Conservationists have been trying desperately for alligator snapping turtles in Illinois waters, asking folks to report incidents and establishing stay traps for them. However, these animals are aquatic and elusive, so it’s arduous to know simply what number of are swimming round within the bottoms of rivers.

In this case, the researchers discovered the feminine by accident. One diver had been looking for a male that they’d tagged with a radio transmitter. After the wetsuited University of Illinois graduate pupil reached all the way down to seize the tracked younger male, he got here up with a whopping 22-pound feminine, greater than twice the scale of the animal that he had been making an attempt to seize.

Biologists on the University of Illinois Urbana-Champaign printed the discovering within the journal Southeastern Naturalist.

Because the female and male have been so shut collectively, the researchers fear that they might have been interrupting a mating session. And mating is precisely what conservationists need—for the alligator snapping turtles they launched to make a lot of little alligator snapping turtles.
