This article: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago.  Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales). Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing − their hearing, that is adapted for both air and water, is so well developed that... contains an answer for the question: What is the type of whale that can weigh up to 190 metric tons?, what is it ?

This article: Head VI is an oil-on-canvas painting by the Irish-born figurative artist Francis Bacon, the last of six panels making up his "1949 Head" series. It shows a bust view of a single figure, modeled on Diego Velázquez's Portrait of Innocent X. Bacon applies forceful, expressive brush strokes, and places the figure within a glass cage structure, behind curtain-like drapery. This gives the effect of a man trapped and suffocated by his surroundings, screaming into an airless void. Head VI was the first of Bacon's paintings to reference Velázquez, whose portrait of Pope Innocent X haunted him throughout his career and inspired his series of "screaming popes", a loose series of which there are around 45 surviving individual works. Head VI contains many motifs that were to reappear in Bacon's work. The hanging object, which may be a light switch or curtain tassel, can be found even in his late paintings. The geometric cage is a motif that appears as late as his 1985–86 masterpiece Study for a Self-Portrait—Triptych. Head VI was first exhibited in November 1949 at the Hanover Gallery in London, in a showing organised by one of the artist's early champions, Erica Brausen. At the time, Bacon was a highly controversial but respected artist, best known for his 1944 Three Studies for Figures at the Base of a Crucifixion, which made him the enfant terrible of British art. Head VI drew a mixed reaction from art critics; John Russell, later Bacon's biographer, at the time dismissed it as a cross between "an alligator shorn of its jaws and an accountant in pince-nez who has come to a bad end". In 1989 Lawrence Gowing wrote that the "shock of the picture, when it was seen with a whole series of heads ... was indescribable. It was everything unpardonable. The paradoxical appearance at once of pastiche and iconoclasm was indeed one of Bacon's most original strokes." Art critic and curator David Sylvester described it as a seminal piece from Bacon's unusually productive 1949–50 period, and one of Bacon's finest popes. contains an answer for the question: What is the first name of the person Russell was the biographer for?, what is it ?

This article: After John Dortmunder is released from his latest stint in prison, he is approached by his brother-in-law, Andy Kelp, about another job. Dr. Amusa seeks a valuable gem in the Brooklyn Museum that is of great significance to his people in his country in Africa, stolen during colonial times and then re-stolen by various African nations. Dortmunder and Kelp are joined by driver Stan Murch and explosives expert Allan Greenberg, concocting an elaborate plan to steal the gem. Although the scheme (and each subsequent one) is carefully planned—and keeps increasing in cost—something always goes awry, and the quartet has to steal the diamond again and again. First off, the diamond is swallowed by Greenberg when he alone gets caught by the museum guards during the initial heist. Dortmunder, Kelp, and Murch, at the urging of Greenberg's rotund father Abe, a lawyer, help Greenberg escape from state prison, but they then find he does not have the diamond. After Greenberg tells his partners he hid the rock in the police station (after bodily evacuating it), the quartet break into the precinct jail by helicopter, but the rock is not where Greenberg hid it. Greenberg discloses that his father Abe was the only other person who knew where it was. It isn't until Murch, disguised as the grunting muscle man "Chicken," threatens Abe with being thrown down an elevator shaft, that Abe gives up the location of the diamond—his safe deposit box, and he also gives up the key to it.  However, Dortmunder cannot access the box because of bank vault security, and the gang leaves Abe in Dr. Amusa's office while they come up with a plan. contains an answer for the question: After accepting the job, what are the full names of the two experts who join the former prisoner?, what is it ?
