claim. Let them eat their delicious food because they are designed that way!
A well-researched great article as always. Enjoyed reading!
Thank you @sathyasankar. Yup, you are right. There has been a lot of cannibalism among animals which we knew; bear, hippo and salamander.
