Do giraffes have blue tongues? The answer lies in this writing. Let's see to discover the best answer for this amazing question

Kết quả hình ảnh cho Why do giraffes have blue tongues?

Melanin, which creates dark pigmentation in skin, is responsible for giraffe tongues' dark color. Although it is unknown exactly why giraffes have tongues that appear blue, purple and sometimes almost black, scientists believe that the animals' tongues have evolved this way for sun protection.

Kết quả hình ảnh cho Why do giraffes have blue tongues?

Giraffes have prehensile tongues that wrap around leaves and can grow to be up to 20 inches in length. When feeding, the animals' tongues are frequently out of their mouths and exposed to sunlight, so the dark coloration serves to prevent them from getting sunburned. The underside of giraffes' tongues is a light pink color because it does not get as much sun and therefore needs less protection.

So without further ado, here are about amazing animal facts what pets can impact on human physical health that you are looking for

Companion animals may improve heart health by lowering blood pressure and regulating the heart rate during stressful situations. In a 2002 study, researchers measured changes in heart rate and blood pressure among people who had a dog or cat, compared to those who did not, when participants were under stress (performing a timed math task). People with a dog or cat had lower resting heart rates and blood pressure measures at the beginning of the experiment than non-pet owners. People with a dog or cat were also less likely to have spikes in heart rates and blood pressure while performing the math task, and their heart rates and blood pressure returned to normal more quickly.They also made fewer errors in their math when their pet was present in the room. All these findings indicated that having a dog or cat lowered the risk of heart disease, as well as lowering stress so that performance improved.

A similar study found that having your dog in the room lowered blood pressure better than taking a popular type of blood pressure medication (ACE inhibitor) when you are under stress. Other research has indicated that the simple act of stroking a pet can help lower blood pressure and cholesterol.

Children’s exposure to companion animals may also ease anxiety. For example, one study measured blood pressure, heart rate, and behavioral distress in healthy children aged 3 to 6 at two different doctor visits for routine physicals. At one visit, a dog (unrelated to the child) was present in the room and at the other visit the dog was absent. When the dog was present, children had lower blood pressure measures, lower heart rates, and less behavioral distress. However, research on the health benefits of child and animal interaction is still limited. Further research is needed on how pets influence child development and specific health outcomes.

Findings suggest that the social support a pet provides can make a person feel more relaxed and decrease stress. Social support from friends and family can have similar benefits, but interpersonal relationships often cause stress as well, whereas pets may be less likely to cause stress. The social support provided by a pet might also encourage more social interactions with people, reducing feelings of isolation or loneliness. For example, walking with a dog has been found to increase social interaction, especially with strangers, compared to walking without a dog.

Among elderly people, pet ownership might also be an important source of social support that enhances well-being. In one study, elderly individuals that had a dog or cat were better able to perform certain physical activities deemed “activities of daily living,” such as the ability to climb stairs; bend, kneel, or stoop; take medication; prepare meals; and bathe and dress oneself. There were not significant differences between dog and cat owners in their abilities to perform these activities. Neither the length of time of having a dog or cat nor the level of attachment to the animal influenced performance abilities. Companion animals did not seem to have an impact on psychological health but researchers suggested that a care-taking role may give older individuals a sense of responsibility and purpose that contributes to their overall well-being.

A large German study collected pet information (dog, cat, horse, fish, bird or other pet ownership) from over 9,000 people at two different times (1996 and 2001). The survey included a number of health, economic, and labor issues, so that respondents would not realize the researchers’ interest in a link between pets and health. Researchers found that people who said they had a pet in both 1996 and 2001 had the fewest doctor visits, followed by people who had acquired a pet by 2001; the group of people who did not have a pet at either time had the highest number of doctor visits. Similarly, a study of women in China found that those who were dog owners had fewer doctor visits, took fewer days off sick from work, and exercised more often than non-dog owners.

Research on allergies and asthma is mixed. Some studies show that having a cat might increase allergen sensitivity, while others show it might protect against cat allergies. Having a dog might not influence or might protect against specific dog allergies. A 2013 study found that mice were protected against allergies when they were exposed to dust that came from homes with dogs. The researchers discovered that the protective effect was due to a certain type of gut bacteria that is often present in people with dogs. More research is needed on the connection between allergies, asthma, and pets, but it is possible that the impact of having pets on allergies may depend on the age of the person at the time they are exposed to an animal as well as the type of pet. For example, 6 and 7 year old children who lived with a bird during their first year of life were more likely to have respiratory symptoms like wheezing compared to children who did not have a bird in the home as an infant. Likewise, researchers say that the timing of when a pet is in the family is also important. Children with dogs or cats in their home during the first year of life are less likely to develop allergies in childhood.

