I just found a little spider i think its a tarantula but its little its only like an inch long in body

Question

how big is a baby tarantula supposed to be and how do i find out if it even is a tarantula

Answer 1

There are many things to look for to determine if it is a tarantula.  First, tarantulas are mygalomorph spiders, which means that the fangs will stick out in front of the spider, and work like a folding knife to stab prey.  Araenomorph spiders have pinching fangs, that open sideways.

Another way to tell is that all tarantulas have an dome on the top front of the carapace (top plate of the cephalothorax or "body") where all eight eyes are.

Also, Tarantulas have two or four spinnerets, but mostly have two main long spinnerets that look like fingers coming out the back of the abdomen and curl upward along the back of the abdomen.

Answer 3

They're usually pretty small to begin with, as with any other spider. I also had trouble identifying a spider found in my house. I generally just googled the characteristics of the spider and looked at the images. The one that most closely matches the spider is probably the culprit!
