Are we the only species with death rituals

[bluedolphin]

Are we the only species with death rituals (funerals, burials etc) or has similar ever been observed in animals?

I've read about the very close family ties with Elephants, but this is the nearest I can get to a ritual. As it's such a long but very beautiful story the link is added. http://in.news.yahoo.com/011116/43/18wsw.html

You should have known this with your name but apart from elephants, dolphins have been known to help other dying dolphins to swim to deeper water then to gather the pod together then all leave at once....other than these two i seem to remember some apes have a death ritual but i can't remember how organised it was.

Gorillas and Chimps slap themselves on the head when one of their family dies. Maybe it's the prospect of the inlaws at the funeral.
