DESCRIPTION:
Baby piglets

The domestic pig typically has a large head, with a long snout which is strengthened by a special prenasal bone and a disk of cartilage at the tip.[2] The snout is used to dig into the soil to find food, and is a very acute sense organ. The dental formula of adult pigs is
3.1.4.3

3.1.4.3
, giving a total of 44 teeth. The rear teeth are adapted for crushing. In the male the canine teeth can form tusks, which grow continuously and are sharpened by constantly being ground against each other.[2]

There are four hoofed toes on each foot, or trotter, with the two larger central toes bearing most of the weight, but the outer two also being used in soft ground.[3]

Most domestic pigs have rather a sparse hair covering on their skin, although woolly-coated breeds, such as the Mangalitsa, are raised.[4]

Pigs possess both apocrine and eccrine sweat glands, although the latter appear limited to the snout and dorsonasal areas.[5] Pigs, however, like other "hairless" mammals (e.g. elephants, rhinos, and mole-rats), do not use thermal sweat glands in cooling.[6] Pigs are also less able than many other mammals to dissipate heat from wet mucous membranes in the mouth through panting. Their thermoneutral zone is 16 to 22 °C.[7] At higher temperatures, pigs lose heat by wallowing in mud or water; although it has been suggested that wallowing may serve other functions, such as protection from sunburn, ecto-parasite control, and scent-marking.[8]

Pigs are one of four known mammalian species which possess mutations in the nicotinic acetylcholine receptor that protect against snake venom. Mongooses, honey badgers, hedgehogs, and pigs all have modifications to the receptor pocket which prevents the snake venom α-neurotoxin from binding. These represent four separate, independent mutations.[9]

Female hogs reach sexual maturity at 3–12 months of age and come into estrus every 18–24 days if they are not successfully bred. The gestation period averages 112–120 days.[10]

Star Wars is an American epic space opera franchise, centered on a film series created by George Lucas. It depicts the adventures of various characters "a long time ago in a galaxy far, far away".

The franchise began in 1977 with the release of the film Star Wars (subtitled Episode IV: A New Hope in 1981[2][3]), which became a worldwide pop culture phenomenon. It was followed by the successful sequels The Empire Strikes Back (1980) and Return of the Jedi (1983); these three films constitute the original Star Wars trilogy. A prequel trilogy was released between 1999 and 2005, which received mixed reactions. A sequel trilogy began in 2015 with the release of Star Wars: The Force Awakens. All seven films were nominated for Academy Awards (with wins going to the first two films) and have been commercial successes, with a combined box office revenue of $7.471 billion,[4] making Star Wars the third highest-grossing film series.[5] Spin-off films include Star Wars: The Clone Wars (2008) and Rogue One (2016), which is the first in an upcoming series of anthology films.

The series has spawned an extensive media franchise—the Star Wars expanded universe—including books, television series, computer and video games, and comic books, resulting in significant development of the series's fictional universe. Star Wars also holds a Guinness World Records title for the "Most successful film merchandising franchise. In 2015, the total value of the Star Wars franchise was estimated at USD $41.9 billion,[6] making Star Wars the second highest-grossing media franchise of all time.

In 2012, The Walt Disney Company acquired Lucasfilm for $4.06 billion and earned the distribution rights to all subsequent Star Wars films, beginning with the release of The Force Awakens in 2015.[7] The former distributor, 20th Century Fox, retains the physical distribution rights to the first two Star Wars trilogies, owning permanent rights for the original 1977 film and holding the rights to Episodes I–III, V, and VI until May 2020.[8][9] Walt Disney Studios owns digital distribution rights to all the Star Wars films, excluding A New Hope.[9][10]
