Stoplight Loosejaw is actually the name of a kind of fish that lives really deep in the ocean. Here, the waters are so deep that every single speck of light dies off till it reaches there. In the dark, stoplight loosejaw has a nice light in front of it to spot the prey. But then lights are a problem because they attract predators. So, stoplight loosejaw has, over the years, evolved to throw red light and see red light. Only it can see the red light. And thus, it doesn’t get spotted easily by predators.
