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. [1] The BFQ was first applied by Wroe et al. (2005) in a paper comparing bite forces, body masses and prey size in a range of living and extinct mammalian carnivores, later expanded on by Christiansen & Wroe (2007 ...
Some other species that may bite humans include urban animals such as feral cats, spiders, and snakes. Other common bites to humans are inflicted by hematophagous insects and arthropods, such as mosquitoes , fleas , lice , bedbugs , and ticks (whose "bites" are actually a form of stinging rather than true biting).
Those with greater bite forces require less time to consume certain prey items as a greater bite force can increase the net rate of energy intake when foraging and enhance fitness in durophagous species. In the order Carnivora there are two dietary categories of durophagy; bonecrackers and bamboo eaters.
A study in 2012 by Karl Bates and Peter Falkingham found that Tyrannosaurus had the most powerful bite of any terrestrial animal that has ever lived, finding an adult Tyrannosaurus could have exerted 35,000 to 57,000 N (7,868 to 12,814 lbf) of force in the back teeth. [209] [210] [211] Even higher estimates were made by Mason B. Meers in 2003. [48]
[9] [10] Bite force measurements from a growth series of Cranwell's horned frog (Ceratophrys cranwelli), suggest that the bite force of a large Beelzebufo—skull width 15.4 cm (6.1 in)—may have been between 500 and 2,200 newtons (110 and 490 lb f). [10]
Larger animals that were likely prey include Diprotodon spp. and giant kangaroos. It seems improbable that Thylacoleo could achieve as high a bite force as a modern-day lion; however, this might have been possible when taking into consideration the size of its brain and skull.
They reported 799–1,199 N (180–270 lb f) with a mean of 959 N (216 lb f), which is not entirely unrealistic given the animal's mass. The bite force is comparable to that of many large carnivores (which have a much smaller mass-to-bite-force ratio); for example, the polar bear has a bite force of roughly 751 N (169 lb f) and the jaguar 1,014 ...
It has been listed as one of the top-10 "focal species" in 2008 by the Evolutionarily Distinct and Globally Endangered project. The Chinese giant salamander is considered to be a "living fossil". [8] Although protected under Chinese law and CITES Appendix I, [1] the wild population has declined by more than an estimated 80% since the 1950s. [9]
