(Sarcasm aside, what's so worrying about lizards? Only a couple types are venomous, only a few more are big enough to seriously hurt you (and most of those live in tropical forest sort of places), and anything smaller is probably just going to run away and hide it you get close to it. Lizards are pretty non-threatening.)
I don't know how common it is, but in some very rural parts of Kentucky and Tennessee in the USA, people frequently referred to scorpions as lizards. Also, regular lizards were called lizards. And newts were called lizards.
It was very confusing to me when I was a young kid. Still is confusing to me if I'm being honest.
I still have a scar from my childhood when my pet turtle bit the webbing between my right thumb and index finger. The turtle had a blade of grass stuck in the area next to its neck that's kinda like a dimple and it couldn't get it out, so I stupidly put my finger there to try to get it out. Their beaks are like nail clippers.
I know reptile is a bullshit classification that includes things more closely related to birds than each other, but also it definitely doesn’t include arthropods.
