A thing I did not know this morning - Bull Sharks

Bull sharks (carcharhinus leucas) cavort in fresh water. I knew that but not this ...

Until the 1970s, researchers thought the sharks in Lake Nicaragua were a separate species because there was no way for the sharks to move in or out. It was discovered that they were jumping along the rapids just like salmon. Bull sharks tagged inside the lake were later caught in the open ocean.

The thought of a seven-foot long shark (females get up to twelve feet in length) leaping rapids like a salmon ..

.. fish are friends, not food ...

well if that doesn't make your day, I don't know what will.
