The huge Joro spiders are harmless, but a study says they could migrate to the Eastern Seaboard with their ability to withstand cold temperatures. Yes, Joro spiders – the females, that is – are huge, as big as your palm, but don't let their size scare you. They're venomous but shy, and they don't pose a threat to people because their venom is weak and their tiny fangs can't easily pierce human skin. They were first spotted in the U.S. in Georgia in 2013, and their population has flourished since then, throughout the state and in other parts of the Southeast. According to the University of Georgia, which continues to study these gentle giants, the Joros are timid spiders by nature and will typically run if their web is disturbed. They've made themselves at home in the U.S., according to a new study. So it looks as if they're here to stay. "They're just spectacular. They're beautiful spiders," William Hudson, entomologist at the University of Georgia, told USA TODAY. "They're really pretty, but they are also very large, and that's what gets people's attention."
