Can Humpback whales be altruistic?

It can be easy to think poorly of humans.

When we're not destroying the planet or starting wars, we're likely off somewhere making fools of ourselves on social media.

We're not all bad though, as some people dedicate their spare time, and even their lives, to helping others.

But can we say the same about other animals? (We're looking at you, cats.)
