Beast of Dartmoor

Dartmoor, the ancient upland wilderness of Devon in southwest England, has been the setting for animal mystery stories since at least the 1970s. The Beast of Dartmoor belongs to a broader category of British cryptid known as the Alien Big Cat, a term coined by investigators to describe the large felids, typically panther-like or puma-like in appearance, that have been reported with regularity across the British countryside since the Dangerous Wild Animals Act of 1976 compelled private owners of exotic animals to pay for expensive licensing or surrender their pets. The theory that some owners simply released their animals into the countryside on the eve of the law's implementation is the most widely accepted conventional explanation for British big cat sightings.

On Dartmoor specifically, sightings of a large, black or dark-furred cat have been reported by farmers, hikers, moorland guides, and police officers over several decades. The creature is typically described as similar in size to a leopard, moving with the fluid, low-slung gait of a large felid, with a long tail carried low to the ground. Livestock deaths consistent with big cat predation, including sheep and lambs found with puncture wounds to the neck and kills cached in trees or under ledges in the manner of a leopard, have been documented periodically across the moor.

In 1983, a group of Royal Marines on exercise reported encountering a large black cat on Dartmoor that showed no fear of the soldiers and retreated only slowly when approached. In 1997, a farmer near Yelverton photographed what appeared to be a very large dark cat in a field with sheep for scale comparison. The image was examined by zoologists at Bristol University, some of whom considered it consistent with a large felid, while others remained cautious about drawing firm conclusions from a single photograph.

Britain has no native large wild cat species. The European wildcat exists in Scotland but is a small animal, roughly domestic cat-sized. Melanistic leopards, commonly called black panthers, are the animal most frequently invoked in Beast of Dartmoor reports. Escaped or released pumas and leopards are known to have established at least temporary residence in various parts of the British countryside; in 1980, a puma was captured alive in Inverness-shire, Scotland, in good condition, suggesting it had survived for some years in the wild. Dartmoor's remote terrain, abundant prey, and limited human presence make it one of Britain's most plausible habitats for a self-sustaining cryptid predator.
