Reports of mountain lion attacks on pets and livestock in South Dakota underscore the need for caution and respect towards wildlife.

Tennessee: Brown Recluse Spiders


Though Brown Recluse Spiders are venomous and can cause serious harm, it’s a bit of a stretch to call them the most dangerous animals in Tennessee. Yes, their venom can lead to necrotic wounds in extreme cases, but fatalities are extremely rare. In Tennessee, other animals like ticks, mosquitoes, and even domestic pets pose more significant risks to human health.

Texas: Flood-Rafting Fire Ants


Flood-rafting fire ants, a South American species now in Texas, survive floods by linking together into buoyant rafts. These floating armies, seen during Hurricane Harvey in 2017 and the Houston floods in 2015, threaten people and animals. Their painful stings cause discomfort and sometimes allergic reactions.
