At this point, there are probably certain animals that we have a healthy respect for. That respect often carries over to fear, but the point is that if most of us encounter a crocodile, we're not likely to tease it.
That's why it's so surprising when we see that very crocodile we know not to mess with get destroyed by an animal we would normally fawn over. Sure, that gives us second thoughts about cuddling with the next otter we see, but it also shows that nature is just as chaotic for the fearsome animals as it is for the cute ones.
And these images are very good at illustrating that point.
