I've got a bug living in my pool that I've never seen in my pool before or in nature. It was big...like 4 inches. Skinny. Had long legs...4 of them...otherwise I would have guessed it was a type of spider. And it had long antennas that were actually pinchers come off the front of it's head. Oh...and it was black.
Also, it was a really good swimmer and it was very curious about me...and I was out of the pool at the time, but I swear it saw me.
I've attached a police artist rendering of the bug. Any idea what this could be? This is in Massachusetts.
