The NAZCA Lines

The Nazca lines

​

The Nazca Lines are a series of geoglyphs located in the Nazca Desert, a high arid plateau that stretches more than 80 km (50 miles) between the towns of Nazca and Palpa on the Pampas de Jumana in Peru. Although some local geoglyphs resemble Paracas motifs, these are largely believed to have been created by the Nazca culture between 200 BCE and 700 CE. There are hundreds of individual figures, ranging in complexity from simple lines to stylized hummingbirds, spiders, monkeys, fish, sharks or orcas, llamas, and lizards.

The lines are shallow designs in the ground where the reddish pebbles that cover the surrounding landscape have been removed, revealing the whitish earth underneath. Hundreds are simple lines or geometric shapes, and more than seventy are natural or human figures. The largest are over 200 m across. Scholars differ in interpreting what the lines were for but generally ascribe religious significance to them. "The geometric ones could indicate the flow of water or be connected to rituals to summon water. The spiders, birds, and plants could be fertility symbols. Other possible explanations include: irrigation schemes, giant astronomical calendars, or landing for spaceships."

The dry, windless, stable climate of the plateau has preserved the lines to this day, for the most part. Extremely rare changes in weather may temporarily alter the general designs.

​

One explanation for the method of construction employed by the Nazca people involves the use of simple tools and surveying equipment. Wooden stakes in the ground at the end of some lines (one of which was found and used to carbon-date all of the figures) support this theory. Researcher Joe Nickell of the University of Kentucky has reproduced the figures using the technology available to the Nazca people of the time and without aerial assistance. With careful planning and simple technologies, a small team of individuals could recreate even the largest figures within days.

The lines were made by removing the reddish-brown iron oxide-coated pebbles that cover the surface of the Nazca desert. When the gravel is removed, the lines contrast sharply with the light-colored earth beneath. There are several hundred simple lines and geometric patterns on the Nazca plateau, as well as over seventy curvilinear animal and human figures. The area encompassing the lines is nearly 500 square kilometers (193 square miles), and the largest figures can be nearly 270 m long (886 feet). The lines persist due to the extremely dry, windless, and constant climate of the Nazca region. The Nazca desert is one of the driest on Earth and maintains a temperature around 25°C (77°F) all year round, and the lack of wind has helped keep the lines uncovered to the present day.

Tooth "BLING" in Ancient South- America

Tooth jewelry.

In hip hop culture, a grill (also front or golds) is a type of jewelry worn over the teeth. Grills are made of metal and are generally removable. They began to be worn by hip hop artists in the early 1980s, but they became widely popular during the mid-2000s due to the rise of Dirty South rap. Though grills are fitted to the tooth impression of the wearer, whether they are safe for long-term wear is unknown.

Grills are made of metal (often silver, gold, or platinum) that is sometimes inlaid with precious stones; they are generally removable, though some may be permanently attached to the teeth. Grills can cost anywhere from fifty dollars to thousands of dollars, depending on the materials used and the number of teeth covered.

Grills are most often worn by 18- to 35-year-old urban male hip-hop listeners, and at least one commentator has argued that grills will never become mainstream. However, grills are worn by both men and women of all races, at least to some extent, as well as by celebrities far from hip-hop culture like Marilyn Manson or Travis Barker of Blink-182.

Paul Karason (The BLUE MAN)

Argyria is a condition caused by improper exposure to chemical forms of the element silver, silver dust or silver compounds. The most dramatic symptom of argyria is that the skin becomes blue or bluish-grey colored. Argyria may be found as generalized argyria or local argyria. Argyrosis is the corresponding condition related to the eye. The condition is believed to be permanent, but laser therapy has been used to treat it with satisfactory cosmetic results.

Since at least the early part of the 20th century, doctors have known that silver or silver compounds can cause some areas of the skin and other body tissues to turn gray or blue-gray. Argyria occurs in people who eat or breathe in silver over a long period (several months to many years). A single exposure to a silver compound may also cause silver to be deposited in the skin and in other parts of the body; however, this is not known to be harmful. It is likely that many exposures to silver are necessary to develop argyria. Once argyria develops, it is generally believed to be permanent.

The Cantor's GIANT SOFT-SHELLED Turtle

The Cantor's giant soft-shelled turtle (Pelochelys cantorii) is a species of fresh water turtle. The turtle has a broad head and small eyes close to the tip of its snout. The carapace is smooth and olive colored. Juveniles may have dark-spotted carapaces and heads, with yellow around the carapace.

Cantor's giant soft-shelled turtles can grow up to 6 feet (about 2 meters) in length. P. cantorii is an ambush predator and primarily carnivorous, feeding on crustaceans, mollusks and fish (although some aquatic plants may also be eaten).

