Oxygen minimum zones (OMZs), large midwater regions of very low oxygen, are expected to expand as a result of climate change. Its color is yellow, orange, or red and is the most abundant carotenoid in nature . Other physical adaptations include gray or black color, which acts as a camouflage in the deep sea environment, and bioluminescence, i.e., the ability to produce light by physiological processes, which helps the species lure their prey.