As is true with any relationship, some human-pet relationships are likely to be more rewarding than others. Some people are more attached to their pets than others and those feelings could influence the impact of the pet on the person’s health. Other factors such as gender and marital status may play a role. For example, one study found that dog ownership was associated with lower rates of depression among women, but not men, and among single individuals but not married people. So, while pet ownership might have a positive impact on well-being for some people, it doesn’t affect everyone the same way.

How much do you know about penguin facts? Do you know why Penguins are birds but can't fly? Here is answer

Unlike most birds who take to the sky to get around, penguins have adapted to be excellent swimmers and divers. Penguins evolved from ancestors who could fly, but adapted to diving and swimming. While they may not be able to fly through the air, they are experts at flying through the water.


Diving

Penguins are expert divers, with species like the Emperor penguin capable of plunging 1,500 feet under water. In order to accomplish this feat, their wings are structured differently from flying birds. They have short, stubby wings that act more like flippers than the wings of flying birds. Unlike most birds that swim, penguins use their modified wings to propel themselves rather than their feet. A small wingspan reduces drag when they are diving. Dense, solid bones, not hollow, allow them to dive rather than just float on the water.

Energy Efficient

While no other species of bird are capable of swimming quite like penguins, there are some birds that swim and still manage to fly. The thick-billed murre is a bird that is closely related to penguins, but is capable of flight as well as the ability to swim. It requires a lot of energy for the murre to fly, having to beat its wings much faster than other flying birds in order to take to the air. According to National Geographic, the thick-billed murre uses more energy than any other bird in order to fly. At some point during the penguin’s evolutionary history, it was more energy efficient for penguins to give up flying all together and focus their energy instead on diving and swimming to capture food.


Access to Food

Another reason penguins lost their ability to fly was to become more competitive for food under water. By being more efficient divers, penguins were able to access deeper depths than other seabirds. This gave them access to food sources other birds weren’t capable of reaching. Penguins spend as much as 75 percent of the lives in the water, coming on shore for molting and breeding. Penguins eat krill, squid or fish depending on the species, and only eat while at sea. During their time on land, penguins fast.

Too Big

Part of what prevents a penguin from being able to fly is their large bodies. Penguins’ larger bodies facilitate in diving deeper and longer. Unfortunately, their heavier bodies make them too heavy to fly. A larger body also helps keep penguins insulated in the freezing cold waters they dive into. Their unique body shape is streamlined for gliding through the water.

1- Foxes are members of the dog family. A female fox is called a “vixen”, a male fox is called a “dog fox” or a “tod” and baby foxes are called “pups”, “kits” or “cubs”. A group of foxes is called a “skulk” or a “leash”, review journal

2- Foxes are the only type of dog capable of retracting their claws like cats do. Foxes also have vertical pupils that look more like those of cats than the rounded pupils that other dogs have.
3- There are many different types of foxes, and they are the most widespread species of wild dog in the world. Foxes live just about everywhere – in the countryside, cities, forests, mountains and grasslands. Arctic foxes live in cold climates far north, and fennec foxes live in the North African desert.
4- When fox pups are born, they are unable to see, hear or walk, and their mother must take good care of them. When the pups are young, their father hunts and brings food back for the family.
5- Sadly, some cruel people continue to hunt foxes and ridiculously call it a “sport”. In 2004, a law was enacted in England and Wales to ban hunting foxes with dogs, an activity in which hunters would ride on horses following a number of dogs who would pursue the exhausted fox before ripping the animal apart. However, hunters can still hunt and kill foxes by other means. Fox hunting with dogs is still legal in many other places, such as Ireland, North America and Australia.

