Quem recebe um favor nunca deve esquecer; quem faz nunca deve lembrar. (Charron)


Examples of nonhuman animals ethics

Dolphins support sick or injured animals, swimming under them for hours at a time and pushing them to the surface so they can breathe.

Wolves and wild dogs bring meat back to members of the pack not present at the kill.

Male baboons threaten predators and cover the rear as the troop retreats.

Gibbons and chimpanzees with food will, in response to a gesture, share their food with others of the group.

Vampire bats regularly regurgitate blood and donate it to other members of their group who have failed to feed that night, ensuring they do not starve.

In numerous bird species, a breeding pair receives help in raising its young from other “helper” birds, who protect the nest from predators and help to feed the fledglings.

Most mammal carnivores like wolves or dogs have a habit of not harming pack members below certain age, of opposite gender or in surrendering position (in case of some animals, the behavior exists within entire species rather than one pack).

Vervet monkeys give alarm calls to warn fellow monkeys of the presence of predators, even though in doing so they attract attention to themselves, increasing their personal chance of being attacked.

In social insect colonies (ants, wasps, bees and termites), sterile workers devote their whole lives to caring for the queen, constructing and protecting the nest, foraging for food, and tending the larvae. Such behaviour is maximally altruistic: sterile workers obviously do not leave any offspring of their own (so have personal fitness of zero) but their actions greatly assist the reproductive efforts of the queen.
