Important information and facts about rabbits
General Introduction
The rabbit is a small to medium-sized mammal belonging to the order Lagomorpha and the family Leporidae. Known for their long ears and short, bushy tail, rabbits are distributed in more than thirty species worldwide, including wild (hares) and domesticated species.
Scientific Classification

Dimensions and Size
Rabbits range in length from 20 cm in the smallest (such as the Pygmy rabbit) to about 50 cm in the larger species.
Weight varies from less than 400 grams in dwarf rabbits to over 7 kg in giant species.
The average lifespan of rabbits in the wild is about two to three years, while domesticated rabbits can live to over ten years in captivity.

Environment, Distribution, and Habitat
Rabbits inhabit a wide range of regions, from dry deserts and tropical forests to wetlands and temperate grasslands. They are found throughout the Northern Hemisphere, from the mid-latitudes of North and South America to Europe, through northern and central Africa, the Indian subcontinent, and as far as the islands of Japan and Sumatra. Some species live in burrows called "morches," which they dig to protect their members from danger and provide a haven for socialization.
Rabbits live in a variety of habitats: from meadows and steppes to forests and mountain plateaus.
Rabbits dig interconnected burrows called "morches" to provide safe shelter from predators and divide their families into smaller families.
Some species (such as the European rabbit) have become invasive in new areas such as Australia and New Zealand, causing environmental disruption.
Appearance
Rabbits are characterized by a plump, oval body covered in soft, dense fur, ranging in color from brown to gray to orange-yellow. They have long ears—each reaching up to 6 centimeters—that act as a fine sensory organ for detecting the smallest sounds emitted by predators. They also help regulate their temperature through blood flow in their microvessels. Their powerful and long hind legs are approximately half their body length, giving them the dual ability to leap long distances and run at high speeds. Each foot has five toes, one of which is smaller and helps the rabbit balance while moving on tiptoes.
Behavior, Reproduction, and Reproductive Cycle
Diet: Grasses, leaves, shoots, and vegetables. Some are nocturnal or crepuscular (active at dawn and dusk).
Defenses: High speed (can exceed 45 km/h), sharp turns, and camouflage.
Reproduction
A rapid birth cycle, occurring approximately every 30 days.
A female (doe) gives birth to between 3 and 12 kits at a time. Kits are born with their eyes closed and depend on their mother for milk until they are 3–4 weeks old.
Rabbits reach sexual maturity at 3–6 months of age, making them one of the fastest-breeding mammals.
Reproductive Cycle
Induced ovulation: Does do not have a regular heat cycle, but instead release eggs in response to copulation.
Early maturation: Does become fertile at 5–6 months of age and remain fertile for approximately four years.
Short gestation: The gestation period lasts approximately 31 days, after which they give birth to between 1 and 12 kits.
Repeated pregnancies: Does can be inseminated again a few days after giving birth, but a gap of at least four weeks between births is recommended to maintain their health.
Importance and Relationship to Humans
Food Source: Rabbit meat is low in fat and rich in protein.
As a pet: They are raised in homes and gardens, and their care requirements include space and a balanced diet.
Industry: Rabbit fur, such as that of the chinchilla, is used in clothing, and the Angora rabbit produces soft wool.
Diet
Rabbits are herbivores, never consuming meat. Their diet consists of soft grasses, clover, and cruciferous plants such as broccoli and Brussels sprouts, in addition to fruits, tender grasses, and sometimes bark. Rabbits have a two-stage digestion: they partially swallow their food, then re-chew the cud to fully break it down, and then ingest small black capsules—the “night suits”—that are extremely rich in vitamins and minerals.
Health and Diseases
The most common diseases are toxoplasmosis, myxomatosis, and rabbit Dutch virus (RHDV).
Domesticated rabbits require annual checkups, regular vaccinations, and special veterinary care for their teeth and ear skin.
Conservation and Challenges
Some species are threatened with extinction due to habitat loss and poaching, such as the Andalusian hare (Bunolagus monticularis) in Spain.
International efforts target habitat restoration and implement breeding and rehabilitation programs for their release into the wild.
Kitts
Newborn kitts are born naked and helpless, with their eyes closed. Their mothers do not receive much daily attention, only nursing them once a day for a few minutes. Their milk is high in protein and fat to compensate for this lack of feeding. The kits are typically weaned around the age of one month, then leave the nest and begin exploring the surrounding area.
Adaptations and Defenses
Hiding: Active at dusk and dawn, when the dim light provides cover from predators.
Panoramic Vision: Their eyes are positioned on both sides of their heads, covering a nearly 360-degree field of vision horizontally, and detecting even dim light in pitch darkness.
Zigzag Running: Thanks to their powerful hind legs, some species (such as the cottontail) can reach speeds of up to 29 km/h (18 mph), with the ability to change direction suddenly to camouflage their pursuers.
Thermoregulation: Excess heat is released through the ears due to their rich blood vessels.
Additional Facts
The Guinness World Record for the tallest rabbit in the world, measuring 129 cm (4.5 in) and weighing 22 kg (54 lb), is a Flemish Giant.
Rabbits are a key component of food chains; they are prey for wolves, foxes, weasels, hawks, eagles, and owls.
They can become a pest in some areas when their populations exceed the environment's ability to replace local plant crops.
Diseases that may be transmitted to humans include: tularemia and rabbit fever.
Conclusion
Rabbits represent a living example of the amazing biodiversity and adaptations within the mammalian kingdom. Thanks to their long ears, ability to regulate their temperature, strong hind legs, and excellent vision, they have been able to inhabit diverse environments, from arid deserts to rainforests. Their unique life cycle—induced ovulation, short gestation, and rapid reproduction—demonstrates their remarkable resilience in the face of environmental pressures.
While rabbits provide vital ecological services through their role in the food chain, soil aeration, and seed dispersal, their overpopulation in some areas can lead to agricultural problems. Humans also share a multifaceted relationship with rabbits, from companion animals to food and industrial resources, to raising awareness about the need for ecological balance and the protection of natural habitats. Recognizing their importance, conserving and protecting their species from extinction, and managing them sustainably in the wild and in captivity will contribute to the continuation of this magnificent species as an integral part of our natural and cultural heritage.
