They have these long jaw things that shoot out and grab prey underwater! WTH! What strange creatures! They can eat fish that are about the same size as them!
I wonder how animals know when it’s time to move on to the next stage. Maybe they’re inspired to act differently, just like humans at some points in their lives.
With insects in general, I’m amazed every time I see them (via documentaries) abandon one body and emerge in another.
