Now listen to part of a lecture in a biology class.
(Female Professor) Now many sea animals, in order to hide from predators, have, over time, developed different kinds of camouflage to help them blend in with their environment and avoid detection by predators.
Picture the surface of the sea floor, it’s as varied as the land we live on. It’s got peaks and valleys, vegetation, rocky areas, and some sea animals have developed permanent colors or shapes to resemble these environmental features. This camouflage helps to disguise them from predators by enabling them to blend into, uh, a specific part of the sea. For instance, take a kind of fish like the Leafy Sea Dragon, well, the name says it all, it resembles a small green dragon with leaf-like protrusions sticking out like arms. Now because its colors and shapes, it blends in extremely well with green sea plants. So when the Leafy Sea Dragon is swimming through these plants, predators have trouble seeing it. But when it enters other environments without these green plants, its camouflage doesn’t work anymore.
Now other sea animals are difficult to spot anywhere in the sea because their type of camouflage enables them to change color. Take the Cuttlefish, a fish that is closely related to the squid and octopus, unlike Leafy Sea Dragons, Cuttlefish have not developed any particular shape to hide from predators. But, uh, they have a lot more mobility because their camouflage allows them to blend in to any environment, because Cuttlefish have shifting pigments that allow them to change color in a matter of seconds, and, so they can almost instantaneously match their color of their surroundings. If they’re swimming by green sea plants, they’ll turn green. And if they’re swimming over the brown sea floor, they’ll turn brown.
Question:
Using the examples of Leafy Sea Dragon and the Cuttle fish, describe two kinds of camouflage and the benefits they provide.
