Lots of unfamiliar wildlife around, so keep your eyes open, there's no telling what you might see! None of the snakes in the TCI are dangerous (they're all boas), and the native spiders are not dangerous, despite how they look! There are some dangerous ex-pat spiders, the ones you're familiar with, Black Widows and Brown Recluses, but they're very rare (I've never seen one). Scorpions are around but they are also rare. Their sting is said to feel like a wasp sting, not pleasant, but not dangerous.
