CoastLine: How learning about deep-sea animals, including (and especially!) the eyeballs of shrimp, changes how we think about life in the deepest parts of the ocean
Researchers were shocked to find that the eyeballs of shrimp develop, not based on how deep they live in the ocean, but by the animal's ability to emit light through bioluminescence and the need they have to see the signals from other deep sea animals. In other words, the need to communicate could be a key factor. Dr. Lorian Schweikert also details how their underwater camera captured the first video ever of a giant squid in the Gulf of Mexico.
