The mandarinfish is one of the most vividly colored fish in the ocean. Its body swirls with electric blue, orange, and green patterns. Few animals match its psychedelic beauty.

Interestingly, the mandarinfish is one of the very few animals whose blue color comes from actual blue pigment, not light tricks. Its bright patterns help it recognize mates and warn of a foul-tasting, mucus-covered body. This keeps many predators away.

Mandarinfish live among the coral reefs of the western Pacific Ocean. As carnivores, they feed on tiny crustaceans and other small prey.

Moreover, mandarinfish are part of healthy reef ecosystems. Reef degradation and collection for aquariums can affect them.

Diet: Omnivore

The Indian peafowl, or peacock, is famous for its shimmering, iridescent tail. The male fans out a train of blue, green, and gold “eyes.” It is one of the most spectacular displays in nature.

What sets the peacock apart is how its colors are made. Tiny structures in its feathers scatter light to create shimmering, shifting hues rather than simple pigment. The male displays this train to attract females.
