10 Incredibly Adaptive Sahara Desert Animals

10. Jerboa

These adorable little rodents have very long legs and can jump very high. Despite their minuteness, they can run up to 16 miles per hour, making them quite challenging to catch. Amazingly, the jerboa doesn’t have to drink water—quite a useful adaptation for a desert creature. It still needs to take in water of course, like all living things, but it is able to extract enough from its foods to sufficed for its needs.

9. Fennec Fox

These foxes are nocturnal and are characterized by their very large ears. Not only do the ears help them to hear better in the desert, but they also help them to release body heat, keeping them cool. They are small and lightweight, usually weighing only a couple of pounds.

8. Monitor Lizard

This large lizard (generally; some can be quite small) is venomous and can become quite aggressive when threatened, especially during colder seasons. Monitor lizards not only include desert-thriving species in the Sahara, but also species which can live in forests or even wetlands. This makes them some of the most versatile creatures on the planet. They are extremely intelligent and can even count.

7. Ostrich

Not a lot of people think of ostriches when asked to name a desert animal, but ostriches are some of the fastest animals in the Sahara. They are able to run up to 40 miles an hour, almost as fast as the gazelles. They can travel a long ways, and can also pick up noises and see movement across vast distances, helping them spot and avoid predators. When threatened, the ostrich can fight back, kicking with its long legs.

6. Sidewinder

There are a number of species of sidewinder in various deserts around the world. The horned viper is particularly well known in the Sahara. The venom from this snake can be lethal, and also quite painful, even in cases that do not lead to death. The unique sideways movement of the sidewinder helps it to traverse the sands quickly and effectively. Sadly, changes in the environment have caused the horned viper to enter the endangered species list.

5. Death Stalker Scorpion

This type of scorpion is translucent and yellow in appearance, and is among the most venomous animals of the Sahara desert, and the entire world. They look ephemeral and fragile, but they are incredibly dangerous, capable of causing respiratory failure and death.

4. Addax Antelope

Like the gazelle, the Addax antelope is well known for its sleekness and its beauty. They are among the most endangered animals on the planet, with long, elegant horns and flat feet. Sadly they have been hunted to the point where there are only around 500 left. Global warming has also done them no favors. They are however very good at crossing the Sahara sands on their flat feet. They will probably not be able to adapt to human threats and global warming fast enough to survive however, and need our help.

3. The Scarab Beetle

Also known by the less dignifying (but perhaps more descriptive) name “dung beetle," the scarab beetle was a holy symbol to the ancient Egyptians and has some impressive adaptability. Dung beetles make creative use of animal feces. They are able to subsist almost entirely on animal waste. There are several ways that scarabs can make use of the dung they find, depending on how flexible they feel about their living situations. Dung beetles can roll dung until it makes a ball shape and then push it home, or simply dig a new burrow next to a heap of dung to live in. Some dung beetles just burrow into the dung they find and make it into a home, chewing their way out when they get hungry. Nom nom!

2. Dorcas Gazelle

Also known as the Ariel Gazelle, this animal is sleek and graceful, usually weighing around 25 kilograms. Many animals in the Sahara desert prey on gazelles, so the Dorcas gazelle has evolved to avoid them on impulse. When a predator approaches, the gazelle’s highly attuned body will automatically jump. This is known as “stotting." It serves several purposes. Firstly, it gets the gazelle out of immediate danger. Secondly, it demonstrates the gazelle’s speed and reflexes to the predator, discouraging it. Thirdly, it alerts other gazelles that a predator is approaching. If the gazelle is forced to run, it can achieve an astounding 49 miles per hour.

1. Camels

One animal you probably think about when you think about the desert is the Sahara desert camel. Camels store a large amount of fat in the humps on top of their backs (no, not water—that is a myth). The fat can be burned for energy when the camel is unable to locate any food. While most of us are searching for ways to burn off fat and slim up our bodies, camels are actually evolved by nature to carry extra fat around to survive!

