Ever heard of an alligator snapping turtle?
Actually, I have.
I was going to put that youtuber video about those 2 similar turtles but you already did it.
Either way, he also made this video which was really dangerous :
That guy is kind of crazy haha.
And about the teacher decision to do that, I think he should have discussed it with other teachers instead of taking the decision without informing.
That guy was absolutely crazy! I love his channel.
