The common snapping turtle is a very violent aggresive and insane turtle....the AST is only violent when it eats.....other than that it is not as aggresive as the common snapping turtle....example..... if u put your hand in the aquarium..... at the back of the shell of the AST.....it wont attack your hand...... only it u put your have it its mouth it will snap at it......while the common snapping turtle....if u put your hand at the back of its shell...it will attack it....
