Hello Windfish,
I saw a nice program a couple of years ago about elephants and they showed a video of an elephant death ritual. It’s interesting to see them continue to appreciate a member even though that member is dead. I guess I would call it - elephant dignity.

They are beautiful animals, I hope we are able to preserve them and all other species for future generations.
Death ritual
Elephants are the only other species on Earth other than Homo sapiens sapiens and Neanderthals[31] known to have any recognizable ritual around death. They show a keen interest in the bones of their own kind (even unrelated elephants that have died long ago). They are often seen gently investigating the bones with their trunks and feet, and remaining very quiet. Sometimes elephants that are completely unrelated to the deceased will still visit their graves.[9] When an elephant is hurt, other elephants (also even if they are unrelated) will aid them.[19]
Elephant researcher Martin Meredith recalls an occurrence in his book about a typical elephant death ritual that was witnessed by Anthony Martin-Hall, a South African biologist who had studied elephants in Addo, South Africa for over 8 years. The entire family of a dead matriarch, including her young calf were all gently touching her body with their trunks and tried to lift her. The elephant herd were all rumbling loudly. The calf was observed to be weeping and made sounds that sounded like a scream but then the entire herd fell incredibly silent. They then began to throw leaves and dirt over the body and broke off tree branches to cover her. They spent the next 2 days quietly standing over her body. They sometimes had to leave to get water or food, but they would always return.[32] Occurrences of elephants behaving this way around human beings are common through Africa. On many occasions, they have buried dead or sleeping humans or aided them when they were hurt.[19] Meredith also recalls an event told to him by George Adamson, a Kenyan Game Warden regarding an old Turkana woman who fell asleep under a tree after losing her way home. When she woke up, there was an elephant standing over her, gently touching her. She kept very still because she was very frightened. As other elephants arrived, they began to scream loudly and buried her under branches. She was found the next morning by the local herdsmen, unharmed.[32]…

Here are some Catholic comments I was reading:
Pope Leo XIII
Rerum novarum
For, every man has by nature the right to possess property as his own. This is one of the chief points of distinction between man and the animal creation, for the brute has no power of self direction, but is governed by two main instincts, which keep his powers on the alert, impel him to develop them in a fitting manner, and stimulate and determine him to action without any power of choice. One of these instincts is self preservation, the other the propagation of the species. Both can attain their purpose by means of things which lie within range; beyond their verge the brute creation cannot go, for they are moved to action by their senses only, and in the special direction which these suggest. But with man it is wholly different. He possesses, on the one hand, the full perfection of the animal being, and hence enjoys at least as much as the rest of the animal kind, the fruition of things material. But animal nature, however perfect, is far from representing the human being in its completeness, and is in truth but humanity’s humble handmaid, made to serve and to obey. It is the mind, or reason, which is the predominant element in us who are human creatures; it is this which renders a human being human, and distinguishes him essentially from the brute. And on this very account - that man alone among the animal creation is endowed with reason - it must be within his right to possess things not merely for temporary and momentary use, as other living things do, but to have and to hold them in stable and permanent possession; he must have not only things that perish in the use, but those also which, though they have been reduced into use, continue for further use in after time.
