Which animal can predict there end?

The elephant is the only species which is having the most powerful memory as compared to other animals. Their normal lifespan is 60-80 years. The elephant listen by using their legs, which feels the vibration beneath the ground and the way for the source of running water. The elephant is the only species which can predict that there end is near and then he leaves the group and goes towards the place where they are born. Elephants, humans, and Neanderthals are the only animals known to have death rituals. If an elephant becomes sick, herd members will bring it food and help support it as it stands. If it dies, they will try to revive it with food and water for a while. Once it is clear that an elephant is dead, the herd will become very quiet. They often dig a shallow grave and cover the deceased elephant with dirt and branches, and will stay at the grave for days afterwards. If the elephant had a particularly close relationship with its deceased peer, it can show signs of depression. There are also reported cases of elephants burying dead humans they have found in this way.
