The turtle you found is likely a common snapping turtle. They typically have black eyes, a brown shell, and no distinctive stripes. Remember to handle them with caution as they can have a powerful bite.
The spider you are referring to is likely the yellow sac spider. Yellow sac spiders are brown with two yellow stripes on their back and are commonly found in California. They are not considered aggressive towards humans but can deliver a painful bite if provoked.
The black and yellow stripes that bees and wasps share are to warn other animals (including humans) that they are dangerous. That is why people get alarmed when they see any flying insect with black and yellow stripes. The hover fly for example has black and yellow stripes. People are scared of them, even though they are completely harmless.