6- Foxes eat just about anything, including berries, worms, spiders and small animals such as mice and birds. If they live in the city, they eat rubbish that people leave out. If they have extra food, they hide it in a small hole and eat it later when they are hungry.
7- Foxes have beautiful fur, and as a result, the heartless fur industry both breeds captive foxes and traps foxes in the wild. Eighty-five percent of the fur industry’s skins come from animals living in captivity on fur factory farms. At these farms, animals are kept in small cages and are unable to take more than a few steps back and forth. Because fur farmers care only about preserving the quality of the fur, they use slaughter methods such as anal electrocution that keep the fur intact but result in extreme suffering for the animals.
8- Grey foxes who live in North America are the only type of dogs who can climb trees!
9- A fox’s home is called a “den”. It can be a hole in the ground or elsewhere, such as under a garden shed. Hunters often try to scare foxes out of their dens by sending in dogs so that the hunter can then shoot the foxes. Sometimes the foxes remain in the den and are injured or killed by the dogs.

10- Foxes show great caring, adaptability and intelligence when raising their young. The Daily Mail reported in May 2009 that a baby fox cub was caught in a snare for two weeks before being rescued by the RSPCA. He was unable to escape and was badly injured. He survived only because his mother brought him food while he was trapped.

Duck Trivia
  • All types of ducks are part of the bird family Anatidae, which also includes swans and geese. There are species of ducks found worldwide on every continent except Antarctica. Some duck species, such as the mallard, are found throughout the world, while others have very restricted ranges.
  • baby duck is called a duckling, and an adult male is a drake. An adult female duck is called a hen or a duck, and a group of ducks can be called a raft, team or paddling. Generic terms like bird, chick and flock also apply to ducks.
  • All ducks have highly waterproof feathers as a result of an intricate feather structure and a waxy coating that is spread on each feather while preening. A duck's feathers are so waterproof that even when the duck dives underwater, its downy underlayer of feathers will stay completely dry. The uropygial gland produces that waxy oil that coats feathers so well, and many other birds also have the same gland.
  • Ducks are precocial, which means that ducklings are covered with down and able to walk and leave the nest just a few hours after hatching. This helps protect the young chicks from predators, since they do not need to stay in the vulnerable nest area for long.
  • A hen will lead her ducklings up to a half mile or more over land after hatching in order to find a suitable water source for swimming and feeding. As soon as a baby duck's down is dry after hatching, they will be able to swim.
  • Male ducks have an eclipse plumage similar to females that they wear after the breeding season for about a month as their new feathers grow. During that month, they are completely flightless and more vulnerable to predators. At this time, many male ducks stay in isolated, remote areas or flock together for protection in numbers.
  • Most duck species are monogamous for a breeding season but they do not mate for life. Instead, they will seek out new mates each year, seeking the healthiest, best mate who can help them pass on their genes to a new duckling generation.
  • When constructing her nest, a hen will line it with soft down feathers she plucks from her own breast. This gives the eggs the best possible cushioning and insulation. Other duck nesting material includes grasses, mud, twigs, leaves and other plant material.
  • Ducks are omnivorous, opportunistic eaters and will eat grass, aquatic plants, insects, seeds, fruit, fish, crustaceans and other types of food. Some ducks, such as mergansers, are more specialized in their dietary needs, but most ducks can adapt well to different food sources. This helps ensure they always have adequate food to eat.
  • A duck's bill is specialized to help it forage in mud and to strain food from the water. A hard nail at the tip of the bill helps with foraging, and the lamellae, a comb-like structure on the sides of the bill, strains small insects and crustaceans from water.
  • Most male ducks are silent and very few ducks actually "quack." Instead, their calls may include squeaks, grunts, groans, chirps, whistles, brays and growls. Females can also make a wide range of different noises, and they are usually more vocal than males.
  • It is a myth that a duck's quack won't echo. This has been conclusively disproved through different scientific acoustic tests, and was even featured as "busted" on an episode of the Discovery Channel show Mythbusters.
  • Ducks have been domesticated as pets and farm animals for more than 500 years, and alldomestic ducks are descended from either the mallard or the Muscovy duck. Mallards, especially, are easy to crossbreed with other types of ducks, and mallards often hybridize with all types of ducks at local ponds.
  • There are more than 40 breeds of domestic duck. The white Pekin duck (also called the Long Island duck) is the most common variety raised for eggs and meat, especially on large commercial farms. Smaller organizations or individual farmers often try different duck breeds depending on their needs and tastes.
  • Because of their familiarity and comic nature, ducks are often featured as fictional characters. The two most famous fictional ducks are Disney's Donald Duck, who premiered in 1934, and Warner Bros.' Daffy Duck, who premiered in 1937. Ducks have also been spokesbirds for companies or featured in advertising campaigns.
