Värinsäätökyky
Värinsäätökyky refers to the physiological ability of an organism to control and adjust the color of its body surface. This is often achieved through specialized pigment cells called chromatophores, which can expand or contract to reveal or conceal different pigments, or by structural modifications that alter light reflection. The primary functions of color change include camouflage, thermoregulation, communication, and predator avoidance.
Many aquatic animals, such as cephalopods (squid, octopus, cuttlefish) and certain fish, exhibit remarkable and rapid
The mechanisms behind värinsäätökyky vary. Chromatophores are the most common cellular basis, containing pigments like melanin,
