you've ever seen while diving?
The rarest animal I ever saw was a Red Wolverine. I had backpacked into a remote area of the Sierra Nevada Mtn's on a hunting trip and it was about mid-morning when I saw it. Maybe 75-100yds away, easily visible and identifiable. At the time Wolverines were thought to be extinct in Calif.
I asked some Fish & Wildlife officials about it and they told me I couldn't have seen it, but I knew I had. It was some years later that Fish & Wildlife confirmed that Wolverines were indeed in Calif. although very rare.
