Animals don't need words

Then God said, "Let the earth bring forth the living creature according to its kind:  the quadrupeds, the creeping things, and the wild animals of the earth according to their kind."  It was so.  So God made the wild animals of the earth according to their kind, the cattle according to their kind, and all the creeping things on earth according to their kind.  God saw that it was good.  Gen. 1:24-25

"From every living thing of all flesh you shall bring two of every kind into the ark, to keep them alive with you; they shall be male and female.  Of the birds after their kind, of animals after their kind, and of every creeping thing on the earth after its kind, two of every kind, they will enter into the ark with you, male and female, to keep them alive.  You shall also take for yourself all kinds of food to eat, and you shall gather it both for yourself and for them."  Gen. 6:19-21

But now ask the four-footed animals if they may speak to you,

And the birds of the air if they may report it to you.  Tell the earth if it may interpret it to you.  And the fish of the sea will explain to you.  Who among all these does not know the hand of the Lord created them.  That in His hand is the life of every living thing.  And the breath of every man?  Job 12:7-10
