A water deity is a deity in mythology associated with water or various bodies of water. Water deities are common in mythology and were usually more important among civilizations in which the sea or ocean, or a great river was more important. Another important focus of worship of water deities has been springs or holy wells.

As a form of animal worship, whales and snakes (hence dragons) have been regarded as godly deities throughout the world (as are other animals such as turtles, fish, crabs, and sharks). In Asian lore, whales and dragons sometimes have connections. Serpents are also common as a symbol or as serpentine deities, sharing many similarities with dragons.

A dragon is a magical legendary creature that appears in the folklore of multiple cultures worldwide. Beliefs about dragons vary considerably through regions, but dragons in Western cultures since the High Middle Ages have often been depicted as winged, horned, and capable of breathing fire. Dragons in Eastern cultures are usually depicted as wingless, four-legged, serpentine creatures with above-average intelligence. Commonalities between dragons' traits are often a hybridization of reptilian, mammalian, and avian features.

A hide or skin is an animal skin treated for human use. The word "hide" is related to the Dutch word huid and the German word Haut, which mean skin. The industry defines hides as "skins" of large animals e.g. cow, buffalo; while skins refer to "skins" of smaller animals: goat, sheep, deer, pig, fish, alligator, snake, etc.Common commercial hides include leather from cattle and other livestock animals, buckskin, alligator skin and snake skin. All are used for shoes, clothes, leather bags, belts, or other fashion accessories. Leather is also used in cars, upholstery, interior decorating, horse tack and harnesses. Skins are sometimes still gathered from hunting and processed at a domestic or artisanal level but most leather making is now industrialized and large-scale. Various tannins are used for this purpose. Hides are also used as processed chews for dogs or other pets.

The term "skin" is sometimes expanded to include furs, which are harvested from various species, including cats, mustelids, and bears.

The boa constrictor (scientific name also Boa constrictor), also known as the common boa, is a species of large, non-venomous, heavy-bodied snake that is frequently kept and bred in captivity. The boa constrictor is a member of the family Boidae. The species is native to tropical South America. A staple of private collections and public displays, its color pattern is highly variable yet distinctive. Four subspecies are recognized.

The wildlife of Brazil comprises all naturally occurring animals, plants, and fungi in Brazil, which is the most biodiverse country in the world. Home to 60% of the Amazon rainforest, which accounts for approximately one-tenth of all species in the world, Brazil has the greatest biodiversity of any country on the planet. It has the most known species of plants (60,000), freshwater fish (3,000), amphibians (1,188), snakes (430), insects (90,000) and mammals (775). Brazil is also the country with the most native species of eatable fruits (over 300).It also ranks third on the list of countries with the most bird species (1,971) and the third with the most reptile species (848). The number of fungal species is unknown (+3,300 species). Approximately two-thirds of all species worldwide are found in tropical areas, often coinciding with developing countries such as Brazil. Brazil is second only to Indonesia as the country with the most endemic species.

Serpents (Hebrew: נָחָשׁ, romanized: nāḥāš) are referred to in both the Hebrew Bible and the New Testament. The symbol of a serpent or snake played important roles in the religious traditions and cultural life of ancient Greece, Egypt, Mesopotamia, and Canaan. The serpent was a symbol of evil power and chaos from the underworld as well as a symbol of fertility, life, healing, and rebirth.

Nāḥāš (נחש‎), Hebrew for "snake", is also associated with divination, including the verb form meaning "to practice divination or fortune-telling". Nāḥāš occurs in the Torah to identify the serpent in the Garden of Eden. Throughout the Hebrew Bible, it is also used in conjunction with seraph to describe vicious serpents in the wilderness]. The tannin, a dragon monster, also occurs throughout the Hebrew Bible. In the Book of Exodus, the staves of Moses and Aaron are turned into serpents, a nāḥāš for Moses, a tannin for Aaron. In the New Testament, the Book of Revelation makes use of ancient serpent and the Dragon several times to identify Satan or the Devil (Revelation 12:9; 20:2). The serpent is most often identified with the hubristic Satan, and sometimes with Lilith.

A tetrapod (/ˈtɛtrəˌpɒd/; from Ancient Greek τετρα- (tetra-) 'four' and πούς (poús) 'foot') is any vertebrate animal of the clade Tetrapoda (/tɛˈtræpədə/). Tetrapods include all extant and extinct amphibians and amniotes, with the latter in turn evolving into two major clades, the sauropsids (reptiles, including dinosaurs and therefore birds) and synapsids (extinct "pelycosaurs", therapsids and all extant mammals, including humans). Hox gene mutations have resulted in some tetrapods becoming limbless (snakes, legless lizards, and caecilians) or two-limbed (cetaceans, sirenians, some lizards, kiwis, and the extinct moa and elephant birds). Nevertheless, they still qualify as tetrapods through their ancestry, and some retain a pair of vestigial spurs that are remnants of the hindlimbs.

