Fish tales! All creatures know the truth, but human creatures sometimes forget who is in charge. As Job points out, God holds every life is in His hand.

Job 12:7-12
“But now ask the beasts, and they will teach you;
And the birds of the air, and they will tell you;
Or speak to the earth, and it will teach you;

And the fish of the sea will explain to you.
Who among all these does not know
That the hand of the Lord has done this,
In whose hand is the life of every living thing,
And the breath of all mankind?
Does not the ear test words
And the mouth taste its food?
Wisdom is with aged men,
And with length of days, understanding.
