A trident is a three-pronged spear. It is used for spear fishing and as a polearm; the trident is Neptune, the God of the Sea in classical mythology. The trident may be held by other marine divinities such as Tritons in classical art, trident maybe depicted in medieval heraldry as well, sometimes held by a merman-Triton. In Hinduism, it is the weapon of Shiva, known as trishula; the word "trident" comes from the French word trident, which in turn comes from the Latin word tridens or tridentis: tri meaning "three" and dentes meaning "teeth", referring to the three prongs, or "teeth", of the weapon. The Greek equivalent is τρίαινα, from Proto-Greek trianja, meaning "threefold"; the Greek term does not imply three of anything specific, is vague about the shape, thus the assumption it was of "trident" form has been challenged. Latin fuscina means "trident"; the Sanskrit name for the trident, trishula, is a compound of tri त्रि for "three" and ṣūla शूल for "thorn", calling the trident's three prongs "thorns" rather than "teeth".

The trident is associated with his Roman counterpart Neptune. This divine instrument is said to have been forged by the cyclopes. Poseidon struck a rock with his trident, and according to Roman sources, Neptune struck the earth with the trident to produce the first war-horse. Poseidon, as well as being the god of the sea, was known as the "Earth Shaker", believed to cause earthquakes. In the Renaissance artist Gian Bernini's sculpture Neptune and Triton, Neptune is posed holding a triton turned downwards, is thought to reenact a scene from Aeneid or Ovid's Metamorphosis where he is calming the waves to aid Aeneas's ships. In Greek and Roman art and literature, other sea deities and their attendants have been depicted holding the trident. Poseidon's consort Amphitrite is identified by some marine attribute other than a trident, which she never carries according to some scholars, though other commentators have disagreed. Turning to the retinue or a train of beings which follow the sea deities the Tritons may be seen bearing tridents.

And Old Man of the Sea and the god Nereus which are mermen are seen holding tridents. The Tritons and the other mermen and the Nereides can carry rudders, fish, or dolphins. Oceanus should not carry a trident, allowing him to be distinguished from Poseidon. However, there is conflation of the deities in Romano-British iconography, examples exist where the crab-claw headed Oceanus bears a trident. Oceanus holding a trident has been found on Romano-British coinage as well; some amorini have been depicted carrying tiny tridents. The trident is seen suspended like a pendant on a dolphin in Roman mosaic art. In Hindu legends and stories Shiva, the Hindu god who holds a trishula trident in his hand, uses this sacred weapon to fight off negativity in the form of evil villains; the trident is said to represent three gunas mentioned in Indian vedic philosophy namely sāttvika, rājasika, tāmasika. A weapon of South-East Asian depiction of Hanuman, a character of Ramayana. In religious Taoism, the trident represents the Three Pure Ones.

In Taoist rituals, a trident bell is used to invite the presence of deities and summon spirits, as the trident signifies the highest authority of Heaven. A fork Jewish priests used to take their portions of offerings. In Ancient Greece, the trident was employed as a harpoon for spearing large fish tunny-fishing. In Ancient Rome tridents were used by a type of gladiator called a retiarius or "net fighter"; the retiarius was traditionally pitted against a secutor, cast a net to wrap his adversary and used the trident to kill him. In heraldry within the UK, the trident is held by the figure identified as either a Neptune or a triton, or a merman; the trident held up by an arm is depicted on some coats-of-arms. Spear-fishingTridents used in modern spear-fishing have barbed tines, which trap the speared fish firmly. In the Southern and Midwestern United States, gigging is used for harvesting suckers, bullfrogs and many species of rough fish. AgricultureIt has been used by farmers as a decorticator to remove leaves and buds from the stalks of plants such as flax and hemp.

The glyph or sigil of the planet Neptune, which alludes to the trident, is used in astronomy and astrology; the Tryzub in the Coat of Arms of Ukraine, adopted in 1918 The national emblem on the flag of Barbados. The "forks of the people's anger", adopted by the Russian anti-Soviet revolutionary organization, National Alliance of Russian Solidarists.

