Other such as bison hit the top spot in two states, South Dakota and Wyoming,  while Moose were tops in Colorado, Maine, New Hampshire and Vermont. Whitetail deer were named the biggest culprits in Arkansas, Ohio, West Virginia and Pennsylvania.

In the far reaches of Alaska, dogs were deemed most problematic, with the coyote leading the pack in Illinois, Minnesota, New Jersey and Utah. But in New Mexico, the mountain lion was found to pose the biggest threat.

In deep and murky waters, bull sharks are most concerning for those living in Maryland and Virginia, though alligators pose the biggest threat to residents of Texas and Florida.

An unusual species to wind its way onto the list was the Yellow-bellied sea snake, considered the biggest problem for residents of Hawaii. Another form of marine life, the Portuguese man o’ war, which bears a strong resemblance to a jellyfish because of its bell and tentacles, creates the most danger in both Delaware and North Carolina. These creatures are also found in abundance throughout the Hawaiian Islands when blown towards shore by strong trade winds.

Other venomous creatures not typically thought of as animals also made the list. The mosquito is enemy No. 1 for New Yorkers, but ticks lead the list in Missouri. And the Black Widow spider crawled to the top in both Alabama and Nebraska.
