What is the loudest animal sound?

What is the loudest animal sound? Let's see the answer here

The sound of the blue whale, which measures 188 decibels and travels up to 500 miles, is the loudest among all animals, according to the Smithsonian National Zoological Park. On land, the loudest animal sound comes from the howler monkey and can be heard for up to 3 miles.



Scientists also measure the sounds that animals make relative to their size. Using this ratio, the loudest animal sound is produced by an insect called the water boatman. This tiny bug measures in at less than 0.08 inches, but it emits a singing sound that can measure as high as 99.2 decibels. Its average noise level is 78.9 decibels.

Cool elephant teeth facts

How many teeth do elephants own? Can you guess? If you can't, just keep reading this writing about elephants for kids to have the best answer for this question.

Most mammals have a set of baby teeth that eventually fall out and are replaced by adult teeth, which they keep for their entire lives. Elephants are different, however. They go through six sets of large, brick-like teeth that grow in at the back of their mouths and slowly move to the front as they are worn down. The teeth then fall out and are replaced by fresh ones.

Consequently, elephants have no use for dentists, and have been known to laugh openly when they encounter dental hygienists on safari. There is evidence of elephants in the wild eating five hundred pounds of coconut macaroons in one day, without flossing.

Kết quả hình ảnh cho do elephants have teeths?

Each set of elephant teeth that grows in is larger than the last. The final teeth are over eight inches long (21 cm) from front to back and weigh more than eight pounds (4 kg).

When an elephant's final set of teeth falls out, the elephant slowly dies of malnutrition or starvation. This is a pretty poorly designed animal, if you ask me.

Old elephants will seek out wet, marshy areas where the plants are softer, so they can more easily eat them. However, in the end, this doesn't really help and they die anyway, much to the amusement of vacationing dental hygienists.

Why does a dog howl?

Here is the answering for an interesting question: Why do dogs howl? There are a number of reasons. Some that are no big deal, and others that should be addressed.

Kết quả hình ảnh cho why dogs howl

AncestryThink your dog sounds like a howling wolf? That’s probably because dogs are distantly related to wolves, and the urge to howl is still embedded in their genetic code. Sometimes they don’t even know why they’re doing it, just that it’s what they’re supposed to be doing. Howling is totally normal and natural as long as it’s not chronic, pervasive, or invasive.

Communication
In the wild, wolves howl to tell a lost member of their pack where they are or to ward off another animal that’s encroaching on their territory. For domesticated dogs, this may translate to howling at sirens (“Hey, I’m over here!”), howling when a strange dog comes near (“Too close, buddy!”), or both.

Howling like the above two examples should be expected and isn’t anything to worry about as long as it isn’t accompanied by aggression toward other dogs or people. Most dog owners even tend to find it pretty cute. However, there are situations where howling is a symptom of something deeper that needs to be fixed.

Sickness and injuryOne of the ways that many dogs express the fact that they are hurt or sick is by howling or vocalizing in other ways. If you notice that your dog is making strange sounds or “talking” more than normal, get them to the vet for a check-up.

Separation anxietyRemember how wolves howl to find each other in the wild? Well, if your dog is suffering from separation anxiety, it’s possible that he’ll start doing this every time you leave — not fun for you, the dog, or your neighbors.

How do you know that the howling is being caused by separation anxiety? Because it’s usually accompanied by another symptom, such as destroying things, pacing around, or eliminating inside the house. Howling of this kind will take time and consistent effort to overcome.

Wide range of interesting facts about science

If you’re looking for the most amazing science facts, you’re at the right place. Here are list of amazing facts about science:

1. Water can boil and freeze at the same time
Seriously, it's called the 'triple point', and it occurs when the temperature and pressure is just right for the three phases (gas, liquid, and solid) of a substance to coexist in thermodynamic equilibrium. This video shows cyclohexane in a vacuum.

2. Lasers can get trapped in a waterfall

Oh my gosh, yes. Not only is this an incredible example of total internal reflection, it also shows how fibre optic cables work to guide the flow of light.

3. We've got spacecraft hurtling towards the edge of our Solar System really, really fast

We all know rockets are fast, and space is big. But sometimes when we're talking about how long it takes for us to get to distant parts of the Solar System (eight months to get to Mars, are you kidding me?) it can feel like our spacecraft are just crawling along out there.

This gif shows just how wrong that idea is by comparing the speed of the New Horizons probe, which flew past Pluto last year, to a 747 and SR-71 Blackbird.

4. An egg looks like a crazy jellyfish underwater

A cracked egg on land might make a big mess, but 18 metres (60 feet) below the surface of the ocean, the pressure on the egg is 2.8 times atmospheric pressure, and it holds it all together like an invisible egg shell. True story.

5. You can prove Pythagoras' theorem with fluid

Not buying what your maths teacher is selling when they tell you a2 + b2 = c2? You can actually prove it with liquid.

6. This is what happens when a black hole swallows a star
NASA

As the star gets sucked up into the black hole, a huge jet of plasma is burped out, spanning hundreds of light-years. "When the star is ripped apart by the gravitational forces of the black hole, some part of the star's remains falls into the black hole, while the rest is ejected at high speeds," explains Johns Hopkins University researcher, Suvi Gezari.

7. You CAN see without your glasses
According to MinutePhysics, all you need to do is make a pinhole with your hand, which will help you focus the light coming into your retina. Sure, it won't give you 20/20 vision, but it's a good start if you've left your glasses at home.

