The world of wildlife is often depicted in vivid colors. However, there are also animals that have a monotonous and darker appearance when there is only one black color on the body. Join Toplist to learn about the most mysterious black animals.
American black bear
The North American black bear (Ursus americanus) is a medium-sized bear native to North America. It is the continent's smallest and most common bear species. North American black bears are omnivores with diets that vary considerably depending on the season and location. They usually live in predominantly forested areas, but leave the forest in search of food. They sometimes infiltrate communities because of the availability of food for them. Black bears often mark trees using their teeth and claws as a form of communication with other bears, a behavior common to many bear species.
The North American black bear is the most common bear species in the world. It is listed as a species of least concern by the IUCN, due to its widespread prevalence and large global population estimated at twice that of all other bear species combined. Along with the brown bear, it is one of only two of eight modern bear species that are not considered globally threatened with extinction as assessed by the IUCN. Today, the population of black bears in the Americas is estimated at between 850,000 and 950,000 individuals.
The black bear's coat is soft, with a dense inner coat and large, long, coarse guard coat. The hairs are not as rough or coarse as that of brown bears. The North American black bear's coat is distinct from the black bear's in that it lacks a white space under the chin and stiff hair on the paws. Despite the name, the black bear's fur comes in a wide variety of colors. Coat color can range from white, yellow, cinnamon, or light brown to dark chocolate brown, or jet black, with many intermediate variations existing. Individuals with albinism have also been recorded.
About 80% of all black bears are black, although only 50% of black bears in the Rocky Mountains are black. Black bears that live along the coasts of Alaska and British Columbia have bluish fur. Black bears with white to cream fur are found on the coastal islands and adjacent mainland southwest of British Columbia. The black coat tends to prevail in wet areas such as New England, New York, Tennessee, Michigan and western Washington.
Black Panther
The black panther or black leopard, also known as the leopard, is a genetic variation that occurs in several species of big cats. These individuals are black because they carry mutations in genes related to melanin metabolism. This variation will probably give some selective advantage to individuals living in areas with dense forest density, very low light levels. It is not a separate species as there is no mating isolation from other groups. In a litter of a pair of leopards, normal parents can produce mutant carriers and non-carriers. This variation is common in jaguars (Panthera onca) and leopards (Panthera pardus).
Black panthers are omnivores although they are carnivores and actively hunt. Like leopards, they always take advantage of opportunities, eating anything they can find, including rotting meat and livestock and domestic animals.
They can kill animals 2-4 times their own weight, such as Bharal sheep, Himalayan shorthorn goats, markhor goats, Argali sheep, horses and camels, but are also willing to eat small prey. much more, such as hares, marmota, pika, and voles and birds.
The black panther's diet varies across its range and with the time of year, and is dependent on prey availability. In the Himalayas, they hunt mainly Bharal sheep and Siberian mountain goats. In the Karakoram, Tian Shan, Altai and Tost Mountains of Mongolia, its main prey includes Siberian mountain goats, white-lipped deer, Siberian roe deer and Argali sheep. Other species that may be hunted by them when the opportunity arises are the red panda, wild boar, langur and Chukar partridge.
American crow
The American crow is a common crow in much of the United States and Canada. As an adult, this bird is completely black from beak to tail, with the exception of brown eyes. Crows are said to be one of the most intelligent birds and can live in a wide variety of environments.
The American crow (Corvus brachyrhynchos) is a species of bird in the Crow family. This crow is widely distributed in North America. From beak to tail, an American crow measures 40–50 cm long, almost half the length of the tail. Weight varies from about 300 to 600 g (11 to 21 oz). Males tend to be larger than females.
American crows are omnivores. They feed on invertebrates, carcasses, human leftovers, seeds, eggs and chicks, fish stranded on the shore, and various grains. American crows are active hunters and hunt for mice, frogs, and other small animals. During the winter and fall, the American crow's diet relies more on nuts and acorns. Occasionally, they hang out with bird feeders.
