Rabbit

• 1. Introduction

  ›

  Rabbits have been sentenced to death by a name. On the Isle of Portland in Dorset, older residents still refuse to say the word "rabbit" aloud, substituting "long ears" or "underground mutton" to avoid the bad luck they believe the creature brings. This centuries-old dread traces back to the quarrying trade, where rabbits burrowed beneath the towering stacks of unsellable stone until the walls gave way, burying workers beneath them. That a small, soft-eyed herbivore could carry such a charge of terror points to something peculiar about the rabbit's place in human life. Across every continent where they have arrived, rabbits have inspired fear, reverence, appetite, and affection in equal measure. They are prey animals who became symbols of cunning. They are livestock who became pets. They are ecological nuisances who became cartoon icons. The questions this documentary will explore are deceptively simple: what is a rabbit, really, and how did a creature weighing a few pounds end up woven so deeply into human culture, agriculture, mythology, and even law?

• 2. A Tangled Family Tree

  ›

  Oryctolagus cuniculus, the European rabbit, is the ancestor of every domestic rabbit breed alive today. That single species has been introduced on every continent except Antarctica, making it one of the most widely transplanted mammals on Earth. Yet the family to which it belongs, Leporidae, is far older and stranger than most people realize. The earliest ancestor of rabbits and hares lived 55 million years ago in what is now Mongolia. For most of scientific history, rabbits were classified alongside rodents in the order Rodentia, a grouping that persisted until 1912, when they were moved into their own order, Lagomorpha. The reclassification was driven by anatomy: lagomorphs possess two sets of incisor teeth, one behind the other, while rodents have only one. In rabbits, all teeth continue to grow throughout life; in most rodents, only the incisors share that property. Carl Linnaeus originally grouped rabbits with rodents under the class Glires, and modern molecular biology has partially vindicated him. DNA studies in the 2000s, along with fossil and retrotransposon evidence, confirmed that rodents and lagomorphs share a common ancestor and belong together in the superorder Glires, even if they are not the same order. The shared history explains why the two groups look superficially alike; for a long time, their resemblance was attributed to convergent evolution, but the genetic record argues for genuine common lineage. Today, the family Leporidae contains more than 70 extant species across 11 genera, and the genus Lepus alone accounts for 32 of those species. Among the more obscure members are the pygmy rabbit of North America, the volcano rabbit of Mexico, and the Sumatran striped rabbit, each with a distribution so limited that local habitat loss poses an existential threat.

• 3. Built to Run

  ›

  A rabbit's hind legs are longer than its front legs, and that asymmetry is the key to almost everything about how the animal survives. The hind limbs are built for explosive acceleration: the femur, tibia, and fused fibula work together with four main muscle groups - hamstrings, quadriceps, dorsiflexors, and plantar flexors - to generate rapid, powerful thrusts. The quadriceps handle force production during jumps; the hamstrings contribute short bursts of action. When not moving, rabbits plant their feet flat on the ground in a plantigrade posture. The moment they begin to run, they shift onto their toes in a digitigrade stance, the same mechanical advantage used by cats and dogs. The hind feet have four long, webbed toes; the webbing prevents the foot from spreading under the force of each landing. Unlike most digitigrade animals, rabbits have no paw pads. Instead, dense compressed hair cushions the underfoot. Rabbits that generate less muscular force are more prone to osteoporosis, because bone density in rabbits is directly tied to the mechanical stress placed on the skeleton by muscle action. Their field of vision reinforces the escape strategy. The position of the eyes and the size of the cornea give the rabbit a panoramic view of nearly 360 degrees, with a horizontal retinal region called a visual streak where both rod and cone densities peak, enabling horizon scanning with almost no head movement. The one blind spot sits directly below the nose, which is why rabbits rely on their lips and whiskers to identify what they are eating. Blinking happens only two to four times an hour. The ears serve double duty. According to Allen's rule, which was originally derived from comparing Lepus species across North American climates, endothermic animals in warm environments have larger appendages; rabbit and hare ear surface area follows this pattern. Above 30 degrees Celsius, the ears are theorized to disperse excess body heat, and a rabbit's optimal body temperature sits in the range of 38.5 to 40.0 degrees Celsius. Because rabbits have few to no sweat glands, the vascular network running through the pinnae, along with arteriovenous shunts, regulates blood flow to maintain that narrow thermal window.