8. This is how a face forms in the womb

Embryonic development is an incredibly complex process that scientists are still just beginning to understand. But one thing researchers have been able to map out is how the embryo folds to create the structures of the human face in the womb. We could watch this all day.

Fun time facts for kids

I see it somewhere and share to all of you because of its amazing. Enjoy!

Learn the basics while reading about the history of timekeeping and thinking about some of the more philosophical questions related to time. Have fun exploring all our information on the interesting topic of time. 

Interesting Time Facts for Kids

We use time to order events in the past, present and future. We also use it to make comparisons and measure the speed at which things move.

If you wanted to measure time you could use a watch, clock, hourglass or even a sundial.

A sundial is a tool that uses the position of the Sun to measure time, typically involving a shadow cast across a marked surface.

The use of pendulums to accurately measure time was discovered by Galileo Galilei around 400 years ago. A pendulum is a free swinging weight hanging from a pivot.

There are 60 seconds in a minute, 60 minutes in an hour and 24 hours in a day.

Normal years have 365 days but a Leap year has 366. The Earth takes a little longer than 365 days to go around the Sun so we add an extra day in February every four years (with a few exceptions) to keep calendars and seasons aligned.

10 years is known as a decade, 100 years is known as a century and 1000 years is known as a millennium.

Milliseconds, microseconds and nanoseconds are examples of very small units of time.

Planck time is the name given to the smallest known unit of time. It’s a little confusing but it measures the amount of time it takes light to travel 1 Planck length (a distance so small that it can’t even be measured!).


Scientists believe the moon was used as a form of calendar as far back as 6000 years ago. Calendars have been changing ever since and are very accurate in modern times.

Accurate clocks that measure hours, minutes and seconds have improved with the invention of sundials, water clocks, mechanical clocks, pendulums and hourglasses through to the digital displays and atomic clocks of today.

Many places use daylight saving time (typically by putting clocks forward an hour) for longer daylight in the evenings.

Different parts of the world are located in different time zones. This means that while you are having breakfast in the morning, someone in another part of the world is having dinner.

Theories related to time have been put forward by famous scientists such as Isaac Newton and Albert Einstein. You may have even heard of the term ‘spacetime’, a model in physics that joins space and time together.

In terms of philosophy, time is difficult to define. Scientists and philosophers have disagreed on our understanding of time for many years. Some argue it is a ‘real’ part of the Universe while others argue it is just the way humans think, comparing events and putting them in sequence. It’s a little confusing but fun to think about, what do you think?


How much do you know about human hand facts?

How much do you know about human hand facts? Check it below:

  • Hands are the things making our life really tough if we lose them. Below are some amazing facts about the really amazing body part.
  • One out of three every emergency acute injuries is related to upper limbs.
  • And two out of upper limb injuries happen within people’s working years.
  • In the U.S., disable injuries at work are most common with upper extremities at the rate of 25% of all disable work injuries.
  • 25% of athletic injuries involve hand and wrist.
  • Fingers have no muscles. The muscles bending the finger are situated in the palm and up to mid forearm. They are linked to the finger bones by tendons to move the fingers as strings seen in a marionette. 


  • The wrinkles on the back of fingers are the mark of where the skin is attached to the tendon.
  • Here are major statistics about hand. There are 29 major and minor bones (many people have a few more) with 29 major joints. Scientists gave name for at least 123 ligaments. 34 muscles are in charge of moving the fingers and thumb: 17 in the palm of the hand, and 18 in the forearm. 48 named nerves: 3 major nerves, 24 named sensory branches, 21 named muscular branches. 30 arteries and nearly as many smaller branches are named.
  • The thumb is controlled by 9 individual muscles, which are controlled by 3 major hand nerves.
  • 90% of women and 80% of men at the age from 75 to 79 have osteoarthritis in their hands.
  • Fingernail has no feeling, but the skin beneath the nail does. Loss of a fingernail can cause changes in feeling on the opposite side of fingertip.
  • One-fourth motor cortex in human brain whose area controls all movement of body is spent on muscles on hands.
  • Structurally, fingernails are modified hairs.
  • Skin of palm has no hair, has unique fingerprints. It cannot get tanned. It is tough, durable but sensitive.
  • The Hand has been used as a symbol of protection since ancient times.

  • We use our hands everyday and it is almost impossible to imagine our life without them. But what do we know about our most active parts of the body. The following are the most interesting facts about our hands and arms:
  • There are no muscles in your fingers. The muscles that move your fingers are located in the palm and up in the mid forearm. They're connected to the finger bones by tendons which pull and move the fingers like the strings of a marionette.
  • The Hand has been used as a symbol of protection since ancient times.
  • Your fingernails grow about the same amount as the Continents move every year.
  • It takes 6 months for your fingernails to grow all the way from the root to the tip. Your toenails take 2-3 times as long.
  • The longest Fingernails ever belonged to Shidhar Chillal. They were 20 feet, 2.25 inches! It took 48 years to grow them.
  • 12.6% of all men are left-handed, while only 9.9% of all women are.
  • One third of all acute injuries seen in emergency rooms involve the upper extremities.
  • One fourth of athletic injuries involve the hand and wrist.
  • When the hand is kept wet, the skin of the palm wrinkles. Why? The exact mechanism is not known, but it is clearly controlled by nerves. When the nerve which supplies feeling to an area of skin on the palm is cut, that area of skin not only becomes numb, loses its ability to wrinkle when wet. It also loses the ability to sweat.
