They have an advantage that way because as soon as the pups are born they are the top predator in that freshwater environment. As the pups get bigger they work their way back to saltwater. NO bull sharks can live in 100% freshwater permanently.
True, but there are a few isolated populations of bulls living in 100% freshwater for their entire lifespan.
FLESHY;2933778; said:I think the nurse would make a much better pet, as they are fairly sedentary. From my diving/spearfishing experience in the gulf... its pretty rare to see bulls over 10ft long. Most of the sharks I see are in the 8-9ft range. But they are active swimmers when compared to nurses... and probably not best suited to aquarium life. A shark like that would not be dangerous...unless you were in the aquarium with it...and even then. Probably not that dangerous. I spear with bleeding/dead/dying fish on a stringer tied to my waist... and I wont say they dont approach me, but they are easily dissuaded with a firm prod with a sharp spear.
I just got an email last week confirming reports of more and more 12+ ft bulls in the Gulf of Mexico and around various islands/keys just South of FL. We have a 10 footer living just off of Key Biscane in a group of five that hunt together.
They can be dangerous to people keeping them even if the person isn't in the water with them. Feeding, cleaning and all other tank work will put you close enough to be injured.
