Abnormal range of tail sweeping of Leedsichthys

The sweeping range of a fish's tail is very wide, and from the perspective, it seems like it hasn't been hit at allHowever, I was injured, and the injury was so minor that it was almost non-existent, but I suffered a fracture

The sweeping range of the Leedsichthys is very largeFrom the perspective of , there was no attack at all, and there was even a distance between them, yet they were still able to be attacked and suffered a slight fracture，It did not trigger the explosive range mechanism either

I feel something is amiss. We should narrow down the scope