The American crow is one of the few birds that has been observed to modify and use tools to obtain food. Like most crows, they scavenge for food in landfills, scattering litter in the process. If available, corn, wheat and other crops are a favorite food. These habits have historically caused the American crow to be seen as a nuisance. However, it is doubtful that the crop damage is offset by the service the American crow provides by eating harmful insects.
Black Wolf
Black wolves occur mostly in North America, Europe and some parts of Asia. This animal possesses a pair of sparkling amber eyes.
Black wolves or black wolves are mutant wolves with black pigmented fur and black fur. In fact, the black wolf is the gray wolf (Canis lupus). The black wolf was one of the first genetically engineered predators. Black wolves are reflected in many novels, movies, and comics as special individuals in the wolf pack. Common werewolf images are wolves with black fur.
The common coat color of gray wolves is white and gray, but among them there are a few that have a very special black coat. In fact, this is not their natural color. A 2008 Stanford University study found that a particular set of genes for black coat color only occurs in dogs, so the black wolf appears to be the result of crossbreeding. The gene for the black color of this coat is dominant, so it is passed on to most offspring. Although black wolves do not appear to be excellent hunters, they do have a better immune system. The black wolf is almost exclusively found in the cold regions of North America.
The black wolf is actually a wolf-dog hybridisation. In an unusual evolutionary event, dogs that mated with wolves thousands of years ago passed on a genetic mutation that codes for black coat color to the wolves' ancestors. As a result, gray wolves or no longer have gray fur. The dogs of the first Native Americans, contributed to the genetic diversity of their wild relatives in a way that affected both the appearance and survival of the mutant. variable. Wolves and domestic dogs share the same genetic pathway that determines black coat color. Black wolves will turn gray in old age.
black Swan
The Black Swan (Cygnus atratus) is a species of bird in the subgenus Chenopis in the swan genus, the Duck family. This species is native to Australia, it was hunted to the point of extinction but was later introduced to New Zealand. This species mainly breeds in southeastern and southwestern Australia. In Australia, they are nomadic depending on climatic conditions. Its plumage is almost black with a red bill.
This species was scientifically described by Australian naturalist John Latham in 1790, formerly placed in the monotypic genus Chenopis. It is a solitary species or lives in loose flocks with numbers of hundreds to thousands. An adult black swan measures between 110 and 142 cm (43 and 56 in) in length and weighs 3.7–9 kilograms (8.2–19.8 lb). The wingspan is 1.6 to 2 meters (5.2 and 6.6 ft) long. The neck is long (relatively the longest of any swan) and has an "S" curve.
Beautiful and graceful in appearance, black swans commonly inhabit the wetlands of South West and Eastern Australia, and throughout Tasmania. The bright red beak of the black swan provides a striking contrast to the animal's jet-black plumage.
The black swan has a subgenus, the New Zealand swan, Cygnus (atratus) sumnerensis, an extinct subspecies of the black swan from New Zealand and from the Chatham Islands.
Black carpenter ant
Distinguished from other carpenter ants by the dull black color of the head and body, black carpenter ants also possess a formidable set of teeth that can bite very hard. This animal is native to central and eastern America as well as eastern Canada.
Their abdomens are large, round and filled with transparent golden drops of honey. Black carpenter ants organize society according to floors and levels. The highest position in the colony belongs to the queen ant, taking on the reproductive role. However, in an ant colony, some are male ants who are responsible for coordinating with the queen to create new generations. The rest are worker ants and a small part are honey ants. The task of black carpenter ants is to gain weight, they are as large as possible, they rarely move, they always quietly hang themselves on the roof of the nest and only move when absolutely necessary. The big belly of these honey ants actually contains a lot of nutrients in liquid form. They act as food storage cabinets for the whole nest.
