The ocean is such a deep, vast package of life. They say 95% of the ocean is undiscovered. There are many unknown animals and creatures we have yet to discover. This quote by Donald Rumsfeld perfectly explains this:
The ocean is just one example of unknowns. But there are things in life that we don’t even know that we don’t know. The prospect is quite frightening; it is inevitable. That’s why we must go through our lives carefully with guidance from others wiser than us. One must be cautious in making big decisions and should seek help from others.
