Tasmanian devil, extremely voracious marsupial, or pouched mammal, of the dasyure family, now found only on the island of Tasmania. The Tasmanian devil, Sarcophilus harrisi, formerly found also in Australia, is about 2 ft (60 cm) long, excluding the 12-in. (30-cm) tail. It has a large head, with powerful jaws, and weak hindquarters. Its blackish fur is marked with white patches on the throat, on each side, and on the rump. The animal has a fierce appearance. It is very strong for its size and preys on animals larger than itself, such as small kangaroos, as well as on rodents, lizards, and other small animals. It lives in burrows in rocky areas. Like the related thylacine, or Tasmanian wolf, the Tasmanian devil has been relentlessly hunted because of its inroads on domestic livestock and poultry. Although it has survived in sizable numbers in remote areas of the island, it is now threatened by a fatal facial cancer that has spread steadily and decimated infected populations since the late 1990s. The lack of genetic diversity in the marsupial has facilitated the cancer's spread. It is classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Marsupialia, family Dasyuridae.

Robert the Devil, hero of a medieval legend. He was sold to the devil by his mother before his birth but upon discovering the fact did penance and was able to purify himself of his many sins. The tale may have been derived from the life of Robert I, duke of Normandy. The story exists in several French and English versions and is the basis of Meyerbeer's opera Robert le Diable.

Distilled liquor made from sugarcane products, primarily molasses. It is first mentioned in records from Barbados circa 1650. Rum figured in the slave trade: slaves from Africa were traded in the West Indies for molasses, the molasses was made into rum in New England, and the rum was then traded to Africa for more slaves. British sailors received regular rum rations from the 18th century until the 1970s. Two major types are marketed. The light-bodied rums, traditionally of Puerto Rico and Cuba, employ cultivated yeast and are distilled in continuous-operation stills before being blended and aged one to four years. The heavier dark rums, traditionally of Jamaica, employ yeast spores from the air and are distilled in simple pot stills before being blended and aged five to seven years. Rum is drunk straight or mixed and is used in dessert sauces and other dishes.

Worship of Satan, or the devil, the personality or principle regarded in the Judeo-Christian tradition as embodying absolute evil, in complete antithesis to God. Cults associated with satanism have been documented, however sketchily, back to the 17th century. Their central feature is the black mass, a corrupted and inverted rendition of the Christian Eucharist. Practices are said to include animal sacrifice and deviant sexual activity. Worship is motivated by the belief that Satan is more powerful than the forces of good, and so is more capable of bringing about the results sought by his adherents.

or devil ray or devilfish

Any of several genera of warm-water marine rays, constituting the family Mobulidae, that are wider than they are long. Extensions of the pectoral fins project from the front of the head, looking like devils' horns; these sweep plankton and small fishes into their mouths. The long, whiplike tail may have one or more stinging spines. Mantas swim near the surface by flapping their pectoral fins. The largest species, the powerful but inoffensive Atlantic manta, or giant devil, ray (Manta birostris), may grow to over 23 ft (7 m) wide; contrary to old tales, it does not envelop and eat divers.

Spirit or power of evil. Though sometimes used to refer to demons, the term more often designates the prince of evil spirits. In the Bible the Devil is known as Satan, Beelzebub, and Lucifer. In Judaism, Satan emerges as subservient to God and as an adversary and accuser of Job and other humans. In postbiblical traditions he emerges as the tempter of humankind and is responsible for all the sins in the Bible. Christian theology holds that his main task is to tempt humans to reject the way of life and redemption in favour of sin and death. In the Qurhamzahān the Devil is frequently associated with Iblīs; he tempts the unfaithful but not the true believer. In Hinduism there is no principal devil, although there are a variety of demons or devilish beings. Buddhists also recognize the existence of many demons, and Mara, the Buddha's opponent and tempter, is sometimes identified as a specific devil.