Black carpenter ants bring food to their fellow humans, honey ants' bellies can reach the size of a large grape. In times of food scarcity, black carpenter ants will be responsible for providing nutrition to other members of the nest. At that time, the worker ants will simply pull the antennae of the black carpenter ant and they will enjoy the nutritious vomit released by the honey ants. Some subspecies of black carpenter ants in Australia have the habit of eating this mobile food storage, the honey ants will be torn apart, eaten by their own kind. They will then spit out a portion of the meal and use that to nourish their fat-bellied ants.
Chicken Ayam Cemani
The Ayam Cemani chicken is considered one of the rarest chickens in the world, because of its unique characteristics. The dominant black color is the most magical thing this chicken has.
The Ayam Cemani is a breed of chicken native to Indonesia. This breed is famous because everything in their body, from blood, tongue to crest, is black. In Vietnam, they are used to calling this chicken breed the devil-faced chicken because they are black, so they look very scary. The Ayam Cemani is also considered the most expensive chicken breed in the world[5]. According to Business Insider, at Greenfire Farm in Florida, the selling price of an Ayam Cemani chicken is about $2,500 (about VND 52 million).
Ayam cemani chicken breed originated from Java, Indonesia. In 1998, the breed was introduced to Europe. The appearance of chicken Ayam Cemani has attracted the attention of many experts in genetic research. According to experts, the characteristic black color of this type of chicken is due to a genetic trait called fibromelanosis, which promotes the growth of cells that carry the black pigment. The gene that causes fibromelanosis is a mutated gene. Studies have shown that genetic mutations can cause chickens to have a variety of strange traits.
Since the Dutch brought this breed to Europe, the cemani has been bred in a number of other countries such as the UK, Poland and some other countries in very limited numbers. set chickens in the US of special interest. The speciality of the cemani chicken not only interests chicken lovers and breeders around the world, but even in its homeland in Indonesia it is still considered a rare breed with outstanding value compared to other species. other chickens. Due to the high demand of collectors and breeders, the price of Cemani chickens is constantly increasing and has become one of the most expensive chicken breeds in the world.
Oriental indigo snake
This oriental indigo snake deserves to be ranked in the list of the most beautiful snakes in the world, because of the jet black color on their body. The Oriental indigo snake was discovered in Texas, USA, and is commonly known as the longest snake in the Americas (with an average length of more than 3 meters in adults). This snake is not venomous and often has to work very hard to kill its prey.
The Oriental indigo snake is a non-venomous, non-venomous black common snake that is the longest native snake in North America. The Oriental indigo snake (Drymarchon couperi) is the largest native snake in the United States. Adults can be up to 2.8m long and weigh from 2.5 to 5kg. They are members of the family of water snakes, living mainly in tree-lined areas and near water sources in the southeastern United States.
The diet of the oriental indigo snake is very diverse. They eat any small animal that can be caught from turtles, frogs, lizards, birds, mammals to some other venomous snakes such as rattlesnakes thanks to their immunity to venom. poison.
Oriental indigo snakes have very few natural enemies. Humans are the biggest threat to them. Over-hunting and habitat destruction are the main reasons for the drastic decline in the population of this species.
Oriental indigo snake is the longest snake in America, approximately 3 m and most beautiful because of the jet black color on their body. Although not venomous, they are very aggressive. They also attack other venomous snakes such as the Texas rattlesnake and are completely immune to its venom.
Black squirrel
Black squirrels occur largely throughout North America and Great Britain. The distinctive appearance of this animal is due to a cross between a gray squirrel and an eastern fox squirrel. Black coat color can occur naturally as a mutation in gray squirrel populations, but it is very rare. The rarity of the black squirrel has made many people admire and love them, and the black squirrels enjoy public affection and in some places people consider them as mascots. In some US states, as well as in Canada and the UK, black squirrels have been introduced into the wild in the hope of increasing their numbers, but this also poses a risk to native squirrel species.
