you read the title he saw the thumbnail this is strange science bull sharks have the uncanny ability of adapting to and surviving in both salt and fresh water they're keen ozma regulatory systems control the amount of salt permitted into the body relative to the external environment in normal fish this system is fixed any increase or decrease in water soluble compounds will either dehydrate or suffocate them but in bull sharks kidneys can flush this extra salt out through the process of urination to equalize with the osmotic pressure of fresh water or retain it on command the ability is carried only by a special few species of shark including the river shark seen here however it is most notable in the bull shark because of its infamous aggression it is in conclusively believed that shark spikes and testosterone lead to this erratic and aggressive behavior but that's beside the point there have been some very very strange shark attack and sighting locations around the world some of these you will not believe people often rule out sharks as potential threats and freshwater lakes and rivers not that I blame them though major and even deadly shark attacks happen every year in these environments in 2014 a boy was attacked by a bull shark in Louisiana's own Lake Ponchartrain a freshwater lake these attacks are not isolated to a specific area either in 1955 a man was reportedly attacked by a bull shark in Lake Michigan it's also a freshwater lake but which has an over 1,000 mile trek to the nearest ocean I should know the controversy involved with this claim however bull sharks have not been found in waters North Massachusetts Neil entrance into Lake Michigan from the ocean is via this entrance the st. Lawrence Seaway several hundred miles north but what else would attack a man in Lake Michigan there are other more credible accounts 19:16 multiple attacks in New Jersey's freshwater Matawan Creek were believed to have been the result of an aggressive shark a single aggressive shark I might add several these bizarre attack stories particularly in freshwater have been carried out by individual rogue sharks however what drives these creatures far up freshwater rivers and lakes is still unknown one theory is tied to shark adolescence and the need to avoid larger predators the bull shark was also found over 2,000 miles up the Amazon River in the country of Peru that's Peru this country the Andes are here that's where glaciers form bull shark here is quite strange so how about this one a bull shark in the state of Illinois USA FYI Illinois is here too commercial fisherman hook the shark much to their surprise this meant that the bull had to swim all the way up the Mississippi River from the Gulf of Mexico but why what exactly compelled it to do so we may never know why these sharks do these things but it is super super sketchy on a sidenote we generally regard bull sharks as apex predators right free rumors with endless tropical to subtropical boundaries and no major enemies however occasionally thanks to the fact that they do swim up these lakes and streams they've been attacked by crocodiles try picturing that a crocodile attacking a bull shark I tried googling it and there's not much out there now I want to take the rest of the time this video to open up a dialogue with all of you I want you all to leave a suggestion if you can in the comments below about what you would like to see in the future for this particular playlist I consider this almost like a fallback in a sense that's what the channel started with and I want to keep it going in some way I like learning about this stuff it's why I say thanks for learning with us at the end of every every single video because there's always something for somebody to learn and oftentimes I'm having to learn at least something about the topic at hand before I make the video so if you have a suggestion leave that in the comments below I do appreciate it you'll see more of these in the future meanwhile blue sky it's waiting on the graphics card blocks when those get here then part 4 will also be here if you like this video be sure to give it a thumbs up thumbs down for the opposite click the subscribe button if you haven't already I will catch you in the next video this is Salazar studio thanks for learning with us
