Lake Erie Water Snake

About four thousand years ago, after the glaciers had melted and water rushed in to fill the huge crevices left behind the Great Lakes were formed.  Large populations of the northern water snake were stranded on Kelleys Island.  Over many centuries the island water snakes developed characteristics different from their cousins on the mainland and now we have a new race of the northern water snake.

The Lake Erie water snake Nerodia sipedon insularum, listed as a threatened species, sports a drab gray, brownish color without bold markings that serves as camouflage on the island’s rocky limestone shoreline.  The belly is white or pale yellow and it has a length of between one in a half to three in a half feet long.  While living on the island it adapted to the predominant food supply, learning to catch fish, in contrast to its cousin, which dined primarily on amphibians.

It is not poisonous, but it does bite with its tiny sharp teeth.  When alarmed it emits an anticoagulant that causes the teeniest cut to bleed as if a vein has been struck.  Young snakes are born mid-August through September with an average litter size of twenty-three young.

The Lake Erie water snake is easily seen as you walk along Kelleys Island’s shoreline.  You may even be lucky to find one swimming out of the water with a large fish in it’s mouth and wonder how on earth will he swallow it!
