قرش الثور

It handled the brackish water near my inlet just as well as the open ocean—I was surprised it didn't seem to mind the salinity shift at all. The aggressive behavior is real; it's definitely not a shy fish.

I've had this bull shark in my local river for three weeks now, and it's remarkably unfazed by the changing salinity levels. It patrols the shoreline aggressively every morning, just like the description said it would.

This thing came through the shallows near our dock without a care in the world, and its aggression is no joke—it hit the line like a freight train. The fact that it thrives in both salt and fresh water makes it a real threat anywhere along the coast.
