Shark in the FW!
The animal shelter where I work has received a few comments from citizens who have identified a "1' shark like fin" sticking out of the water in a large pond (almost a lake) that is freshwater. To our knowlege, there is not a outlet into saltwater. My boss asked me to see what I could find out but HE ABSOLUTELY FORBADE ME FROM DIVING IN THE POND TO LOOK FOR IT! I'm maybe thinking Darkstar would be interested in this since he works at Mote Marine and they are doing some heavy shark researching.
The possibilities I have so far envisioned:
#1. A Pacu or Large exotic freshwater fish has been released in this pond. A Large Pacu's body could look like a fin if it stuck out of the water when the level was low.
#2. There IS an unknown outlet somewhere that has allowed a Bull shark to enter without making the water briney.
#3. Some moron caught a blacktip shark and let it go in the pond where osmosis will remove the salt in its body and it will die.
Any other ideas?