The Sahara desert really is quite diverse, and as you can see, some of the most incredible species on the planet make their home there. The conditions may be daunting, but the animals that live there are up for the challenge. Even in difficult conditions, life can prevail, which is really quite inspiring. Next time you’re going through a rough patch, think about the animals of the Sahara and how you can learn from their example.

10 Fastest Animals On Earth

1. Peregrine Falcon

Birds have something of an advantage when it comes to speed, for obvious reasons. The peregrine falcon is particularly swift, capable of reaching speeds of up to 200 mph while at a dive, making it a fearsome hunter. The rest of the time it does not fly this fast, but that hardly matters to its prey. It is the fastest animal on the planet when in a dive.

2. Frigate Bird

This spectacular avian makes the peregrine falcon look slow by comparison. It can reach speeds of up to 95 miles per hour—much faster than you drive on the highway. It has the largest wingspan to body weight ratio and can stay in the air for intensely long periods. Sometimes these birds do not touch down for over week at a time. How’s that for speed and endurance?

3. Sail Fish

What is the fastest sea animal? That honor goes to the sail fish, which can read speeds up to 68 miles per hour—again possibly faster than you are used to driving on the highway. Can you imagine a fish racing alongside your vehicle and keeping up with you? That’s one fast sea animal. The characteristic sail is used when the fish is frightened in order to intimidate threatening animals. The rest of the time, it is kept folded up.

4. Cheetah

The fastest animal in the world is of course the cheetah. This animal is actually only slightly faster than the pronghorn antelope, and can reach speeds of up to 61 miles per hour. This record was set by an 11 year old cheetah in 2012 named Sarah. Unlike most of the other animals on this list, the cheetah is a predator. It represents a serious threat to animals on this list that inhabit the same geographic areas (not just grasslands, but forest environments as well).The cheetah is a sprinter, not a long distance runner, but pairs agility with speed for deadly attack runs. Cheetahs are also very fast accelerators, and can ramp up their speed four times faster than human beings can. They can also pull to a stop extremely fast. It is also interesting to note that the speed and agility of the cheetah is not matched by strength. The cheetah is fairly fragile and will lose in most fights with other predators. As a result, they will quickly surrender prey to competitors. An injured cheetah may not be able to run quickly, which can put its life in danger.

5. Pronghorn Antelope

This antelope takes second place among land animals for speed. It can easily out-sprint most predators at speeds as high as 60 miles per hour. Interestingly enough, a pronghorn antelope is not actually an old world antelope, and is native to North America. Actual antelopes are quite fast as well, but not as fast as the pronghorn. Also curious is the fact that the pronghorn is far faster than the predators which inhabit North America. This seems to indicate that it evolved its great speed at some point in the past under the threat of a now-extinct predator, perhaps the American cheetah.

The pronghorn has a number of special adaptations that allow it to function at high speeds, including cushioned, pointed toes to absorb shock, and extra large organs that assist with air intake

6. Blue Wildebeest

Another swift land animal which also inhabits the plains is the blue wildebeest. They are not quite as fast as the pronghorn, but are still pretty impressive at around 50 miles per hour.

7. Lion

Unfortunately for the blue wildebeest, the lion’s fastest speed almost exactly matches. Lions can chase down their prey at around 50 miles per hour, making them extremely deadly predators on the plains.

8. Thomson’s Gazelle

This is another creature in the same category as wildebeests and lions, also capable of running at around 50 miles per hour. Chases between lions and cheetahs and gazelles can be quite intense as a result of the close speed matching. Unfortunately for Thomson’s gazelles, they are the preferred prey of cheetahs, the fastest animal on our list.

9. Brown Hare

One of the smallest animals on our list is the brown hare. This little creature can run extremely fast, reaching speeds of up to 47 miles per hour. The story of the tortoise and the hare is famous for a reason. Hares really are incredibly fast creatures, and they are capable of outrunning the majority of other animals.

