Some animals have the ability to change color according to their surroundings. Which of the following animals has its ability?
(a)Butterfly, Bee
(b)Lizard, Tiger
(c)Leaf insect, Chameleon
(d)Polar bear, Penguin
Solution
The organisms having the ability of camouflage here, belong to the phylum Arthropoda and Reptilia respectively. Camouflage is the use, either by rendering animals or objects difficult to see, or by disguising them as something else, of some mixture of textures, coloration, or illumination for concealment.
Complete answer:
-Leaf insects have highly flattened bodies, wings, and legs that are irregularly shaped. Usually, they are between 5-10 cm long (2-4 in length).
-Since their broad, leathery forewings have veins that look similar to the veins on the specific type of leaves they inhabit, they are called leaf insects.
-They are slow-moving herbivores and rely on their camouflage and fore wings to protect themselves against predators such as birds, amphibians, and reptiles. The females live from 4 to 7 months and the males from 3 weeks to 1 month.
-5-6 times in a lifetime, the species moults. Females are heavy-bodied and flightless, and each lays about 500 eggs in a lifetime. At the base, the abdomen is smaller, and the foreleg femur is dilated.
-The color shift has roles in camouflage in chameleons, but most generally in social signaling and in temperature reactions and other situations.
-The relative meaning of these positions varies with the situations, as well as the organisms.
-The change of color signals the physiological state and intentions of a chameleon to other chameleons.
-Because chameleons are ectothermic, another explanation why they change color is to control their body temperatures, either to a darker color to absorb light and heat to increase their temperature, or to a lighter color to reflect light and heat, thus either stabilizing or reducing their body temperature.
So, the correct answer is, ‘Leaf insect, Chameleon’.
Note: -Through evolution and environment, Chameleon color palettes have grown.
-Compared to those living in the desert or savanna, who have more of a simple, brown, and charred palette, chameleons living in the forest have a more defined and colorful palette.