The symbol for Washington and Lee University; the symbol for the athletic teams at the University of Missouri–St. Louis. Sparky the Sun Devil, the mascot of Arizona State University, holds a trident; the trident was used as original logo for the Seattle Mariners. An element on the flag of the Sea Shephe

The Australian magpie is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is placed in its own genus Gymnorhina and is most related to the black butcherbird, it is not, however related to the European magpie, a corvid. The adult Australian magpie is a robust bird ranging from 37 to 43 cm in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill; the male and female are similar in appearance, can be distinguished by differences in back markings. The male has pure white feathers on the back of the head and the female has white blending to grey feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground. Described as one of Australia's most accomplished songbirds, the Australian magpie has an array of complex vocalisations.

It is omnivorous, with the bulk of its varied diet made up of invertebrates. It is sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks and farmland in Australia and New Guinea; this species is fed by households around the country, but in spring a small minority of breeding magpies become aggressive and swoop and attack those who approach their nests. Over 1000 Australian magpies were introduced into New Zealand from 1864 to 1874 but have subsequently been accused of displacing native birds and are now treated as a pest species. Introductions occurred in the Solomon Islands and Fiji, where the birds are not considered an invasive species; the Australian magpie is the mascot of several Australian sporting teams, most notably the Collingwood Magpies, the Western Suburbs Magpies and Port Adelaide Magpies. The Australian magpie was first described by English ornithologist John Latham in 1801 as Coracias tibicen, the type collected in the Port Jackson region.

Its specific epithet derived from the Latin tibicen "flute-player" or "piper" in reference to the bird's melodious call. An early recorded vernacular name is piping poller, written on a painting by Thomas Watling, one of a group known collectively as the Port Jackson Painter, sometime between 1788 and 1792. Other names used include piping crow-shrike, maggie, flute-bird and organ-bird; the term bell-magpie was proposed to help distinguish it from the European magpie but failed to gain wide acceptance. Tarra-won-nang, or djarrawunang and marriyang were names used by the local Eora and Darug inhabitants of the Sydney Basin. Booroogong and garoogong were Wiradjuri words, carrak was a Jardwadjali term from Victoria. Among the Kamilaroi, it is galalu, or guluu. In Western Australia it is known as warndurla among the Yindjibarndi people of the central and western Pilbara, koorlbardi amongst the south west Noongar peoples; the bird was named for its similarity in colouration to the European magpie. However, the European magpie is a member of the Corvidae, while its Australian counterpart is placed in the family Artamidae.

The Australian magpie's affinities with butcherbirds and currawongs were recognised early on and the three genera were placed in the family Cracticidae in 1914 by John Albert Leach after he had studied their musculature. American ornithologists Charles Sibley and Jon Ahlquist recognised the close relationship between woodswallows and the butcherbirds in 1985, combined them into a Cracticini clade, in the Artamidae; the Australian magpie is placed in its own monotypic genus Gymnorhina, introduced by the English zoologist George Robert Gray in 1840. The name of the genus is from the Ancient Greek gumnos for "naked" or "bare" and rhis, rhinos "nostrils"; some authorities such as Glen Storr in 1952 and Leslie Christidis and Walter Boles in their 2008 checklist, have placed the Australian magpie in the butcherbird genus Cracticus, arguing that its adaptation to ground-living is not enough to consider it a separate genus. A molecular genetic study published in a 2013 showed that the Australian magpie is a sister taxon to the black butcherbird and that the two species are in turn sister to a clade that includes the other butcherbirds in the genus Cracticus.

The ancestor to the two species is thought to have split from the other butcherbirds between 8.3 and 4.2 million years ago, during the late Miocene to early Pliocene, while the two species themselves diverged sometime during the Pliocene. The Australian magpie was subdivided into three species in the literature for much of the twentieth century—the black-backed magpie, the white-backed magpie, the western magpie, they were noted to hybridise where their territories crossed, with hybrid grey or striped-backed magpies being quite common. This resulted in them being reclassified as one species by Julian Ford in 1969, with most recent authors following suit. There are thought to be nine subspecies of the Australian magpie, although there are large zones of overlap with intermediate forms between the taxa. There is a tendency for birds to become larger with increasing latitude, the southern subspecies being larger than those further north, except the Tasmanian form, small; the original form, known as the black-backed magpie and classifie
