Adaptive organss in fish and how they corelate with each other
Answers
Answer:
Fish display a wide variety of colors and color patterns. Skin coloration can have many functions. Many fish have color patterns that help them blend in with their environment. This may allow the fish to avoid being seen by a predator. Some fish, such as the flat fishes (Pleuronectiformes), can change their skin coloration to match the surrounding habitat.

Fish can also have disruptive markings to hide body parts. Species such as the jackknife fish (Equetus lanceolatus), high-hat (Equetus acuminatus) and some angel fishes (Pomacanthidae), have dark lines that run through the eyes. These lines may serve to hide the eyes so that other animals can not tell where the fish is looking or even if it is a fish. Also, horizontal lines may be a sight-line for aiming attacks on prey. Some fishes, like butterflyfishes (Chaetodontidae), have spots on their body that resemble eyes. This may serve to confuse prey and predators alike. In addition to coloration, some fish, like the sea dragon (Phyllopteryx), have body shapes that can further mimic their habitat.
