Can elephants hear with their feet?

The sound waves come from the animals’ huge vocal cords, and distant elephants “hear” the signals with their highly sensitive feet.

Elephants perceive vibrations through the soles of their feet. Vibrations travel up through their bones to their head. They are then amplified by the skull’s bones and transmitted to the ossicles of the ear. The elephant pounds the earth to alert others of danger. Such messages can be perceived at a distance of up to 18.5 mi. (30 km).

To test the theory that elephants transmit and receive underground messages, O’Connell-Rodwell and her colleagues previously conducted several novel experiments with pachyderms in Africa, India and at a captive elephant facility in Texas.

“We went to Etosha National Park in Namibia and recorded three acoustic calls commonly made by wild African elephants,” she says. “One is a warning call, another is a greeting and the third is the elephant equivalent of ‘Let’s go!'”

The researchers wanted to find out if elephants would respond to recordings played through the ground, so they installed seismic transmitters at a tourist facility in Zimbabwe where eight trained, young elephants were housed.

The idea was to convert audible “Greetings,” “Warning!” and “Let’s go!” calls into underground seismic waves that an elephant could feel but not hear directly through the air.

“We used a mix of elephant calls, synthesized low-frequency tones, rock music and silence for comparison,” says O’Connell-Rodwell.

“When the ‘Warning!’ calls were played, one female got so agitated she bent down and bit the ground,” she notes. “That’s very unusual behavior for an elephant, but it has been observed in the wild under conditions of extreme agitation.”

The young female had the same agitated response each time the experiment was repeated. Researchers also played recorded calls to seven captive males.

“The bulls reacted, too, but their response was much more subtle,” notes O’Connell-Rodwell.

“We think they’re sensing these underground vibrations through their feet,” she adds. “Seismic waves could travel from their toenails to the ear via bone conduction, or through somatosensory receptors in the foot similar to ones found in the trunk. We think it may be a combination of both.”

What is the meaning of name rhinoceros?

The literal translation of rhinoceros is ‘nose-horned’. It comes from the Greek word ‘rhinokeros’ from ‘rhinos’ meaning ‘nose’ and ‘keras’ meaning ‘horn of an animal’. 

Rhinoceros are killed by some poachers for their horns, which are bought and sold on the black market, and used by some cultures for ornaments or traditional medicine. East Asia, specifically Vietnam, is the largest market for rhino horns. By weight, rhino horns cost as much as gold on the black market. Some cultures believe the horns to have therapeutic properties and they are ground up and the dust consumed. The horns are made of keratin, the same type of protein that makes up hair and fingernails. Both African species and the Sumatran rhinoceros have two horns, while the Indian and Javan rhinoceros have a single horn. The IUCN Red List identifies the black, Javan, and Sumatran rhinoceros as critically endangered.

The family Rhinocerotidae consists of only four extant genera: Ceratotherium (white rhinoceros), Diceros (black rhinoceros), Dicerorhinus (Sumatran rhinoceros), and Rhinoceros (Indian and Javan rhinoceros). The living species fall into three categories. The two African species, the white rhinoceros and the black rhinoceros, belong to the tribe Dicerotini, which originated in the middle Miocene, about 14.2 million years ago. The species diverged during the early Pliocene (about 5 million years ago). The main difference between black and white rhinos is the shape of their mouths – white rhinos have broad flat lips for grazing, whereas black rhinos have long pointed lips for eating foliage. There are two living Rhinocerotini species, the Indian rhinoceros and the Javan rhinoceros, which diverged from one another about 10 million years ago. The Sumatran rhinoceros is the only surviving representative of the most primitive group, the Dicerorhinini, which emerged in the Miocene (about 20 million years ago).

What are some mind-blowing facts about biology?

1. During pregnancy, the baby in womb can help repair a mother’s organ damage by giving its stem cells. In Biology, it’s a form of chimerism called the Fetomaternal microchimerism (FMc). Alternatively, this is a survival mechanism by which the fetus ensures maternal fitness in order to enhance its own chances of survival.

