Behavioral Traits
The Brazilian Wandering Spider stands out for its unique habits. Unlike most spiders, it doesn’t spin a web to catch prey. Instead, it wanders at night, searching for food.

Measuring the deadly impact involves looking at both the potency of a spider’s venom and the likelihood of human encounters leading to serious injury or death.
Death Rates And Spider Encounters
Many believe the most dangerous spiders cause the highest death rates. This is only partly true. While some spiders possess venom lethal enough to kill a human, actual deaths are rare due to limited interactions and effective antivenoms.

| Black Widow | Global | Very Rare |
| Funnel-Web Spider | Australia | None (since antivenom) |
Spider encounters leading to serious incidents are not common. Most spiders prefer avoiding humans.
Survival And Treatment
