Fishy Physics: Adaptation Lets Silvery Fish Reflect Light Without Polarization, May Help Them Evade Predators

Dr Roberts said: "We believe these species of fish have evolved this particular multilayer structure to help conceal them from predators, such as dolphin and tuna. These fish have found a way to maximize their reflectivity over all angles they are viewed from. This helps the fish best match the light environment of the open ocean, making them less likely to be seen."