2. Some humans have a total of 207 bones instead of 206. The Fabella is a tiny sesamoid bone in the knee that has been making a come back in recent years. At present, around 39% of the population have the extra fabella bone, which is three times more in 100 years, compared to only 11% of world population having it in 1918. Scientists theorize, this emergence is due to increased nutrition and humans getting taller and heavier.

3. A newborn baby has only one cup (0.2 liters) of blood in the whole body, whereas, the healthy adult has about 1.3 to 1.6 gallons or 4.0 to 5.0 litres of blood circulating inside their body.

4. Lungs are the only organ in the human body that can float on water. In fact, medical examiners use the “lung float test” during autopsies to determine if a baby was stillborn (died in the womb). If the lungs float, the baby was born alive; if the lungs don’t float, the baby was stillborn.

5. Speaking about lungs, did you know that you can live with just one lung? Patients with lung cancer, can still live healthily even after a lung is removed, retaining at least 70% of their previous respiratory function. Surprisingly, the remaining lung will expand to fill the empty space of the other lung in the chest.

6. If you pulled out the blood vessels from an an average child and laid out in one single line, it would stretch to over 60,000 miles. The entire circumference of the earth at it’s largest is 24,900 miles.

7. Your eyes blink over ten million times a year!

8. The entire surface of your skin is replaced every month, which put another way means you have about 1,000 different skins in your life.

9. Next time you’re wounded, and can’t find a bandage, just ask the friendly spider next wall. Spiderwebs/cobwebs have natural antiseptic and anti-fungal properties, and were used in ancient Greece and Rome by physicians to make bandages. They’re also thought to be rich in Vitamin K. 

10. While you’re sleeping, your ears continue to function. They will pick up sounds, but your brain acts as a filter and blocks out the unimportant ones.

11. More humans are evolving to have three arteries in their arms. The Median artery which is present during the early human embryonic stage is later replaced by the ulnar and radial artery during developmental changes. However new research shows that median artery is now prevalent in about 35% of the population and researchers predict that people born 80 years from now might all carry a median artery. This is an example of Micro-evolutionary changes that are occurring in the human body.

What are some mind-blowing facts about food?

White chocolate is not chocolate
Don’t be fooled by the name of white chocolate. It doesn’t contain any chocolate. It’s actually just a mixture of sugar, milk, vanilla, lecithin and cocoa butter.

Nutmeg is a hallucinogen
If you take a lot of nutmeg, it works like a psychedelic because it contains a natural compound called “myxorubicin.”. If taken in large doses, it can have a mind altering effect. It is also poisonous in large doses.

There is no difference between the wax on the surface of fruit candy and that on the car
The luster of fruit fudge comes from the palm wax of Brazil, which is actually the same type of wax used in cars. I don’t know what you think about this!

Ketchup was once used as medicine
As early as 1800, people believed that tomatoes had medicinal value. Doctors at the time claimed that ketchup could treat diarrhea and indigestion, so it was once used as a pill.

Biscuits are more harmful to your teeth than sugar
Acid is the biggest cause of tooth decay, not sugar! Biscuits tend to stick to your teeth and eventually become a hotbed of bacteria.

Drink more wine in the bar, not because it is good, but because the music is loud
Studies have shown that the volume of music can change people’s drinking habits. Loud music seems to make people drink more and faster.

The validity period of bottled water has nothing to do with water
Water doesn’t expire, but bottles do. Plastic bottles will leak chemical particles into the water over time. Although it will not make the water harmful, it will reduce the freshness of the water.

 Honey is actually the vomit of bees
When bees collect nectar, they take nectar and keep it in their stomachs. Once back in the hive, the nectar is expelled back into the hive.

Sweet drinks can cause dementia
Studies have shown that people who drink one or more artificial sweetened drink a day are three times more likely to develop dementia than others.

What are baby turtles called?

A baby turtle is called a hatchling, while hatchling is most often used for a young bird, tadpoles, newts and new born baby turtles.