10. Elk

There are a number of animals which run faster than the elk, but the elk deserves a mention because it is a good deal larger and less “swift" looking than a gazelle or antelope. Elks can be quite large, but their size and build should not deceive you. The elk is capable of running at speeds as high as 45 miles per hour. Do not make an elk angry. If it charges you, it is going to win.

As you can see, there are some impressively fast animals on the land, as well as in the sea and air. These remarkable animals showcase the many different ways that creatures can adapt to fulfill the role of either predator or herbivore. While we may be at the top of the food chain thanks to our tools and inventions, we are easily outclassed when it comes to speed. Many of these creatures are as fast as the cars we have constructed to get from place to place at a reasonable pace. If that isn’t a humbling thought, what is?

14 of the Largest Animals in the World

The Largest Animal Ever: The Blue Whale

The blue whale (Balaenoptera musculus) is a marine mammal belonging to the suborder of baleen whales. At 30 metres (98 ft) in length and 180 metric tons (200 short tons) or more in weight, it is the largest known animal to have ever existed. The Blue Whale’s tongue weighs around 2.7 metric tons (5,952 pounds), about the size of an average Asian Elephant and its heart weighs about 600 kg (1,300 lb) and is the largest known in any animal. Not only is the heart similar size to a mini-cooper car but also comparable in weight. The Blue Whale is thought to feed almost exclusively on small, shrimp-like creatures called Krill. During the summer feeding season the Blue Whale gorges itself, consuming an astounding 3.6 metric tons (7,900 pounds) or more each day. This means it may eat up to 40 million krill a day with a daily calorie requirement of an adult Blue Whale in the region of 1.5 million.

The Heaviest Land Animal in the World: The African Bush Elephant

The African Bush Elephant is the largest living terrestrial (land) animal, with males reaching 6 to 7.5 metres (19.7 to 24.6 ft) in length, 3.3 metres (10.8 ft) in height at the shoulder, and weighing 6 t (13,000 lb). Females are much smaller, reaching 5.4 to 6.9 metres (17.7 to 22.6 ft) in length, 2.7 metres (8.9 ft) in height at the shoulder, and weighing 3 t (6,600 lb). The adult African bush elephant generally has no natural predators due to its great size, but the calves (especially the newborn) are vulnerable to lion and crocodile attacks, and (rarely) to leopard and hyena attacks.

The Tallest Land Animal in the World: The Giraffe

The giraffe (Giraffa camelopardalis) is an African even-toed ungulate mammal and the tallest living terrestrial animal in the world. It stands 5–6 m (16–20 ft) tall and has an average weight of 1,600 kg (3,500 lb) for males and 830 kg (1,800 lb) for females. The giraffe has an extremely elongated neck, which can be over 2 m (6 ft 7 in) in length, accounting for nearly half of the animal’s vertical height. The long neck results from a disproportionate lengthening of the cervical vertebrae, not from the addition of more vertebrae.

The Largest Carnivora in the World: The Southern Elephant Seal

The Southern elephant seal is the largest carnivore living today. This seals’ size shows extreme sexual dimorphism, possibly the largest of any mammal, with the males typically five to six times heavier than the females. While the females average 400 to 900 kilograms (880 to 2,000 lb) and 2.6 to 3 meters (8.5 to 9.8 ft) long, the bulls average 2,200 to 4,000 kilograms (4,900 to 8,800 lb) and 4.5 to 5.8 meters (15 to 19 ft) long. The record-sized bull, shot in Possession Bay, South Georgia on February 28, 1913, measured 6.85 meters (22.5 ft) long and was estimated to weigh 5,000 kilograms (11,000 lb). Southern elephant seals dive repeatedly, each time for more than twenty minutes, to hunt their prey—squid and fish— at depths of 400 to 1,000 meters (1,300 to 3,300 ft). The documented diving records for the seals are nearly two hours for the duration, and more than 1,400 meters (4,600 ft) in depth.The diverse order Carnivora includes over 280 species of placental mammals. Its members are formally referred to as carnivorans, while the word “carnivore” (often popularly applied to members of this group) can refer to any meat-eating organism. Carnivorans are the most diverse in size of any mammalian order, ranging from the least weasel (Mustela nivalis), at as little as 25 grams (0.88 oz) and 11 centimetres (4.3 in), to the polar bear and southern elephant seal. 

