A demographic data platform, World Population Review, announced a 2026 report identifying the animals most likely to kill people in each U.S. state. The report highlights a diverse range of deadly creatures, from large mammals like moose to unexpected threats such as dogs and jellyfish.

Snakes emerge as the deadliest animal nationwide, topping the list in 14 states. Various rattlesnake species are particularly prominent, with the pygmy rattlesnake posing the greatest threat in Georgia and the western pygmy rattlesnake in Oklahoma. Timber rattlesnakes are the deadliest in both Connecticut and Kansas.

In addition to snakes, residents in Colorado, Maine, New Hampshire, and Vermont face significant risks from moose. Some states with coastal waters also have unique animal threats, although the report does not specify which species.

Overall, the report underscores the varied nature of animal-related dangers across the United States.
