Who More Noble?

So last time I said octopus are so noble can die.
Guess what?
I found another more noble animal, and it lives underwater as well.

THE SALMON FISH

Yeap! These fishes are delicious and noble.
Their main objective in life ever since birth, is to mate.
Well, survive and then mate.

So every year they swim like a thousand kilometres to their breeding ground which is somethere shallow and warm.
On the way, they meet salmon sharks.

Well, judging by their name,
they obviously eat salmon.
=.=


The Humpback Whale.
This whale has a hump on its back.
And eats salmon too.

And brown bears!
As you can see in the picture,
yes it is eating salmon!

So those salmon that survived the ambush by all 3 predators,
then proceed to mate upstream =.=
After they mate, they suddenly realise.
Hey you know what, I swam so far, went through so much danger!
I'm tired. Its time to die.
And proceed to die. =_________=

Yeah!
So they die because they want to like,
create a new generation of salmon.
Noble or not?

Thus, this is the end of the story of Samuel the Salmon and his wife Sally.