The Largest Land Carnivores in the World: The Polar Bear and Kodiak Bear

The largest living land carnivores are the Polar Bear (Ursus maritimus) and the kodiak bear, a Brown Bear (Ursus arctos) subspecies. Since they have similar body sizes, it is not clear which is definitively larger. In both species, shoulder height has been measured at more than 1.6 m (5.2 ft) and total length at as much as to 3.05 m (10.0 ft). The heaviest polar and brown bear weights recorded were respectively 1,003 kg (2,210 lb) and 1,135 kg (2,500 lb).

The Largest Reptile in the World: The Saltwater Crocodile

The saltwater crocodile (Crocodylus porosus), is the largest of all living reptiles. It is found in suitable habitats from Northern Australia through Southeast Asia to the eastern coast of India. An adult male saltwater crocodile’s weight is 409 to 1,000 kilograms (900–2,200 lb) and length is normally 4.1 to 5.5 metres (13–18 ft). However, mature males can exceed 6 metres (20 ft) and weigh more than 1,000 kilograms (2,200 lb) and this species is the only extant crocodilian to regularly reach or exceed 4.8 metres (16 ft). The saltwater crocodile is an opportunistic apex predator capable of taking nearly any animal that enters its territory, either in the water or on dry land

The Largest Amphibian in the World: The Chinese Giant Salamander

The Chinese giant salamander (Andrias davidianus) is the largest salamander in the world, reaching a length of 180 cm (6 ft), although it rarely – if ever – reaches that size today. Endemic to rocky mountain streams and lakes in China, it is considered critically endangered due to habitat loss, pollution, and over-collecting, as it is considered a delicacy and used in traditional Chinese medicine.

The Largest Rabbit/Hare in the World: The Flemish Giant

The Flemish Giant is an old breed of domesticated rabbits, originating from the Flemish region. They have been bred as early as the 16th century around the city of Ghent, Belgium. The rabbits can weigh up to 12.7 kg (28 pounds). 

The Largest Bats in the World: The Giant golden-crowned flying fox

The largest bat species is the Giant golden-crowned flying fox (Acerodon jubatus), an endangered fruit bat from the rainforests of the Philippines that is part of the megabat family. The maximum size is believed to approach 1.5 kg (3.3 lb), 55 cm (22 in) long, and the wingspan may be almost 1.8 m (5.9 ft). The Large Flying Fox (Pteropus vampyrus) is smaller in body mass and length, but it has been known to exceed the Golden-crowned species in wingspan. Specimens have been verified to 1.83 m (6.0 ft) and possibly up to 2 m (6.6 ft) in wingspan.

The Largest Rodent in the World: The Capybara

The largest living rodent is the capybara (Hydrochoerus hydrochaeris), native to most of the tropical and temperate parts of South America east of the Andes, always near water. Full-grown capybaras can reach 1.5 m (4.9 ft) long and 0.9 m (3.0 ft) tall at the shoulder and a maximum weight of 105.4 kg (232 lb). It is a highly social species and can be found in groups as large as 100 individuals, but usually live in groups of 10–20 individuals.

The Largest Bony Fish in the World: The Ocean Sunfish

Osteichthyes, also called bony fish, are a taxonomic group of fish that have bony, as opposed to cartilaginous, skeletons. The vast majority of fish are osteichthyes, which is an extremely diverse and abundant group consisting of over 29,000 species. It is the largest class of vertebrates in existence today. The largest living bony fish is the widely distributed ocean sunfish (Mola mola). It resembles a fish head with a tail, and its main body is flattened laterally. The mature ocean sunfish has an average length of 1.8 m (5.9 ft), a fin-to-fin length of 2.5 m (8.2 ft) and an average weight of 1,000 kg (2,200 lb), although individuals up to 3.3 m (10.8 ft) in length 4.2 m (14 ft) across the fins and weighing up to 2,300 kg (5,100 lb) have been observed.