The turtle spends 95 percent of its life buried and motionless, with only its eyes and mouth protruding from the sand. It surfaces only twice a day to take a breath, and lays 20-28 eggs (about 1.2 to 1.4 inches [3.0-3.5cm] in diameter) in February or March on riverbanks.


Distribution
The turtle is found primarily in inland, slow-moving fresh water rivers and streams. There is some evidence that its range extends to coastal areas as well.

The turtle was once distributed across India, Bangladesh, Burma, Thailand, Malaysia, Cambodia, Vietnam, China, the Philippines, Indonesia, Papua New Guinea, Sumatra, Borneo, and western Java.

The turtle is regarded as endangered, and has disappeared from much of its range. Until recently, it was last seen in Cambodia in 2003. A 2007 survey of one area of the Mekong River in Cambodia found the turtle in abundance along a short 30-mile (48 kilometer) stretch of the river.

The species is not found in New Guinea, while the two other members of the genus Pelochelys, P. bibroni and P. signifera are both restricted to New Guinea.

P. cantorii is relatively unstudied, and it is possible that the current species may actually be composed of several taxa. One recent scholarly study showed that what was once thought to be P. cantorii in New Guinea was actually Pelochelys bibroni, and that earlier studies of P. cantorii only described populations further to the west.

Despite reports that it can grow up to 1.8 metres (5.9 ft) in length and is the world's largest extant freshwater turtle, this maximum size and title is murky at best.  Apparently the largest specimen carapace length, 129 cm (51 in), known is considered suspect and the heaviest specimen known (weighing approximately 250 kg (550 lb) was actually a misidentified Yangtze giant softshell turtle. A more realistic range of carapace length for this species is reportedly 70 to 100 cm (28 to 39 in) and it is one of about a half-dozen giant softshell turtles from three genera that reach exceptionally large sizes, i.e. in excess of 100 kg (220 lb) in mass.

The STAR NOSED Mole

The star-nosed mole (Condylura cristata) is a little North American mole found in wet low areas of eastern Canada and the north-eastern United States, with records extending along the Atlantic coast as far as extreme southeastern Georgia. It is the only member of the tribe Condylurini and the genus Condylura.

Star-nosed moles are easily identified by the eleven pairs of pink fleshy appendages ringing their snout which are used as a touch organ with more than 25,000 minute sensory receptors, known as Eimer’s organs, with which this hamster-sized mole feels its way around.


Appearance and Behavior

The star-nosed mole lives in wet lowland areas and eats small invertebrates, aquatic insects, worms and mollusks. It is a good swimmer and can forage along the bottoms of streams and ponds. Like other moles, this animal digs shallow surface tunnels for foraging; often, these tunnels exit underwater. It is active day and night and remains active in winter, when it has been observed tunnelling through the snow and swimming in ice-covered streams. Little is known about the social behavior of the species, but it is suspected that it is colonial.

The star-nosed mole is covered in thick blackish brown water-repellent fur and has large scaled feet and a long thick tail, which appears to function as a fat storage reserve for the spring breeding season. Adults are 15 to 20 cm in length, weigh about 55 g, and have 44 teeth. The mole's most distinctive feature is a circle of 22 mobile, pink, fleshy tentacles at the end of the snout, from which they derive their name. These are used to identify food by touch, such as worms, insects and crustaceans.

The star-nosed mole mates in late winter or early spring, and the female has one litter of typically 4 or 5 young in late spring or early summer. However, females are known to have a second litter if their first is unsuccessful. At birth, each offspring is about 5 cm long, hairless, and weighs about 1.5g. Their eyes, ears, and star are all sealed, only opening and becoming useful approximately 14 days after birth. They become independent after about 30 days, and are fully mature after 10 months. Predators include the Red-tailed Hawk, Great Horned Owl, various skunks and mustelids, and even large fish.

The incredibly sensitive nasal tentacles are covered with minute touch receptors known as Eimer's organs. The nose is approximately one centimeter in diameter with approximately 25,000 Eimer's organs distributed on 22 appendages. Eimer's organs were first described in the European mole in 1871 by German zoologist Theodor Eimer. Other mole species also possess Eimer's organs, though they are not as specialized or numerous as in the star-nosed mole. Because the star-nosed mole is functionally blind, it had long been suspected that the snout was used to detect electrical activity in prey animals,though there is little, if any, empirical support for this contention. It appears the nasal star and dentition of this species are primarily adapted to exploit extremely small prey items. A report in the journal Nature gives this animal the title of fastest-eating mammal, taking as short as 120 milliseconds (average: 227 milliseconds) to identify and consume individual food items. Its brain decides in the ultra short time of 8 ms if a prey is comestible or not. This speed is at the limit of the speed of neurons.
They also possess the ability to smell underwater. It is done by exhaling air bubbles onto objects or scent trails and then inhaling the bubbles to carry scents back through the nose.
