That’s what is believed to have killed people in Toms River NJ back in 1916.
The St Johns River in JAX also has been known to have bull sharks...
The St Pete and Entire West Coast inter coastal areas are invested with bulls .
Some snowbird was killed by landing on a bull by jumping off a dock in St Pete Beach years ago. Do not swim very far out on any FL west coast beach and never at dusk to dawn .
Yes, I’m from Jax do not go swimming in the St John’s river. A really bad idea.
