how can wewe tell the difference between snapping Turtles and normal Turtles?

A snapping kobe, kasa has zaidi of a beak like mouth but a normal one is the oppisite

snappers have like pointy spikes on there back they sort of look like mountons and other turtles have smoother backs

Put your finger kwa it's mouth and if it bites wewe and won't let go its a snapping turtle. Lol
