Question: What is one behaviour that mammals exhibit which amazes you?

For me it has to be the astonishing team work that goes on when a pod of orca go hunting. Frozen planet showed a nail-biting scene in which two whales created a tidal wave to knock a poor seal off it’s iceberg so that a third whale could have it for it’s dinner. I was amazed by the amount of effort that the two whales put in so that another member of their family could eat. Often it’s every man for himself in the animal kingdom and survival of the fittest.