The Largest Lizard/Snake in the World: The Green Anaconda

The most massive living member of this giant reptilian order is the Green Anaconda (Eunectes murinus) of the neotropical riverways. The maximum verified size is 7.5 m (25 ft) and 250 kg (550 lb), although rumors of larger anacondas persist. The Reticulated Python (Python reticulatus) of Southeast Asia is longer but more slender, and has been reported to measure as much as 9.7 m (32 ft) in length.

The Heaviest Flying Bird in the World: The Dalmatian Pelican

The Dalmatian Pelican (Pelecanus crispus) is a member of the pelican family. It breeds from southeastern Europe to India and China in swamps and shallow lakes. This is the largest of the pelicans, averaging 160–180 cm (63-70 inches) in length, 11–15 kg (24-33 lbs) in weight and just over 3 m (10 ft) in wingspan. With a mean weight of 11.5 kg (25 lb), it is the world’s heaviest flying bird species on average, although large male bustards and swans can exceed the pelican in maximum weight.

The Largest Arthropod in the World: The Japanese spider crab

The Japanese spider crab is a species of marine crab that lives in the waters around Japan. It has the largest leg span of any arthropod, reaching up to 3.8 metres (12 ft) and weighing up to 41 pounds (19 kg). In its natural habitat, the Japanese spider crab feeds on shellfish and animal carcasses and may live for up to 100 years.

 

 

 

9 most dangerous animals in the world

Mosquito

Moving from one of the largest animals in the world we now come to one of the smallest. As small as it is though, it is also the deadliest. It has been estimated that mosquitos transmit diseases to almost 700 million people annually resulting in 2 to 3 million deaths every year.

Blue Ringed Octopus

About the size of a golf ball, don’t let its small stature fool you, it holds enough venom to kill 26 full grown adults and as you may have guessed, there is no antidote. Assuming that your friend ever gets bitten you had better know CPR because you can be sure that within minutes they will be completely paralyzed and unable to breathe. Mother nature, however, shows no mercy and they will maintain their consciousness for the next few hours until the venom is neutralized by their body. This is of course assuming that you, or someone at the hospital, continues artificial respiration.

Tse Tse Fly

This large blood sucking fly is the primary carrier of African Sleeping Sickness and is therefore indirectly responsible for killing up to a quarter of a million people every year.

Carpet Viper

Responsible for the majority of snake related deaths in the world, this viper uses a hemotoxin similar to that of the boomslang. Unfortunately most of the bites occur in areas that lack modern medical facilitiesso the victims slowly bleed to death over the course of several weeks.

Brazilian Wandering Spider

Meet the most venomous spider in the world, according to the Guinness Book of World Records. What makes this critter so dangerous though is also how it got its name – a tendency to wander. They are often found hiding in houses and cars of densely populated areas, especially during daytime. Not a good combination.

Box Jellyfish

Killing more people every year than sharks, crocodiles, and stonefish combined, this box of death has been labeled “world’s most venomous animal.” Its venom is so potent in fact, that in some cases treatment consists of little more than last minute CPR.

Boomslang

Although they are relatively shy and don’t generally attack humans, when they do, things can get messy. Boomslang venom is a hemotoxin that disables blood clotting. In others words, its victims slowly die as they bleed out from every pore in their body.

Puffer Fish

Considered one of the most poisonous vertebrates in the world, if you have read our article about the   11 stranges foods in the world you know that it is a delicacy in Japan. Puffer poison will, however, paralyze your diaphragm and stop your breathing if you fail to prepare it correctly.

Poison Dart Fog

Packed into 2 inches of colorful amphibian is enough poison to kill an army of 20,000 mice. This means that with roughly 2 micrograms, or the amount that would fit on a pinhead, you could successfully stop the heart of a large animal. And to make matters worse, the poison is actually located on the surface of the skin. You seriously can’t touch this.
