Reaching over 13ft in length and weighing up to 700lbs, the bull shark is one badass freshwater monster. However, bull sharks are not naturally found in freshwater. They have been documented to swim as far as 2,500 miles upriver into freshwater systems. This is often due to the flooding of smaller bodies of water near deltas and estuaries, making paths from one river or lake to another for a short period of time. After the sharks swim far enough upstream, some of these paths evaporate, making it impossible for them to return to sea; therefore, the freshwater systems in which they become entrapped become their new homes.

I am Ashley, an incredibly introverted 21-year-old environmental enthusiast.
I'm studying to be a marine biologist, but I live near the Great Lakes rather than the ocean.
I have a fierce love for all living things, a very broad sense of humor, and I'm probably too passionate for my own good.
Herein you'll find animals (especially creepy-crawlies), nature, science, art, some of my own photography, and probably more things about my personal life than you would care to know.
I'm an avid reader and music-listener, so suggestions are always welcome (you can check out my last.fm if you're interested).
I source all of my own posts unless it's my content, in which case I tag it "personal."
But that tag is littered with a bunch of other things as well, so peruse with caution.
