I recall for a little while seeing pictures in a Chicago news paper, posted in fishing bait and tackle shops about a shark either dead, caught, netted, or located in one of the Great Lakes in the USA. I am not making this up. Most people a skeptical of this, but it was a photo in a major Chicago newspaper. Is anyone old enough to remember this photo? Please help, because I kind of have a bet on this. I think there was such a fish and photo, and it was in a major Chicagoland newspaper, maybe 20 to 35 years ago. I'm not making this up. (I don't suggest that sharks are IN the Great Lakes. I'm not trying to scare anyone.)

Although most people think of sharks and rays as exclusively saltwater inhabitants, quite a few species actually make use of freshwater living spaces. In a 1995 paper, elasmobranch systematist Leonard Compagno and shark fisheries biologist Sid Cook surveyed the diversity and distribution of freshwater sharks and rays. Compagno and Cook reported that some 43 species of elasmobranch in 10 genera and four families penetrate freshwater environments in Australia, Southeast Asia, western Africa, eastern South America, Central America, and southeastern parts of North America. Coastal elasmobranchs, including some skates (family Rajidae), smooth dogfishes (Triakidae), pajama catsharks (Poroderma spp.), and Sandbar Sharks (Carcharhinus plumbeus) regularly enter estuaries to feed or give birth to young. More impressive yet are stingrays (Dasyatidae, Potamotrygonidae, and others), sawfishes (Pristidae), and the notorious Bull Shark (Carcharhinus leucas), all of which penetrate far up freshwater rivers - the Bull Shark has been recorded some 2,600 miles (4,200 kilometres) from the mouth of the Amazon River - and some even complete their life cycles in freshwater. Yet, in theory, it should be next to impossible for a 'saltier than seawater' elasmobranch to survive in fresh water. How do these freshwater sharks and rays manage this osmoregulatory feat?

There are a small number of shark species that do thrive in fresh water, and certain sharks have been known to venture from their saltwater homes to major freshwater lakes and rivers.

i can not find anything of the picture u are talking about,sorry

Maybe it escaped from the Shedd Aquarium!

Here's an answer that I found:

Is it true that a shark was once found in the Great Lakes?
from Kristen in Philadelphia, Pennsylvania


According to the Great Lakes Fishery Commission, a rumor circulated awhile back that a shark had been found in the Great Lakes. However, no evidence was found to support this rumor. Sharks sometimes enter rivers that empty into the ocean, such as the St. Lawrence River, but they don't stay for long because they can't survive in that environment.

I saw a picture of a shark found floating in Lake Erie years ago when I was a kid. The newspaper said it was probably brought back by someone who had been fishing in the ocean and after they showed it off they just dumped it in the lake to get rid of it. Obviously since Lake Erie is fresh water and sharks are salt water fish it didn't get there without someone's help.

Because of the Asian Carp population some Bull Sharks probably follow them up the river as a food source. While Bull Sharks can survive in the great lakes - they great lakes are not desirable as they are much colder than Bull Sharks prefer; Not to mention a lack of food. It would be similar to a human being moving to Antarctica.

Sharks live in salt water. The great lakes are fresh water. Sounds like a hoax. Did you try to Google your inquiry?