Baby turtles are cute little creatures that require totally different care than adult turtles, needing a lot of special care to keep them alive and healthy. They’re prone to many diseases and carry many disease-carrying germs. You have to feed a baby turtle food that is available in the pet store, while supplementing their diets with vegetables, meat and fruit. Land turtles tend to eat more vegetables than those living in water.

The building block of your baby turtle’s diet is the pellet or gel capsule supplement, which is a snap to find in any pet store that sells turtle supplies. There are two caveats, however: you should examine each label to make sure your newborn turtle is getting the best diet possible, and you should select a formula that’s been approved for your particular shelled pet. For example, what a baby box turtle eats is more of a true omnivorous diet than a water turtle eats, which includes more raw meat as a baby but a more omnivorous diet as an adult.

Are turtles reptiles or mammals?

Turtles are reptiles of the order Testudines. They are characterized by a special bony or cartilaginous shell developed from their ribs that acts as a shield. “Turtle” may refer to the order as a whole (American English) or to fresh-water and sea-dwelling Testudines (British English). Testudines includes both extant (living) and extinct species. Its earliest known members date from the Middle Jurassic. Turtles are one of the oldest reptile groups, more ancient than snakes or crocodilians. Of the 356 known extant species, some are highly endangered.

A turtle’s diet varies greatly depending on the environment in which it lives. Adult turtles typically eat aquatic plants,[citation needed] invertebrates such as insects, snails, and worms, and have been reported to occasionally eat dead marine animals. Several small freshwater species are carnivorous, eating small fish and a wide range of aquatic life. However, protein is essential to turtle growth and juvenile turtles are purely carnivorous.

Sea turtles typically feed on jellyfish, sponges, and other soft-bodied organisms. Some species with stronger jaws have been observed to eat shellfish, while others, such as the green sea turtle, do not eat meat at all and, instead, have a diet largely made up of algae.

Can sea turtles feel it when you touch their shell?

Yes, sea turtles can feel it when you touch their shell. Sea turtle shells consist of bones, which are covered by a layer of so-called scutes (plates). These scutes are made of keratin, the same material that human fingernails are made of. There are nerve endings enervating even the bones of the shell. These nerve endings are sensitive to pressure, for example from a touch on the back.

A tortoise’s shell obviously isn’t as sensitive as its skin, but the animals are able to feel the tactile sensations that occur when someone pats, rubs, scratches, or taps it. This has to do with how the shell is physically attached to the tortoise’s body.

One thing that tortoises and turtles have in common is their tendency to recede into their shells when they feel threatened. In the proper care, however, most tortoises appear to enjoy being touched by their caretakers. In some cases, they extend their necks out while being touched or massaged – a sign that the animal wants to be rubbed some more.

Which is the oldest dog in the world?

According to the Guinness World Records, the oldest dog on record was another Australian dog named Bluey, who was 29 years and five months. Bluey died in 1939.

Bluey – or, known by his full name as Bluey Les Hall – lived from 7 June 1910 to 14 November 1939. He was owned by Les and Esma Hall and is officially the oldest dog according to the Guinness Book of World Records.

Bluey’s age is part of what urged a study to be conducted regarding the longevity of the lives of Australian cattle dogs. This study involved one hundred dogs and found that, on average, this breed of dog had the tendency to live about one year longer than other breeds. As such, Bluey’s case is still considered an outlier as he lived a full decade and a half more than the average life expectancy.

How good is a dog’s sense of hearing than humans?

Dogs have a keen sense of hearing. In fact, they are capable of hearing sounds four times further away than the human ear can discern. Their ears are also better designed to gather more available sound waves. They have 15 different muscles that move their ears in all directions. Plus they can move one ear at a time, independently of the other, to absorb even more information.

They can also hear sounds four times further away — so what human ears can hear from 20 feet away; our dogs can hear from 80 feet away.

Even though our dogs can hear better than we can, do they understand what they’re hearing?

Two studies, one published in the journal Current Biology and the other in Science, conclude that the answer is yes! Your dog might not understand everything you say, but he listens and pays attention similar to the way humans do. The researchers discovered that dogs — like humans — respond not only to the words we say to them, but also to the emotional tone of our voices.
