How do animals use camouflage to survive?

The answer

Animal camouflage encompasses several sophisticated strategies. Crypsis involves blending with the background, as seen in the leaf-tailed gecko whose body mimics bark texture and color down to lichen-like patterns. Cuttlefish can change their skin color, pattern, and even texture in milliseconds using specialized chromatophore cells to match any substrate. The Arctic hare shifts from brown in summer to white in winter through seasonal molting. Transparency is used by glass frogs whose translucent skin reveals internal organs, blending them against green leaves. Some predators like the orchid mantis use aggressive camouflage, resembling flowers to lure pollinators close enough to ambush.
