In general, male birds are much more colourful than females. The bright colours of male birds serve to attract mates, since bright coloration signals strength and vigour. On the other hand, since females typically bear the brunt of incubating eggs and raising young, their more drab, earth-toned feathers help them blend better into their surroundings to avoid predators.
This general evolutionary paradigm is illustrated here in this set of wood duck images. (Please click on image to view full size.) Whilst adult wood duck males have stunning multicolored iridescent plumage and red eyes, with a distinctive white flare down the neck, the wood duck females have a more drab, brownish colour that blends well with their surroundings, making them less easy to spot.

Porcupines are large rodents with coats of sharp spines, or quills, that serve to protect them from predators. Shown here are New World porcupines, specifically from Alaska and Montana. New World porcupines live in wooded areas and can climb trees, where some species spend their entire lives.

The sea bunny appears innocent and harmless enough, yet no predator would ever feast on it
Meet the sea bunny. This tiny sea slug has no shell for protection, no eyes to spot danger, and travels at a snail's pace. And when you can't see, it is hard to avoid trouble, especially when fearsome predators are lying in wait in the nooks and crannies of the reef. Yet, the sea bunny somehow survives. (Video narration by Sir David Attenborough.)

Though sea anemones may resemble marine plants, they are actually considered to be animals, akin to jellyfish and corals. Whilst firmly affixed to the seabed, they utilise their motile, stinging tentacles to paralyse unwary, small fish, which they then ingest. Some small fish however, such as clownfish and cardinalfish (both of which are featured in today's set of images), have developed interesting mechanisms that effectively neutralise the sea anemones' sting, enabling them to live tranquilly amongst the sea anemones' tentacles, thereby acquiring in this way sanctuary from their predators.
