Super Senses (English) Video Lecture | EVS Class 5

0:0:0: have you ever seen the ants on any sweet
0:0:2: eatable
0:0:4: monkey snatching items
0:0:6: ants moving in a line
0:0:8: so why does this happen
0:0:10: think and tell me
0:0:12: this is because animals also have
0:0:14: different senses just like humans
0:0:18: can you name the five senses which we
0:0:20: have
0:0:22: we can see from the eyes
0:0:24: here from the ears
0:0:26: taste from the tongue
0:0:28: smell from the nose and feel from the
0:0:30: skin
0:0:32: animals also have these superpowers
0:0:35: they can see yeah taste smell and feel
0:0:41: these senses and animals are stronger
0:0:43: and more developed than human beings
0:0:46: therefore these senses in animals are
0:0:48: known as super senses
0:0:52: that is the reason why the ants follow
0:0:54: their friends by their smell and the
0:0:56: monkeys see their prey
0:0:58: so now we know that animals to have
0:1:0: super senses
0:1:2: let us now study in detail the super
0:1:5: senses acquired by different animals
0:1:9: first we will talk about ants we just
0:1:12: saw ants moving in a line
0:1:15: so can you tell me how did the ant
0:1:17: recognize a friend
0:1:19: and use antony to smell touch feel and
0:1:22: communicate with other ends
0:1:25: as the ants move they leave a smell on
0:1:27: the ground
0:1:29: the other ends follow the smell to find
0:1:31: the way
0:1:32: with the help of these special senses
0:1:34: the ants learn about other ants that are
0:1:37: part of its group
0:1:40: now think of an incident where you got
0:1:42: frustrated because of a mosquito
0:1:45: you all might have experienced it
0:1:48: but how did mosquito find us
0:1:51: mosquitoes can find us by the smell of
0:1:54: our body the smell of the soul of our
0:1:56: feet and the heat of our body
0:1:58: also some male insects can recognize
0:2:1: their females by their smell
0:2:4: let us talk about dogs now
0:2:6: have you ever seen a dog sniffing
0:2:9: we all have
0:2:11: this is because the dogs have a super
0:2:13: sense of smell
0:2:15: they can even smell the faintest smell
0:2:17: too
0:2:18: dogs mark out their own area on the road
0:2:22: they can make out if another dog has
0:2:24: come into their area by the smell of its
0:2:26: urine or potty
0:2:28: this special sense of smell of dogs is
0:2:30: used by humans for catching criminals
0:2:33: and for detecting undesirable things or
0:2:35: bombs
0:2:38: next we move on to birds
0:2:41: students can you tell me about a bird
0:2:43: that has eyes on both sides of the head
0:2:46: yes yes
0:2:48: most birds like sparrows crows pigeons
0:2:51: eagles etc have their eyes on either
0:2:54: side of the head
0:2:56: when they look straight ahead their eyes
0:2:58: focus on the same object
0:3:0: in most birds eyes are fixed and cannot
0:3:3: move
0:3:4: so birds have to turn their heads to see
0:3:7: around
0:3:9: now we talk about the birds who have
0:3:11: eyes in front
0:3:13: an owl has eyes in front of its head
0:3:15: like in humans
0:3:17: so when a bird focuses both eyes on an
0:3:20: object it can estimate the distance
0:3:23: when its eyes focus onto different
0:3:25: things it increases its range of vision
0:3:29: with two eyes the span of vision
0:3:31: increases
0:3:33: let us look at some important points
0:3:36: some birds like kites eagles and
0:3:38: vultures can see four times as far as we
0:3:41: can
0:3:43: that is these birds can see things from
0:3:45: a distance of eight meters what we can
0:3:47: see from a distance of two meters
0:3:50: an eagle in the sky can see a prey on
0:3:52: the ground from a distance of one and a
0:3:54: half to two kilometers
0:3:57: so here comes another question for you
0:4:0: do animals see colors
0:4:3: the correct answer is that animals
0:4:5: cannot see as many colors as we can
0:4:8: it is believed that animals that are
0:4:10: awake in the daytime can see some colors
