Super Senses Class 5 EVS Chapter 1 CBSE Notes

Super Senses Class 5 EVS Chapter 1 explains the special sensory powers of animals that help them survive in their surroundings. These CBSE notes describe how animals use sight, smell, hearing, touch, and taste to find food, sense danger, and communicate. Students learn about examples such as dogs’ sharp sense of smell, eagles’ strong eyesight, and snakes sensing vibrations. The chapter helps children understand unique animal adaptations and respect nature. Written in simple language, these notes make learning easy and interesting while helping students prepare well for exams and build curiosity about the natural world.

Understanding Animal Perception with Super Senses Class 5 EVS Notes

Animals don't experience the world the same way humans do. While we rely heavily on our vision, many creatures possess heightened abilities that seem like superpowers. These super senses of animals class 5 notes highlight that some animals can see objects from miles away, hear the softest whispers, or detect smells across vast distances. If you're looking for a structured way to study, a super senses class 5 notes pdf can help you organize these fascinating biological facts. We'll explore how ants follow invisible trails, why dogs sniff everything in their path, and how birds detect predators before they even strike.

The Remarkable Sense of Smell in the Animal World

Smell is a primary tool for survival. Ants provide a perfect example of this. When ants move, they leave a scent trail called pheromones on the ground. Other ants follow this smell to find the path to food or return to their nest. You've likely seen a line of ants moving perfectly in order; they aren't looking at each other, they're "smelling" the road ahead.

Dogs use smell to mark their territory. A dog can tell if another dog has entered its area by sniffing urine or excrement left behind. This acts like a chemical message board. Similarly, mosquitoes use smell to find humans. They're attracted to the scent of our bodies, the heat we emit, and specifically the smell of our feet. Silkworms take this even further; a male silkworm can find its female partner from many kilometers away just by her scent.

Vision and Sight: Seeing Beyond the Human Range

Birds of prey like eagles, kites, and vultures have vision that is four times sharper than ours. If we can see something from two meters away, these birds can spot it from a distance of eight meters. This allows them to identify small prey on the ground while soaring high in the sky.

The way animals see colors is also different. Animals that stay awake during the day can see some colors, though not as many as humans. However, nocturnal animals—those that stay awake at night—view the world in a very different palette. They can only see things in black and white. This is a vital part of their adaptation to life in the dark, where color recognition isn't as important as detecting movement and light contrast.

The Power of Hearing and Sound Communication

Some animals have ears that you can easily see, like elephants or rabbits, while others have internal ears. There's a link between the size of an animal's ears and its hearing capability. Large ears often help in catching more sound waves.

Sound is used for warning others about danger. A langur, for instance, climbs high in a tree to make a special warning call when it spots a tiger or leopard. Birds also have different warning calls for different types of threats, such as a specific sound for a predator in the sky versus one on the ground. Fishes communicate using electric signals in the water. Even dolphins create unique sounds to talk to one another and share information about their surroundings.

Deep Sleep and Seasonal Habits of Animals

You won't see a lizard in your house during the cold winter months. This isn't because they've left; they go into a long, deep sleep. This behavior is a survival strategy to cope with temperatures they can't handle.

The sloth is a famous example of a sleepy creature. It spends almost 17 hours a day sleeping while hanging upside down from a tree branch. Sloths live for about 40 years and only move to about eight trees during their entire lifetime. They are so inactive that they only come down from the tree once a week to relieve themselves. In contrast, a cow only sleeps about four hours, while a python sleeps for 18 hours and a giraffe for a mere two hours.

The Tiger: A Master of Super Senses

The tiger is one of the most alert animals on the planet. Its whiskers are extremely sensitive and can sense movements or vibrations in the air. This helps the tiger move through the dark and find its prey. A tiger’s sense of hearing is so sharp that it can distinguish between the rustling of leaves and the sound of an animal moving on the grass.

Their ears can move in different directions to catch sounds from all around. Furthermore, tigers make different sounds for different purposes, like a roar to warn others or a snarl when angry. A tiger’s roar is so powerful it can be heard up to three kilometers away. Like dogs, tigers mark their area with urine and can instantly tell if another tiger is in their territory by the smell.

Protecting Our Wildlife: The Threat to Animals

Despite their super senses, many animals are in danger. Poachers kill animals for their body parts. Elephants are hunted for their tusks, rhinoceroses for their horns, and tigers, crocodiles, and snakes for their skins. Even musk deer are killed just to make a little scent from their musk.

To protect these creatures, the Indian government has established national parks. Examples include Jim Corbett National Park in Uttarakhand and 'Ghana' in Bharatpur, Rajasthan. In these protected areas, nobody is allowed to hunt animals or destroy the natural habitat. These efforts ensure that the delicate balance of nature is maintained and that these animals can use their super senses to thrive in the wild.

Summary of Animal Senses and Behaviors

When we look at a super senses class 5 summary, we see a world of diverse abilities. Whether it is the snake feeling vibrations on the ground (since they have no external ears) or the eagle spotting a mouse from the clouds, these traits are essential. We must respect these animals and understand that their "super" abilities are what keep the ecosystem functioning. At the end of the day, humans and animals share this planet, and knowing how they perceive us is the first step toward conservation.
