Piranha

 

  

Animal State | Piranha | Piranhas are found in the Amazon basin, the Orinoco, in rivers of Guyana, Paraguay-Paraná and São Francisco River Systems. Piranhas were also found in the lake in southern Bangladesh Kaptai. Serrasalmus, Pristobrycon and Pygopristis Pygocentrus are the most easily recognized by their individual teeth. All piranhas have a single row of sharp teeth in the two jaws, the teeth are tight and locking (by means of small cusps) and are used for the rapid punching and shearing. Individual teeth are typically broadly triangular, sharp, blade-like (flat profile). There are minor variations in the number of cusps, in most species, the teeth are tricuspid with a longer median cusp which individual teeth appear substantially triangular. 

Piranhas are important ecological components of its natural environment. Although confined to the lower river, these fish are widespread and inhabit diverse lotic and lentic habitats. Some piranha species are abundant locally and multiple species often occur together. As both predators and scavengers, piranhas influence the local distribution and composition of fish assemblages. Some piranha species consume large quantities of seeds, but unlike the related Colossoma and Piaractus, herbivorous piranhas chew well and eat all the seeds completely consumed and therefore do not function as dispersers. Piranha has a reputation as fierce predators that hunt their prey in schools. Piranhas are "essentially as regular fish with big teeth." Research on the species Serrasalmus aff. 

Piranha teeth are often used to make tools and weapons by the indigenous population. Piranhas are also popular as food, but if an individual is bitch caught on a hook or line, can be attacked by another (free) piranhas Piranha are commonly consumed by subsistence fishermen and often sold for food in local markets in recent decades, the dried samples were marketed as tourist souvenirs. Piranhas occasionally bite and sometimes injure bathers and swimmers. A piranha bite is considered more an act of negligence of misfortune, but piranhas are a considerable nuisance to commercial and recreational fishers because they steal bait, mutilate catch, damage nets and other gear, and can bite when handled. Several piranha species appear in the aquarium trade. Piranhas can be bought as pets in some areas, but are illegal in many parts of the United States

The piranha aquarium is more common Pygocentrus nattereri, red-bellied piranhas. Piranhas can be bought at maturity or as babies, often no bigger than a thumbnail. Piranhas are likely to become cannibalistic on others in your group, if malnourished There are many myths about how they can piranhas dilacerate a human or bovine seconds. These myths refer specifically to Pygocentrus nattereri, red-bellied piranhas. Attacks on humans are usually reported around the docks where the fish are often torn and the viscera are usually thrown into the water. Piranha (1978) and Piranha II: The Spawning (1981) perpetuates the grim picture of piranha piranhas showing deadly bite and eat humans.

Armadillo

 

  

Animal State | Armadillo | Armadillos are prolific researchers with sharp claws. Many species use their sharp claws to dig for food such as larvae, and dig burrows. The nine tracks Armadillo prefers to build burrows in moist soil near streams, rivers and streams around which it lives and feeds. The diet of different armadillo species varies, but consists mainly of insects, worms and other invertebrates. Some species, however, feeds almost exclusively on ants and termites. In common with other xenarthrans, armadillos typically have low body temperature (33-36 ° C) and the basal metabolic rate (40-60% of that expected from a placental mammal of the mass). The armor is formed by plates of dermal bone covered in relatively small, overlapping epidermal scales called scutes ", composed of bone with a coating of the tube. The underside of the animal is not shielded, and is simply covered with the skin soft and skins. This skin armor seems to be the main defense of many armadillos, although most escape predators fleeing (often into thorny patches, from which their armor protects them) or digging to safety. Only the South American three bands armadillos (Tolypeutes) rely heavily on their armor. When threatened by a predator species often Tolypeutes rolling a ball. Other species of armadillo can not roll because they have other cards.

Armadillos have a very poor vision, and use your keen sense of smell to hunt They use their claws for digging and finding food and making their homes in burrows. Armadillo teeth of nine tracks is P 7/7, M 1/1 = 32. Gestation 60-120 days, depending on the species, although the armadillo nine-linked implant also delayed, so that the couple are generally not born to eight months after mating. Armadillos are solitary animals who do not share their burrows with other adults. Armadillos are often used in the study of leprosy, as they, with Mangabey monkeys, rabbits and mice (on their feet), are among the few known species of nonhuman animals that can contract the disease systemically. (Leprosy bacteria is difficult to culture and armadillo have a body temperature of 34 ° C (93 ° F), similar to human skin.) Humans can acquire an armadillo leprosy by handling or Armadillo eat meat. Because armadillos are native to the New World at some point they have acquired the disease in humans. The armadillo is also a natural reservoir of Chagas disease.

The nine-banded armadillo is also the science through its unusual reproductive system in which four children were born genetically identical, the result of an egg source. Armadillos (mainly Dasypus) make common roadkill due to their habit of jumping up mud when startled (such as an oncoming car).

Eagle

 

Animal State | Eagle | Eagles are large birds of prey and is powerful, with a heavy head and beak. Even the smallest eagles, like the eagle (which is comparable in size to a buzzard or red-tailed hawk), the wings are relatively longer and more uniformly broad and more direct, faster flight. Species listed as eagles vary in size from South Nicobar Serpent Eagle, 450 g (1 lb) and 40 cm (16 inches) to 6.7 kg (14.7 lbs) Sun Eagle Steller and 100 cm (39 inches) Filipino Eagle. Like all birds of prey, eagles have very large beaks hooks to tear the flesh of their prey, strong muscular legs and strong claws. The female of all known species of eagles are larger than males Eagles usually build their nests, called nests in tall trees or on cliffs.

 
Among the eagles are among the largest birds of prey: some of the condors and vultures of the Old World are bigger. Four species of Steller - Sea Eagle East Asia, South and Central American Harpy Eagle, the Philippine Eagle and Wedge-tailed Eagle of Australia - can reach one meter in length. The The size of both the Philippine eagle, the harpy eagle, and rarely more than two meters, increasing maneuverability through the forest where they live and the wedge-tailed eagle is relatively light, with an average mass of 3.466 g (7, 63 lbs) . [Citation needed] The Harpy Eagle and Wedge-tailed eagle is also shorter, measuring 89-100 cm and 80-104, respectively Steller's Sea Eagle is usually between 85-94 centimeters (33-37 inches). The modern English name of the bird is derived from the Latin word aigle eagle from the French. 

The Greek word can be a little old. The Albanian word for eagle is "shqiponje" comes from "Shqipe" root, meaning "eagle". In Britain before 1678, Eagle referred specifically the golden eagle, with other native species, the white-tailed eagle, being known as the Erne. The modern name "Golden Eagle" for Aquila chrysaetos was introduced by the naturalist John Ray. The Moche people of ancient Peru worshiped animals and often depicted eagles in their art. Despite these modern and historic Native American practices of giving eagle feathers to non-Indians and members of other tribes that have been deemed worthy, current United States eagle feather law stipulates that only individuals of certifiable Native American ancestry enrolled in a federally recognized tribe are legally authorized to obtain eagle feathers for religious or spiritual. The eagle is also the patron saint of animals of Zeus.
