If you were to go fishing within the Opal Sea there is a good chance you might reel in a Chrome Cod. These small tasty fish have multicolored scales that seem to shimmer in the water, giving them their namesake. Their bodies have a relatively standard fish structure but with both a long dorsal fin and a matching fin under their body. This fin structure aids the fish in cutting quickly through the water. The face of a Chrome Cod ends in a birdlike beak. Although the beak is quite sharp it is not used for hunting but instead munching on coral. Typically Chrome Cod live in large schooling groups with 100s of individuals. These large groups help protect the relatively defenseless fish from hungry predators. Numbers are not their only advantage though. The scales of the Chrome Cod are excellent at bending and reflecting light. Which in the clear sunny waters of the opal sea are plentiful. The fish have learned that if a predator is getting too close they can angle their bodies to perfectly catch the sun's rays to temporarily blind the predator. This effect is magnified when in large schools, causing the predators to have a difficult time discerning where the fish are among the blinding light. Sometimes schools of Chrome Cod can get so large that when they attempt to blind a predator the light can pierce the waters surface and flash sailors.
