The hispid hare (Caprolagus hispidus), also known as the Assam rabbit or bristly rabbit, is a critically endangered species of rabbit native to South Asia. It is distinguished by its coarse, bristly fur and is the sole member of the genus Caprolagus. Once believed extinct, it was rediscovered in 1971 and now survives in fragmented populations across India, Nepal, and Bangladesh, facing severe threats from habitat loss.

About Caprolagus
The Hispid Hare (Caprolagus hispidus)
The hispid hare, scientifically known as Caprolagus hispidus and also referred to as the Assam rabbit or bristly rabbit, is a critically endangered species native to South Asia. It is the sole representative of the genus Caprolagus and is notable for its coarse, bristly fur, a distinctive trait among lagomorphs. Its appearance is characterized by dark-brown fur, a large nose, and relatively short ears compared to other hares found in the same regions.
Rediscovery and Distribution
Once thought to be extinct, the hispid hare was rediscovered in Assam, India, in 1971. Since then, it has been found in scattered, isolated populations across India, Nepal, and Bangladesh. Historically, its range extended along the southern foothills of the Himalayas. Today, the species' habitat is severely fragmented and covers an estimated area of less than 500 square kilometers, spread over a broader region of 5,000 to 20,000 square kilometers.
Habitat and Threats
The hispid hare inhabits successional tall grasslands, particularly areas dominated by elephant grass, which provide both food and cover. These crucial grassland habitats are highly fragmented. The species seeks refuge in marshy areas or grasses near riverbanks during the dry season, but populations near rivers are vulnerable to flooding. The primary threats to the hispid hare are habitat loss and degradation due to increasing agriculture, flood control measures, human development, and the burning and collection of thatch grasses. Overgrazing by cattle also contributes to habitat degradation.
Physical Characteristics and Behavior
The hispid hare's fur is harsh and bristly, dark brown on the back due to a mix of black and brown hairs, with brown on the chest and whitish on the abdomen. Its tail is brown and measures between 25 to 38 millimeters in length, and its ears are short, between 54 to 61 millimeters. Adult males typically weigh between 1,810 to 2,610 grams, with a mean of 2,248 grams, while females average around 2,518 grams. It is a crepuscular animal, most active at dawn and dusk. Its diet consists of grasses and leaves. Predators include birds of prey, cats, civets, jackals, weasels, and foxes.
Conservation Efforts
Due to its precarious status, the hispid hare has been listed as Endangered on the IUCN Red List since 1986. Conservation efforts are ongoing and focus on community education and further research into the species' distribution and ecological needs. Recommendations include developing controlled burning systems that do not interfere with the breeding season. Breeding the hispid hare in captivity has been described as "very difficult," highlighting the challenges in ensuring its long-term survival.

Frequently Asked Questions
What makes the hispid hare's fur distinctive?
The hispid hare is named for its coarse and bristly fur, which is unusual for a rabbit or hare. The fur is dark brown on its back, mixed with black and brown hairs, and lighter on its chest and abdomen.
Where can the hispid hare be found today?
Today, the hispid hare's distribution is limited and fragmented, primarily found in isolated populations across northern India, southern Nepal, and eastern Bhutan. Its historic range was much larger, extending along the southern foothills of the Himalayas.
What are the main threats to the hispid hare's survival?
The primary threat to the hispid hare is the loss and fragmentation of its grassland habitat. This is driven by increasing agriculture, flood control measures, human development, and the burning and collection of thatch grasses.
How does the hispid hare differ from the Indian hare?
The hispid hare can be distinguished from the Indian hare by its shorter ears, which do not extend past its fur, and its completely brown tail. The Indian hare, in contrast, has longer ears and a tail with a white underside.
What is the conservation status of the hispid hare?
The hispid hare has been listed as Endangered on the IUCN Red List since 1986. This status reflects the severe decline in its population and the ongoing threats to its habitat.
What is the diet of the hispid hare?
The hispid hare is herbivorous and feeds on grasses and leaves. It shows a preference for specific grasses such as kans grass, cogongrass, and various species within the Narenga genus, depending on availability.

Pentalagus
The Amami rabbit (Pentalagus furnessi), also known as the Ryukyu rabbit, is a unique, dark-furred species endemic to the Japanese islands of Amami Ōshima and Tokunoshima. Considered a "living fossil," it represents an ancient lineage of rabbits that once inhabited the Asian mainland. Its distinctiveness lies in its smaller ears, unique molar count, and specialized habitat requirements.
Romerolagus
The volcano rabbit, Romerolagus diazi, is a small, primitive rabbit species endemic to the volcanic slopes of central Mexico. It is distinguished by its short, rounded ears, short legs, and thick fur, and is known for its unique high-pitched alarm calls, a behavior more typical of pikas. Facing significant population declines due to habitat loss and human activities, it is classified as an endangered species.
Poelagus
The Bunyoro rabbit (Poelagus marjorita), also known as the Uganda grass hare, is a medium-sized, greyish-brown, nocturnal, plant-eating mammal found in central Africa. It is the sole member of the genus Poelagus and is distinctive for its shorter ears and hind legs compared to other African leporids, as well as its coarser fur. While historically considered abundant, recent sightings have been infrequent, leading to concerns about its distribution.
