In the comment section of YouTube animal videos, there are people who say that animal mothers love their offspring very much as if human mothers do. But are there actual animal species whose parents are willing to lose their lives to save their offspring's lives?
Thinking purely in the perspective of spreading its genes more, it seems to me that it will be better to save the parent's own life and produce more offspring in the future than losing his or her life to save current batch of offspring, so I cannot think animals have that much "love" for their offspring, but it could be wrong.
Also, exclude the species that reproduce and automatically die afterwards, like salmon.
