3examples from finding nemo of organisms that use camouflage as an adaptation to survive

The Flounder (Mr. Johansen in Finding Nemo), uses coloration technique as camouflage by imitating or blending in the colors and textures of the ocean floors. The Puffer Fish (Bloat). Aside from being able to make itself appear big to drive away the predators, it can also blend in the ocean floors and rocks similar of its color. Regal Tang (Dory) uses camouflage as well. This kind of fish is known for its bright and vivid colors, but when it senses harm, it can make itself somewhat see-through and easily blends with the colors of its surroundings.
