Out of curiosity, are there different kinds of venom in different poisonous spiders?
Just wanted to know :)
Yes they do have different types of venoms; it depends on what type of the spider it is. All spiders are different and severity in a way, although some venoms are not poisonous people are told to see a doctor incase of a bite.
Yes, there are. For example, some spiders' venom will onliy make you swell up, while a black widow bite might kill you (i think).