Tetrapods evolved from a group of semiaquatic animals within the tetrapodomorphs which, in turn, evolved from ancient lobe-finned fish (sarcopterygians) around 390 million years ago in the Middle Devonian period. Early tetrapodomorphs were transitional between lobe-finned fishes and true four-limbed tetrapods, though most still fit the body plan expected of other lobe-finned fishes. The oldest fossils of four-limbed vertebrates (tetrapods in the broad sense of the word) are trackways from the Middle Devonian, and body fossils became common near the end of the Late Devonian, around 370–360 million years ago. These Devonian species all belonged to the tetrapod stem group, meaning that they did not belong to any modern tetrapod group.

The serpent, or snake, is one of the oldest and most widespread mythological symbols. The word is derived from Latin serpens, a crawling animal or snake. Snakes have been associated with some of the oldest rituals known to humankind.

They represent dual expression of good and evil.

A pet, or companion animal, is an animal kept primarily for a person's company or entertainment rather than as a working animal, livestock, or a laboratory animal. Popular pets are often considered to have attractive/cute appearances, intelligence, and relatable personalities, but some pets may be taken in on an altruistic basis (such as a stray animal) and accepted by the owner regardless of these characteristics.

Two of the most popular pets are dogs and cats. Other animals commonly kept include rabbits; ferrets; pigs; rodents such as gerbils, hamsters, chinchillas, rats, mice, and guinea pigs; birds such as parrots, passerines, and fowls; reptiles such as turtles, lizards, snakes, and iguanas; aquatic pets such as fish, freshwater snails, and saltwater snails; amphibians such as frogs and salamanders; and arthropod pets such as tarantulas and hermit crabs. Smaller pets include rodents, while the equine and bovine group include the largest companion animals.

A pest is any organism harmful to humans or human concerns. The term is particularly used for creatures that damage crops, livestock, and forestry or cause a nuisance to people, especially in their homes. Humans have modified the environment for their own purposes and are intolerant of other creatures occupying the same space when their activities impact adversely on human objectives. Thus, an elephant is unobjectionable in its natural habitat but a pest when it tramples crops.

Some animals are disliked because they bite or sting; wolves, snakes, wasps, ants, bees, bed bugs, mosquitos, fleas and ticks belong in this category. Others enter the home; these include houseflies, which land on and contaminate food; beetles, which tunnel into the woodwork; and other animals that scuttle about on the floor at night, like rats, mice, and cockroaches, which are often associated with unsanitary conditions.

Eve is a figure from the Book of Genesis (ספר בראשית) in the Hebrew Bible. According to the origin story of the Abrahamic religions, she was the first woman to be created by God. Eve is known also as Adam's wife.

Her name means "living one" or "source of life". The name has been compared to that of the Hurrian goddess Ḫepat, who was worshipped in Jerusalem during the Late Bronze Age. It has been suggested that the Hebrew name Eve (חַוָּה) bears resemblance to an Aramaic word for "snake" (Old Aramaic language חוה; Aramaic חִוְיָא). The origin for this etymological hypothesis is the rabbinic pun present in Genesis Rabbah 20:11 ( c. 300-500 CE), utilizing the similarity between Heb. Ḥawwāh and Aram. ḥiwyāʾ. Notwithstanding its rabbinic ideological usage, scholars like Julius Wellhausen and Theodor Nöldeke argued for its etymological relevance.

The Lernaean Hydra or Hydra of Lerna (Ancient Greek: Λερναῖα ὕδρα, romanized: Lernaîa Húdrā), more often known simply as the Hydra, is a serpentine lake monster in Greek mythology and Roman mythology. Its lair was the lake of Lerna in the Argolid, which was also the site of the myth of the Danaïdes. Lerna was reputed to be an entrance to the Underworld, and archaeology has established it as a sacred site older than Mycenaean Argos. In the canonical Hydra myth, the monster is killed by Heracles (Hercules) as the second of his Twelve Labors.

