Scorpion
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto ...

Scorpion Sting
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling. In serious cases, scorpion stings may involve the envenomation of humans by toxic scorpions, which may result in extreme pain, serious illness, or even death depending on the toxicity of the venom. Most scorpion stings range in severity from minor swelling to medically significant lesions, with only a few able to cause severe allergic, neurotic or necrotic reactions. However, scorpion stings account for approximately 3,000 deaths a year worldwide. The Brazilian yellow scorpion ('' Tityus serrulatus'') is one species known for being especially dangerous, being responsible for most scorpion sting fatalities in South America. Scorpion stings are seen all over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arachnid
Arachnida () is a class of joint-legged invertebrate animals (arthropods), in the subphylum Chelicerata. Arachnida includes, among others, spiders, scorpions, ticks, mites, pseudoscorpions, harvestmen, camel spiders, whip spiders and vinegaroons. Almost all adult arachnids have eight legs, although the front pair of legs in some species has converted to a sensory function, while in other species, different appendages can grow large enough to take on the appearance of extra pairs of legs. The term is derived from the Greek word (''aráchnē'', 'spider'), from the myth of the hubristic human weaver Arachne, who was turned into a spider. Almost all extant arachnids are terrestrial, living mainly on land. However, some inhabit freshwater environments and, with the exception of the pelagic zone, marine environments as well. They comprise over 100,000 named species, of which 47,000 are species of spiders. Morphology Almost all adult arachnids have eight legs, unlike adult i ...

Scorpius (constellation)
Scorpius is a zodiac constellation located in the Southern celestial hemisphere, where it sits near the center of the Milky Way, between Libra to the west and Sagittarius to the east. Scorpius is an ancient constellation that pre-dates the Greeks; it is one of the 48 constellations identified by the Greek astronomer Ptolemy in the second century. Its old astronomical symbol is (♏︎). Notable features Stars Scorpius contains many bright stars, including Antares (α Sco), "rival of Mars," so named because of its distinct reddish hue; β1 Sco (Graffias or Acrab), a triple star; δ Sco ( Dschubba, "the forehead"); θ Sco ( Sargas, of unknown origin); ν Sco (Jabbah); ξ Sco; π Sco (Fang); σ Sco (Alniyat); and τ Sco (Paikauhale). Marking the tip of the scorpion's curved tail are λ Sco ( Shaula) and υ Sco (Lesath), whose names both mean "sting." Given their proximity to one another, λ Sco and υ Sco are sometimes referred to as the Cat's Eyes. The constellat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orion (mythology)
In Greek mythology, Orion (; Ancient Greek: Ὠρίων or ; Latin: ''Orion'') was a giant huntsman whom Zeus (or perhaps Artemis) placed among the stars as the constellation of Orion. Ancient sources told several different stories about Orion; there are two major versions of his birth and several versions of his death. The most important recorded episodes are: his birth in Boeotia, his visit to Chios where he met Merope and raped her, being blinded by Merope's father, the recovery of his sight at Lemnos, his hunting with Artemis on Crete, his death by the bow of Artemis or the sting of the giant scorpion which became Scorpius, and his elevation to the heavens. Most ancient sources omit some of these episodes and several tell only one. These various incidents may originally have been independent, unrelated stories, and it is impossible to tell whether the omissions are simple brevity or represent a real disagreement. In Greek literature he first appears as a great hunter i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stinger
A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom, although not all stings are venomous. Bites, which can introduce saliva as well as additional pathogens and diseases, are often confused with stings, and vice versa. Specific components of venom are believed to give rise to an allergic reaction, which in turn produces skin lesions that may vary from a small itching weal, or slightly elevated area of the skin, to large areas of inflamed skin covered by vesicles and crusted lesions. Stinging insects produce a painful swelling of the skin, the severity of the lesion varying according to the location of the sting, the identity of the insect and the sensitivity of the subject. Many species of bees and wasps have two poison glands, one gland secreting a toxin in which formic acid is one r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpion Motif
Many motifs are used in traditional kilims, handmade flat-woven rugs, each with many variations. In Turkish Anatolia in particular, village women wove themes significant for their lives into their rugs, whether before marriage or during married life. Some motifs represent desires, such as for happiness and children; others, for protection against threats such as wolves (''to the flocks'') and scorpions, or against the evil eye. These motifs were often combined when woven into patterns on kilims. With the fading of tribal and village cultures in the 20th century, the meanings of kilim patterns have also faded. In these tribal societies, women wove kilims at different stages of their lives, choosing themes appropriate to their own circumstances. Some of the motifs used are widespread across Anatolia and sometimes across other regions of West Asia, but patterns vary between tribes and villages, and rugs often expressed personal and social meaning.

Fluorescent
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors ( fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detect ...

Predatory
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and inve ...

Viviparous
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients by oop ...

Kilim
A kilim ( az, Kilim کیلیم; tr, Kilim; tm, Kilim; fa, گلیم ''Gilīm'') is a flat tapestry- woven carpet or rug traditionally produced in countries of the former Persian Empire, including Iran, the Balkans and the Turkic countries. Kilims can be purely decorative or can function as prayer rugs. Modern kilims are popular floor coverings in Western households. Etymology The term 'kilim' originates from the Persian ''galīm'' (گلیم) where it means 'to spread roughly', perhaps of Akkadian or Aramean origin. another name for Galim(Gilim) is Plas, Ferdowsi and other persian poet mentioned both Galim and plas as synonyms in Shahnameh No 35 mentioned as Plas(pluNo14 mentioned as Gali History Like Pile weave, pile carpets, kilim have been produced since ancient times. The explorer Mark Aurel Stein found kilims dating to at least the fourth or fifth century CE in Hotan, China: :"As kilims are much less durable than rugs that have a pile to protect the warp and weft, i ...

Scorpio (astrology)
Scorpio () is the eighth astrological sign in the zodiac, originating from the constellation of Scorpius. It spans 210°–240° ecliptic longitude. Under the tropical zodiac (most commonly used in Western astrology), the Sun transits this sign on average from October 23 to November 21. Depending on which zodiac system one uses, someone born under the influence of Scorpio may be called a ''Scorpio'' or a ''Scorpionic''. Associations Scorpio is one of the water signs, the others being Cancer and Pisces. It is a fixed, negative sign. Scorpio is associated with three different animals: the scorpion, the snake, and the eagle. According to ''The Astrology Bible'', Scorpio's colors are deep red, maroon, black, and brown.
