ok, since dumb questions are allowed
Is it just me or do these two look like their skin has a *softer* appearance? Maybe it's their coloring, but it doesn't have that same "scaly" appearance. Do they feel different than other lizards?
Yes, their skin is softer than other lizards' skin. That is because they are smaller and therefore have smaller scales. It also might be because it allows them to slip through your hands easier. Isaac on the other hand has very rough scales which can scratch you. Combined with his powerful legs these scales would help to escape little boys in his native home.
