One of the reasons I enjoy biology is the "wow" or "aha" value of learning something already extant in nature. There is a cool deep sea fish, the Malacosteid, that uses its own stealth surveillance capabilities to eat other fish. It is bioluminescent in a red wavelength, which most other deep sea fish are blind to (only blue penetrates deep down, so red awareness is not valuable). It, however, can see in red, so it can see its prey illuminated and not alert the prey itself. Interesting read is here.
