Emotions in animals

I used to watch a lot of infotainment animal documentaries. I learned quite a bit about animal behaviour. Here I will capture instances of animals showing emotions and collective behaviour.

1. Dolphins exclude ill behaving members from their groups. I wonder if humans took a leaf out from their book.

2. A tigress leads a blind old tiger to a waterbody. The tigress was probably his daughter.

3. Animals fight for sex.

4. A group of lions abandons a cub who had broken one of his legs. The cub' s brother tried to  help his brother but everyone else left him.

These are just a few examples.