0:4:13: like pro
0:4:14: while those animals that are awake at
0:4:16: night can see things only in black and
0:4:19: white colors like owl
0:4:22: let us discuss the ears of animals and
0:4:24: the sounds they hear
0:4:26: can you name an animal whose ear you
0:4:28: cannot see
0:4:30: absolutely yes
0:4:32: we cannot easily see birds ears
0:4:35: their ears are small holes covered with
0:4:37: feathers
0:4:38: but what if i can ask you to name the
0:4:40: animals whose ears are bigger than yours
0:4:44: yes there are many animals
0:4:46: the large ears of animals can collect
0:4:48: more sound waves making their hearing
0:4:51: power stronger than ours
0:4:53: as you can see snakes do not have
0:4:55: external ears
0:4:57: that means you cannot see them
0:5:0: they only feel the vibrations on the
0:5:2: ground
0:5:3: next we talk about language
0:5:6: high up on a tree a langur warns others
0:5:9: of dangers like a tiger
0:5:12: the lungur does this by making a special
0:5:14: warning call
0:5:17: what about birds
0:5:19: birds also give alarm calls to warn
0:5:21: about the danger
0:5:23: some birds even have different sounds
0:5:25: for different kinds of dangers
0:5:28: even fishes give alarm calls by electric
0:5:30: signals
0:5:32: dolphins also make different sounds to
0:5:34: give messages to each other
0:5:37: some pet animals like dogs cats and
0:5:39: parrots can be trained to understand our
0:5:42: language
0:5:43: we all love sleeping
0:5:46: don't we
0:5:47: and we usually sleep for six to eight
0:5:49: hours per day
0:5:51: but some animals go into a long deep
0:5:53: sleep in certain seasons
0:5:56: then they are not seen for many months
0:5:59: also have you ever wondered why lizards
0:6:2: are not seen in winters
0:6:4: this is because they go to sleep during
0:6:6: entire winters
0:6:8: a sloth is one of those animals which
0:6:11: looks like a beer but is not
0:6:13: it spends almost 17 hours a day sleeping
0:6:16: while hanging upside down on a tree
0:6:18: branch the sloth eats the leaves of the
0:6:21: same tree on which it lives
0:6:24: and when it has it in enough leaves from
0:6:26: that tree it moves to the nearby tree
0:6:29: they live for about 40 years and move
0:6:31: around only 8 trees
0:6:34: slots come down once a week from the
0:6:36: tree to relieve themselves
0:6:39: the tiger is one of the most alert
0:6:41: animals yet it is in danger
0:6:44: can you tell me some amazing facts about
0:6:46: tidals let us have a look
0:6:49: a tiger can see six times better at
0:6:52: night than most of us
0:6:54: the tigers whiskers are very sensitive
0:6:56: and can sense the movements or
0:6:58: vibrations in the air and that helps
0:7:0: them to move in the dark and find their
0:7:2: prey
0:7:4: tigers also make different sounds for
0:7:6: different purposes like when it is angry
0:7:8: or to call out to a tigress
0:7:11: each tiger has its own area which may
0:7:13: cover several kilometers and mark their
0:7:16: area with its urine
0:7:19: let me now tell you an interesting fact
0:7:21: about animals
0:7:23: animals are killed and their parts are
0:7:25: sold
0:7:26: can you name an animal and a product you
0:7:28: use made from it
0:7:30: pause the video and think
0:7:32: now i have some examples for you
0:7:35: elephants are killed for their tusks
0:7:38: the task is the teeth of an elephant
0:7:40: that is used to make jewelry
0:7:42: secondly rhinosaurus are killed for
0:7:45: their horn
0:7:46: you can see here that the horn is used
0:7:48: to make ornaments
0:7:50: tigers crocodiles and snakes are killed
0:7:53: for their skins
0:7:55: the skin of these animals is used to
0:7:57: make leather products light belt
0:8:0: lastly musk deer are killed to make
0:8:2: scent from their musk
0:8:4: now what do we call the people who kill
0:8:7: animals
0:8:8: people who kill animals are called
0:8:10: hunters and poachers
0:8:13: with this we come to an end of the
