The bite force is considered the highest of any living or fossil fish, and among the highest of any animal. [33] The pressures generated in those regions were high enough to puncture or cut through cuticle or dermal armor, [33] suggesting that D. terrelli was adapted to prey on free-swimming, armored prey such as ammonites and other placoderms ...
They placed the bite force of the latter between 108,514 to 182,201 newtons (24,395 to 40,960 lbf) in a posterior bite, compared to the 18,216 newtons (4,095 lbf) bite force for the largest confirmed great white shark, and 7,495 newtons (1,685 lbf) for the placoderm fish Dunkleosteus. In addition, Wroe and colleagues pointed out that sharks ...
The shark had been coaxed into biting a custom-made "bite meter" as part of an experiment to measure mako bite force. The strongest bite recorded during the experiment was roughly 3,000 lbs. of force, or roughly 13,000 newtons. [21] Its endothermic constitution partly accounts for its relatively great speed. [22]
The average shark bite can generate up to 40,000 pounds of pressure per square inch; however, your odds of getting attacked and killed by a shark are only 1 in almost 3.5 million.
"Armed with bite force meters, biomedical imaging technology, and state-of-the-art super slow-motion cameras, they aim to capture and analyze shark bites in unprecedented detail." Shark Week 2024 ...
A 2007 study from the University of New South Wales in Sydney, Australia, used CT scans of a shark's skull and computer models to measure the shark's maximum bite force. The study reveals the forces and behaviours its skull is adapted to handle and resolves competing theories about its feeding behaviour. [ 108 ]
The bull shark's caudal fin is longer and lower than that of the larger sharks, and it has a small snout, and lacks an interdorsal ridge. [12] Bull sharks have a bite force up to 5,914 newtons (1,330 lbf), weight for weight the highest among all investigated cartilaginous fishes. [17]
The cookiecutter shark (Isistius brasiliensis), also called the cigar shark, is a species of small squaliform shark in the family Dalatiidae. This shark lives in warm, oceanic waters worldwide, particularly near islands, and has been recorded as deep as 3.7 km (2.3 mi).
