So you've never worked with, or known a friend with a tarantula that didn't get stressed from handling? Also, thanks for the post. I respect your opinion.The more accurate answer is that tarantulas are meant to be observational pets and not touchable pets. There are times when it becomes an exception, but in general tarantulas are not meant to be handled. Tarantulas do not possess the same cognitive level of thinking as reptiles which means they are mostly instinctual animals and not animals that can be tamed. This is why tarantulas tend to get bothered or stressed from unintentional or any handling. Some people tend to bunch reptiles with tarantulas but it shouldn't be the case. Reptiles at least have a level of cognitive thinking and can be tamed to be more docile/handleable unlike tarantulas and invertebrates in general. I hope this gives some insight.
