Concept: Animals have different senses. The animal world is full of examples of amazing senses. Explanation: Silkworm: The silkworm is the larva or caterpillar of the Bombyx mori moth. The moth is important because it makes silk. It is entirely dependent on humans, and it no longer lives in the wild. Silkworms eat mulberry leaves and are native to northern China. Some male insects can recognise their females by their smell. Silkworms can find their female worm from many kilometres away by their smell. Important Points Pheromones are chemical agents that are secreted by animals as sexual attractors. Used to anticipate population and to communicate with each other to find food and to warn them from predators. Pheromones are secreted by Exocrine glands present all over the body. Here, it is the phenomenon of Pheromone attraction in silkworms, leading to an equal number of males and females interaction for mating. Hence, silkworm will recognize its female partner by its smell. Additional Information Animals and their super senses: Tiger: ​A tiger can see six times better at night than most of us. The tiger’s whiskers are very sensitive and can sense the movements or vibrations in the air. A tiger’s sense of hearing is so sharp that it can make out the difference between the rustling of leaves and the sound of an animal moving on the grass. The ears of the tiger can move in different directions and this helps to catch the sounds from all around. Tigers make different sounds for different purposes like when it is angry or to call out to a tigress. It can also roar or snarl. Tigers mark their area with their urine. A tiger can at once come to know if there is another tiger in its area by the smell of the urine. Vulture: Vultures can see four times as far as we can. These birds can see things from a distance of eight metres what we can see from a distance of two metres. ​Hawk: Their eyes are forward-facing, which gives them excellent binocular vision. Their eyesight is one of the sharpest among all animals. Their eyes also allow them to focus quickly as they dive.
