How are some fish specially adapted to attract prey or to escape predators?

Fish have adaptable behaviors and structures so that they can survive in the wild. These adaptations however differ with regards to context and environment. Some fishes for example are called stonefish because they can camouflage in environments that are composed variedly with pebbles and rocks, and this helps them to avoid predators and thrive. Nevertheless, when these group of organisms are strayed and become exposed to a new environment they can be exposed and be vulnerable to predators.