A rare mutation of both the eastern gray squirrel and the fox squirrel, the black squirrel can survive anywhere a gray squirrel or fox squirrel is present. Among eastern gray squirrels, gray mating pairs cannot produce black males. Gray squirrels have two copies of a common pigment gene and black squirrels have one or two copies of a mutated pigment gene.
If a black squirrel has two copies of the mutated gene, it will be black. If it has one copy of the mutated gene and one normal gene it will be dark brown. In areas with high concentrations of black squirrels, litters of mixed-colored individuals are common. The black subgroup seems to have prevailed throughout North America before the arrival of Europeans in the 16th century, when the old American forests were still numerous and dense. The squirrel's dark color helps them hide in these dense, old forests.
As time went on, deforestation and hunting of squirrels for their favorite meat and tubers led to biological benefits for the grays; Their light gray color becomes favorable in their new and changing habitat. Today, the black subgroup is especially abundant in the northern part of the eastern Siberian strip. This is due to two main factors. First, black squirrels are significantly more cold tolerant than gray squirrels. Second, because the northern forests are denser and therefore darker, the black squirrel prefers to take advantage of better concealment in this dim habitat.
Short pilot whale
The genus Pilot whale (scientific name: Globicephala) is a genus of the oceanic dolphin family. This genus has two extant species. These two species are not easily distinguished at sea and analysis of the skull is the best way to tell the difference between them. Between the two species, pilot whales have a near-seas range with cold-water longfin pilot whales and short-finned pilot whales living in tropical and subtropical waters worldwide. . Pilot whales are one of the largest dolphin species, the size of which is surpassed only by killer whales.
Short pilot whales have black to dark gray skin. Short-finned pilot whales have short flippers and live mainly in warm tropical and subtropical waters.
Pilot whales mainly eat squid, but also fish. They are highly social, and research suggests that both males and females remain in the maternal group, an unusual trait among mammals, also found in some reptile whale communities. player. The shortfin pilot whale is also one of the few mammals where women go through menopause.
Black Widow Spider
The black widow spider is one of the most venomous spiders in the world. The crimson hourglass mark on the underside of the abdomen is the only contrast to the jet-black color of this animal.
The black widow spider is a genus of spiders in the family Theridiidae, of which 31 species are recognized. Widow spider is the common name that is sometimes applied to members of the genus due to the behavior of females eating males after mating, although sometimes males of some species do not eat after mating. and possibly to fertilize other offspring. Black widow spiders are perhaps the most famous members of this genus. The latrotoxin from the bite of this species is a relatively potent neurotoxin that is harmful to humans because of its unusually large venom glands, however, the Latrodectus bite rarely kills humans if the wound is they receive medical treatment.
According to the publication published in the Times of India, researchers at the University of Hamburg in Germany discovered that male spiders sacrifice to provide good health for their offspring. However, the results of the study by Blackledge, et al. disagree with this opinion. Silk from the black widow spider is famous for its toughness compared to the silk of other spiders.
Female "black widow" spiders are the terror of male mates, because they have a preference for "eating" their mates after each mating. However, cannibalism will not take place if they are well fed.
Longhorn Cactus Bug
These glossy black bugs, also known as Moneilema are known for their long antennae and the fact that they cannot fly. This is because their front wings have fused and cannot be opened. Adults are half an inch to 1.3 inches long.
Found in the deserts of Mexico and the United States, this beetle feeds on cacti, especially saguaro, prickly pear, and cholla. Although the adults feed on the treetops, they can also bore into the roots of cactus and possibly kill the plant. Adults emerge in May or June and continue to feed until the end of September. They will protect themselves from the heat of the desert by hiding on the lower parts of the cactus. The female lays her eggs in a spot on the cactus where the bark has been punctured by her, sometimes burrowing inside and even pupating inside the plant.
Like many other flightless beetles, these beetles have limited wing muscles with a rounded abdomen and thorax, superficially similar to some other flightless desert beetles. The cactus longhorn beetle looks and behaves like the noxious bugs in the genus Eleodes.