• 4. Domestication and Cuniculture

  ›

  Romans were raising European rabbits in enclosed stone-walled enclosures called leporaria from at least the first century BC in Hispania. That practice, known today as cuniculture, eventually spread across Europe and produced hundreds of distinct breeds. Selective breeding began in earnest during the Middle Ages, and since the early 19th century many breeds have been kept as pets rather than as livestock. The earliest domesticated breeds were bred primarily for meat, with an emphasis on faster growth at younger ages; modern domestic rabbits now range in size from dwarf to giant. The Rex rabbit was developed for its distinctive fur, and the various Angora breeds are raised for wool: the fiber is sheared, combed, or plucked from the animal and then spun into yarn. In 1986, France alone produced as many as 70 million rabbit skins in a single year, compared to 25 million mink pelts produced at the same time. The comparison is instructive: rabbit fur is largely a byproduct of meat production, whereas minks are bred primarily for their pelts. Some strains of European rabbit have also been bred as research subjects; the New Zealand white is the most familiar example, developed specifically for laboratory use. The scale of global rabbit meat production is striking. Approximately 1.2 billion rabbits are slaughtered each year for meat worldwide, producing an estimated 2 million tons annually. In 1994, Malta led all nations in per capita consumption at 8.89 kilograms per person, followed by Italy at 5.71 kilograms and Cyprus at 4.37 kilograms. China, Russia, Italy, France, and Spain were the largest producers. In China, rabbit meat is particularly associated with Sichuan cuisine, featuring stewed rabbit, spicy diced rabbit, and spicy rabbit heads, the last of which have been compared to spicy duck neck. Rabbit meat also appears in Moroccan cuisine, cooked in a tajine with raisins and grilled almonds added in the final minutes.

• 5. Reproduction and Survival

  ›

  The female rabbit does not undergo a standard estrus cycle. Ovulation is triggered by mating itself, a mechanism called induced ovulation. The average female rabbit becomes sexually mature between three and eight months of age and can conceive at any point during the year for the remainder of her life, though egg and sperm production begin to decline after three years. In species within the genus Oryctolagus, reproduction stops entirely at six years of age. Gestation lasts 27 to 30 days, and the relationship between litter size and gestation length runs in a counterintuitive direction: a longer pregnancy tends to yield a smaller litter, while a shorter one produces a larger one. A single litter can contain anywhere from one to twelve kits. After birth, the mother nurses her young approximately once every 24 hours, spending most of her time away from the nest; the female can become pregnant again as early as the following day. More than half of all rabbit pregnancies end in abortion, with the embryos resorbed into the mother's body. Vitamin deficiencies are a major cause in domestic animals. Despite this high embryo mortality, the capacity for year-round reproduction makes the overall reproductive rate extraordinary. Newborn kits are altricial: born hairless and blind in burrows or buried nests, they are entirely dependent on the mother. They sleep as many as 22 hours a day before leaving the nest. The diseases that threaten rabbit populations are serious. Rabbit hemorrhagic disease was first described in domestic Angora rabbits imported from Germany to Jiangsu, China in 1984, then spread rapidly to Korea, Italy, and the rest of Europe. From 1988, it appeared in the Americas, first in Mexico, though outbreaks remained infrequent because the original virus only affected European rabbits. A new strain, RHDV2, which can also infect wild lagomorphs including hares, was detected for the first time in France in 2010 and has since reached Canada, Australia, and the United States. Before antibiotics such as doxycycline and gentamicin became available, the death rate from tularemia, a disease associated with handling infected rabbits, stood at 60 percent; it has since fallen to less than 4 percent.

• 6. Ecology and Invasion

  ›

  In Mediterranean Europe, rabbits are the primary prey of red foxes, badgers, and Iberian lynxes, anchoring a food web that depends on their presence in large numbers. The longest-lived rabbit on record, a domesticated European rabbit in Tasmania, died at age 18; wild eastern cottontails, by contrast, typically live one to five years. When the European rabbit is removed from its native ecosystem or introduced into a foreign one, the consequences ripple outward rapidly. In Australia and New Zealand, rabbits are regarded as so destructive to agriculture that landowners are legally obliged to control them. The methods used include gassing of warrens, fencing, shooting, snaring, and ferreting, but the most effective controls have been biological: myxomatosis and calicivirus. Rabbit meat was once widely sold in Sydney, where European rabbits had been introduced deliberately for hunting, before myxomatosis was intentionally deployed to collapse the feral population. A stranger ecological hazard has been documented in Chile, where the European rabbit is an invasive species. Rabbits there have been observed catching fire and spreading wildfires, though forest experts have disputed the relevance of this mechanism, suggesting a burning rabbit could travel only a few meters. No formal scientific investigation into fire-spreading rabbits is known to exist; the evidence remains anecdotal. A 2003 genetic study on domestic rabbits in China found that so-called Chinese rabbits were introduced from Europe and that genetic diversity in Chinese rabbits was very low, reflecting the narrow founding population that accompanied European colonization of trade routes. The South American rabbit fauna followed a similarly recent trajectory: rabbits entered South America as part of the Great American Interchange, and the European rabbit only reached much of the continent's Southern Cone in the late 19th century.

