- Bite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal adjusted for its body mass, while also taking factors like the allometry effects. The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms.

BFQ [Bite force quotient, see notes 1]: 72.77 The cheetah (Acinonyx jubatus), known for its incredible speed and agility, is a big cat in the subfamily Felinae that inhabits most of Africa and parts of Iran. The cheetah can run as fast as 109.4 to 120.7 km/h or 68.0 to 75.0 mph (the fastest properly authenticated cheetahhit 61 mph or 98.1 km/h, tho...
BFQ: 114.3 The domestic dog (Canis lupus familiaris or Canis familiaris) is a domesticated canid that has been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Extensive genetic studies undertaken during the 2010s indicate that dogs diverged from an extinct wolf-like canid in Eurasia 40,000 years ...
BFQ: 131.1 The African wild dog, African hunting dog, or African painted dog (Lycaon pictus) is a canid native to Sub-Saharan Africa. It is the largest of its family in Africa, and the only member of the genus Lycaon, which is distinguished from Canis by its fewer toes and dentition, which is highly specializedfor a hypercarnivorous diet (see notes...
BFQ: 99.9 The snow leopard (Panthera uncia) is a large cat native to the mountain ranges of Central and South Asia. Snow leopards inhabit alpine and subalpine zones at elevations from 3,000 to 4,500 meters (9,800 to 14,800 feet). In the northern range countries, they also occur at lower elevations. It is the smallest member of the Panthera genus. A...
BFQ: 115.4 The giant otter (Pteronura brasiliensis) is a semi-aquatic mammal found in South America, known for its impressive size and social behavior. They can reach up to 1.7 meters (5.6 feet). Giant otters have a relatively powerful bite compared to other otter species. The specific bite force of an animal is influenced by various factors, inclu...
BFQ: 127.3 The gray wolf or grey wolf (Canis lupus), also known as the timber wolf or western wolf is the largest extant member of its family, with males averaging 43-45 kg (95-99 lb), and females 36-38.5 kg (79-85 lb). It is a canid native to the wilderness and remote areas of North America and Eurasia. It is a highly adaptable and social carnivor...
BFQ: 118.8 The cougar (Puma concolor), also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas. They have a sleek and muscular body with a small, broad head and a long, thick tail. Their bodies are built for agility and stealth. Adult cougars typically measure between 6...
BFQ: 128.9 The striped hyena (Hyaena hyaena) is the smallest of the true hyenas. It is native to North and East Africa, the Middle East, the Caucasus, Central Asia, and the Indian subcontinent. Though it has a habit of feigning death when attacked, it has also been known to stand its ground against larger predators such as leopards in disputes over...
BFQ: 59.9 The sloth bear (Melursus ursinus), also known as the Stickney bear or labiated bear, is a nocturnal insectivorous (eats insects) bear species found wild within the Indian Subcontinent. It evolved from ancestral brown bears during the Pleistoceneand shares features found in insect-eating mammals through convergent evolution. Sloth bears ha...
BFQ: 135.9 The brown hyena (Hyaena brunnea, formerly Parahyaena brunnea) is currently the rarest species of hyena. It is found in Namibia, Botswana, western and southern Zimbabwe, southern Mozambique, and South Africa. The brown hyena is a medium-sized hyena with a distinct appearance. It has a shaggy brown coat that is coarse and long, which gives...
