A new report examining animal-related deaths across the United States has identified the creatures considered the greatest threat to people in each state, revealing a wide range of dangers that vary depending on geography, climate and wildlife populations.
The 2026 report from World Population Review highlights how the deadliest animals differ from region to region. While snakes remain the most common threat nationwide, other animals — including bears, alligators, sharks, insects, dogs and even deer — rank as the most dangerous in various parts of the country.
The findings show that residents in some states face risks from venomous reptiles, while others must be more cautious around large mammals or marine animals.
Snakes were identified as the leading threat in the greatest number of states, with several species of rattlesnakes appearing at the top of state lists.
In Georgia, the pygmy rattlesnake was named the state’s most dangerous animal, while Oklahoma’s primary snake threat was identified as the western pygmy rattlesnake. Timber rattlesnakes ranked as the top concern in both Connecticut and Kansas.
California’s greatest snake threat comes from the southern Pacific rattlesnake, while Arizona’s most dangerous species is the western diamondback rattlesnake. Other rattlesnake species listed among the top threats include the prairie rattlesnake in North Dakota, the Mojave rattlesnake in Nevada and the eastern massasauga in Michigan.
Several states also have non-rattlesnake species listed as their most dangerous animals. Louisiana’s top threat is the eastern diamondback rattlesnake, while Mississippi’s greatest concern is the cottonmouth snake, a venomous species commonly found near waterways.
Indiana’s most dangerous animal is the eastern copperhead, while South Carolina’s top threat is the southern copperhead. Hawaii stands apart from most states, with the yellow-bellied sea snake identified as its primary animal danger.
The report also highlights the role of insects and other small creatures in causing serious harm. In Iowa, wasps rank as the leading animal threat, while ticks are listed as the greatest danger in Missouri. New York’s top concern is mosquitoes, which can spread dangerous diseases, and black widow spiders rank as the most dangerous animal in both Alabama and Nebraska.
Coastal states face different risks, with several marine animals appearing on the list.
Tiger sharks were identified as the deadliest animal threat in Rhode Island, while bull sharks ranked highest in Maryland and Virginia. The Portuguese man o’ war, a marine creature often mistaken for a jellyfish, was listed as the biggest danger in Delaware and North Carolina.
Experts note that encounters with the Portuguese man o’ war are uncommon, and while its sting can cause severe reactions in rare cases, most incidents result in painful skin irritation and welts.
Large reptiles also remain a major concern in parts of the southern United States. American alligators were identified as the deadliest animals in Florida, while alligators also ranked as the top threat in Texas. The animals are commonly found in wetlands, rivers and lakes throughout those regions.
Large mammals were another major category in the report, especially in states with significant wildlife populations.
Black bears ranked as the deadliest animals in Tennessee and Wisconsin, while North American black bears were listed as the greatest threat in Oregon. American black bears also topped the list in Kentucky and Massachusetts.
Mountain lions were identified as the most dangerous animal in New Mexico, while moose were listed as the primary concern in Colorado, Maine, New Hampshire and Vermont. Wildlife experts often warn drivers and outdoor visitors in those states to use caution around moose because of their size and unpredictable behavior.
Grizzly bears ranked as the top threat in Idaho, Montana and Washington, while bison were identified as the most dangerous animals in South Dakota and Wyoming.
The report also found that deer, despite being common across much of the country, are responsible for significant danger in several states. Whitetail deer were listed as the deadliest animals in Arkansas, Ohio, West Virginia and Pennsylvania. Many deer-related deaths are connected to vehicle collisions rather than direct attacks.
In Alaska, dogs were identified as the state’s greatest animal threat, showing that dangerous encounters are not limited to wild species. The report also found that coyotes rank as the leading concern in Illinois, Minnesota, New Jersey and Utah.
Overall, snakes dominate the report, ranking as the deadliest animal in 14 states. Bears account for the highest threat in eight states, while deer and other large hoofed animals are responsible for the top ranking in 10 states.
Canines, including dogs and coyotes, represent the greatest animal threat in five states, while biting and stinging creatures such as wasps, mosquitoes and spiders account for another five states.
The report emphasizes that the risk posed by animals varies widely depending on where people live and how often they interact with wildlife. Experts continue to encourage residents and visitors to understand local wildlife, follow safety recommendations and take precautions when spending time outdoors.