• 7. Mythology and Symbol

  ›

  In Aztec mythology, four hundred rabbit gods known as the Centzon Totochtin, led by Ometochtli or Two Rabbit, represented fertility, parties, and drunkenness. That pantheon captures something enduring about the rabbit's symbolic range: it has rarely stood for just one thing. In Central African tradition, the common hare is called Kalulu and appears as a trickster figure whose cunning defeats stronger adversaries. In Anishinaabe belief, held by the Ojibwe and other Native American peoples, Nanabozho, or Great Rabbit, is an important deity connected to the creation of the world. In Chinese folklore, rabbits accompany Chang'e on the Moon, and the moon rabbit is a central image of the Mid-Autumn Festival. In Japanese tradition, rabbits live on the Moon making mochi, a reading of the pattern of dark patches on the lunar surface as a rabbit pounding at a mortar; in some versions of the story, the substance being produced is a potion of immortality. Korean mythology places rabbits on the Moon as well, where they make rice cakes called tteok. The constellation Lepus, named for the rabbit, was catalogued by Ptolemy around 150 CE. Up until the late 18th century, a widespread belief held that rabbits and hares were hermaphrodites, lending them an association with sexual ambiguity in European culture. The Easter Bunny figure originated in German folklore before spreading to America and beyond. In Jewish folklore, rabbits are associated with cowardice, a usage that persists in contemporary Israeli Hebrew, though the original Hebrew word shfanim actually referred to the hyrax; early translators working outside the hyrax's native range substituted rabbit by mistake. The earliest recorded use of a rabbit's foot as a good-luck amulet dates to around 600 BC in Europe. Buddhism, Christianity, and Judaism all have connections to the three rabbits motif, an ancient circular design whose meaning has been read as everything from "peace and tranquility" to the Holy Trinity. The rabbit's foot amulet is one of the more durable exports of this symbolic tradition, carried in many parts of the world as protection against misfortune.

• 8. Pop Culture and Misconception

  ›

  Bugs Bunny's carrot-eating habit, which helped shape a global association between rabbits and carrots, was modeled on Peter Warne, the character played by Clark Gable in the 1934 romantic comedy It Happened One Night. Wild rabbits do not naturally prefer carrots; the misperception has led some owners of domestic rabbits to feed their animals carrot-heavy diets, despite carrots being high in sugar and potentially harmful in excess. Oswald the Lucky Rabbit was a popular cartoon character in the 1920s, preceding Bugs Bunny by more than a decade. Anthropomorphized rabbits have appeared throughout literature and film: the White Rabbit and the March Hare in Alice's Adventures in Wonderland, the characters of Watership Down, Robert Lawson's Rabbit Hill, and the Peter Rabbit stories by Beatrix Potter. The Playboy Bunny uses the rabbit to juxtapose sexuality and innocence, while the Energizer Bunny and the Duracell Bunny invoke endurance. The Belgian hare, despite its name, is not a hare at all but a domestic rabbit selectively bred to resemble one, most likely from Flemish Giant stock. The "rabbit test" was a term first used in 1949 for the Friedman test, an early pregnancy diagnostic. A widespread misconception held that the rabbit died if the test confirmed pregnancy, giving rise to the phrase "the rabbit died" as a euphemism for a positive result. Rabbits have also been launched into space orbit. In Britain outside of Portland and across much of North America, saying "rabbit rabbit rabbit" on waking on the first day of each month is believed in some traditions to bring good luck for the month ahead, one of many apotropaic superstitions tied to the animal. The word "bunny" itself was attested by the 1680s as a diminutive of "bun", a term used in Scotland to refer to both rabbits and squirrels.
