Experts believe the snap was taken in Australia, although the photographer behind the candid shot has yet to come forward.The picture, which is believed to be several years old, has resurfaced on a number of occasions, and spawned its own series of memes.
Leather strips glued to ends of bite bars provide a natural surface that encourages high-effort biting and avoids damage to teeth and bones 'And their powerful jaws play a critical role in grabbing and subduing the prey,' The researchers found that small horned frogs, with a head width of about 4.5 centimeters (1.8 inches), can bite with a force of 30 newtons (N) or about 3 kilograms (6.6 pounds).
A scaling experiment, which compared bite force with head and body size, calculated that large horned frogs that are found in the tropical and subtropical moist lowlands of South America, with a head width of up to 10 centimeters (3.9 inches), would have a bite force off almost 500 newtons, which is comparable to reptiles and mammals with a similar head size.
Its average lifespan in captivity is about 16 years, longer than most frogs.
They are often found on window sills or inside houses, drawn by the light.

Leather strips glued to ends of bite bars provide a natural surface that encourages high-effort biting and avoids damage to teeth and bones The researchers measured bite force using a custom-made force transducer, a device which accurately measures the force applied to two places covered with leather when an animal bites them.'The bite of a large Beelzebufo would have been remarkable, definitely not something I would want to experience firsthand.'Sean Wilcox, a Ph D candidate at the University of California – Riverside, and a co-author of the study, says: 'Many people find horned frogs hilarious because of their big heads and fat, round bodies.'Yet, these predators have given us a rare opportunity to learn something more about the biology of a huge extinct frog.' Researchers measured the bite force of South American horned frogs, known as Pacman frogs because of their round shape and large mouth.Been so long since my mother was taken from me I never really thought about when she died.I just happened to do a Google search and found out she was taken October 1st 1982.'Unlike the vast majority of frogs which have weak jaws and typically consume small prey, horned frogs ambush animals as large as themselves – including other frogs, snakes, and rodents,' says Dr Marc Jones, a researcher at the University of Adelaide's School of Biological Sciences and lead author of the research.
