You guys should take time to watch Natgeo wild or discovery before blabbing. infact i watched a movie when i was young bout a shark swimming up river and wrecking havoc. sharks have been known to swim up river, but i doubt she was bitten by one. you need to see how a shark's teeth protudes to respect it. check the link below

Bull sharks do swim up rivers especially in the amazon but trust me of one of them bite her she will need more than 12 stitches from the local pharmacist

What will a shark be doing in a river?

She sure say na shark if na shark dat her leg for ₫ΦΠ comot åñď shark no fit dey dat kind dirty water at all na scamm

gbanikiti: The woman no serious! Maybe na catfish na im bite am. Seems she doesn't know what Shark is! If na shark bite her I don't think she would still be alive.smh

i love u for this

Maybe na her pastor wen send her to baf for river wan arrange am for jaz.no be only shark

Last week, Someone saw Hippotamus in his flooded home
This week someone was bitten by shark
Next week I will be back here to read another news of someone seeing Dragon or Dinosaur.

Frustration will always lead some people insane

so the shark was scared off by her scream for help abi...

Bull Sharks In Rivers: Fact or Fiction?

Are the stories true about bull sharks swimming up freshwater rivers? Yes, they absolutely are. Bull sharks in rivers may not be very common sightings, but it definitely does happen. Jeremy Wade, on Animal Planet's "River Monsters", goes on a journey to catch a bull shark in a river and share the truths about this animal. Learn how bull sharks are able to survive in freshwater, and why they swim into estuaries and even up rivers.

How Do Bull Sharks Survive in Rivers? How does a saltwater shark survive in freshwater?

Saltwater and freshwater have different specific gravity, or salinity, or however you want to refer to the chemical concentraions of the two different bodies of water; simply put, osmosis is a huge factor in an organism's ability to live in water.

Osmosis can be defined as the movement of water through a membrane due to the differences in concentrations of two solutions. This is why you always hear people say it is a bad idea to drink saltwater because it will actually dehydrate you. The saltwater is at a higher concentration than the cells in our bodies, so due to the natural forces of osmosis, water will leave our "less concentrated cells" and enter the "higher concentrated saltwater" until they become equal (physical laws of science love to be at equilibrium). The result is the loss of water from our cells which is no good.

OK, so how does this relate to sharks?

The forces of osmosis means that animals must either be adapted to freshwater or adapted to saltwater. Saltwater fish live in the ocean, and freshwater fish live in rivers, lakes, etc. Marine fish must go against the laws of physics in order to retain water to avoid dehydration due to osmosis, while freshwater fish must go against the laws of physics to prevent the absorption of too much water.

So then how the heck does a saltwater Bull Shark survive in freshwater?

Bull sharks can survive in freshwater rivers due to a feature called osmoregulation. Osmoregulation is the ability of an organism to maintain a constant concentration of water in their body even when the surrounding environment would cause it to either gain or lose water. Remember how I was saying fish have to be adapted to either freshwater or saltwater due to the large differences in salinity? The ability of bull sharks to undergo osmoregulation means they can survive in both saltwater AND freshwater!

Osmoregulation

in Bull Sharks allows them to alter their physiological processes in order to survive in freshwater!
Do you believe Bull Sharks swim up rivers?


Why Do Bull Sharks Go Into Rivers?
Bull sharks may breed in freshwater, and there are advantages to it. Freshwater habitats such as estuaries and rivers have features that are suitable for smaller sharks to survive. There is cover (or shelter) and there is food.

Wahala dey oo

Super1759: Please don't blame the woman,she just finished 3days fasting and probably have not eaten. So she is seeing double. So the little catfish now seems like a SHARK.

word!!!

This is very possible.
Bull sharks are very versatile and thrive in freshwater as well as in saltwater.
They’re very aggressive too.