According to Hesiod, the Hydra was the offspring of Typhon and Echidna. It had poisonous breath and blood so virulent that even its scent was deadly. The Hydra possessed many heads, the exact number of which varies according to the source. Later versions of the Hydra story add a regeneration feature to the monster: for every head chopped off, the Hydra would regrow two heads. Heracles required the assistance of his nephew Iolaus to cut off all of the monster's heads and burn the neck using a sword and fire.

Albanian paganism comprises the pagan customs, beliefs, rituals, myths and legends of the Albanian people. The elements of Albanian mythology are of ancient Paleo-Balkanic origin and almost all of them are pagan. Ancient paganism persisted among Albanians, and especially within the inaccessible and deep interior – where Albanian folklore evolved over the centuries in a relatively isolated tribal culture and society – it has continued to persist, or at most it was partially transformed by the Christian, Muslim and Marxist beliefs that were either to be introduced by choice or imposed by force. The Albanian traditional customary law (Kanun) has held a sacred – although secular – longstanding, unwavering and unchallenged authority with a cross-religious effectiveness over the Albanians, which is attributed to an earlier pagan code common to all the Albanian tribes. Indeed, the Kanun contains several customary concepts that clearly have their origins in pagan beliefs, including in particular the ancestor worship, animism and totemism, which have been preserved since pre-Christian times. Albanian traditions have been orally transmitted – through memory systems that have survived intact into modern times – down the generations and are still very much alive in the mountainous regions of Albania, Kosovo, Montenegro and western North Macedonia, as well as among the Arbëreshë in Italy, the Arvanites in Greece and the Arbanasi in Croatia.

The old beliefs in sun and moon, light and darkness, sky and earth, fire and hearth, water and springs, death and rebirth, birds and serpents, mountains, stones and caves, sacrifice, and fate are some of the pagan beliefs among Albanians. The Fire (Zjarri) rituals and the Sun (Dielli) and Moon (Hëna) worship are the earliest attested cults of the Albanians. The Sun holds the primary role in Albanian pagan customs, beliefs, rituals, myths, and legends; Albanian major traditional festivities and calendar rites are based on the Sun, worshiped as the god of light, sky and weather, giver of life, health and energy, and all-seeing eye; the sunrise is honored as it is believed to give energy and health to the body. The Moon is worshiped as a goddess, with her cyclical phases regulating many aspects of Albanian life, defining agricultural and livestock activities, various crafts, and human body. The morning and evening star Venus is personified with Prende, associated with dawn, beauty, love, fertility, health, and the protection of women. The cult of the Earth (Dheu) and that of the Sky (Qielli) have a special place. The Fire – Zjarri, evidently also called with the theonym Enji – is deified in Albanian tradition as releaser of light and heat with the power to ward off darkness and evil, affect cosmic phenomena and give strength to the Sun, and as sustainer of the continuity between life and afterlife and between the generations, ensuring the survival of the lineage (fis or farë). To spit into Fire is taboo. The divine power of Fire is used for the hearth and the rituals, including calendar fires, sacrificial offerings, divination, purification, and protection from big storms and other potentially harmful events. Fire worship and rituals are associated with the cult of the Sun, the cult of the hearth (vatër) and the ancestor, and the cult of fertility in agriculture and animal husbandry. Ritual calendar fires are associated with the cosmic cycle and the rhythms of agricultural and pastoral life. Besa is a common practice in Albanian culture, consisting of an oath (be) solemnly taken by sun, by moon, by sky, by earth, by fire, by stone and thunderstone, by mountain, by water, and by snake, which are all considered sacred objects. Associated with human life, bees are highly revered by Albanians. The eagle is the animal totem of all Albanians, associated with the Sky, freedom and heroism. A widespread folk symbol is the serpent (Gjarpër, Vitore, etc.), a totem of the Albanians associated with earth, water, sun, hearth and ancestor cults, as well as destiny, good fortune and fertility. The sun, the moon, the star, the eagle (bird), the serpent, and the bee, often appear in Albanian legends and folk art.

Worm, wurm or wyrm (Old English: wyrm; Old Norse: ormr; Old High German: wurm), meaning serpent, are archaic terms for dragons (Old English: draca; Old Norse: dreki/*draki; Old High German: trahho) in the wider Germanic mythology and folklore, in which they are often portrayed as large venomous snakes and hoarders of gold. Especially in later tales, however, they share many common features with other dragons in European mythology, such as having wings.

Prominent worms attested in medieval Germanic works include the dragon that killed Beowulf, the central dragon in the Völsung Cycle – Fáfnir, Nidhogg (Old Norse: Níðhǫggr), and the great world serpent, Jǫrmungandr, including subcategories such as lindworms and sea serpents.
