[37] Shark teeth form within the jaw move outward in rows until they are eventually dislodged in a manner similar to a conveyor belt. [38] Their scales, called dermal denticles, and teeth are homologous organs. [39]

  3. Bite force quotient - Wikipedia

    en.wikipedia.org/wiki/Bite_force_quotient

    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. [ 1 ]

  4. Durophagy - Wikipedia

    en.wikipedia.org/wiki/Durophagy

    There is the presence of calcified strengthened cartilaginous jaws, calcified struts within the jaws and a lever 'nutcracker' system that amplifies the force of the jaw adductor muscles. The fusion of the palatoquadrate and mandibular symphysis, a restricted gape and asynchronous activation of the jaw adductors are key elements in the ...

    Although sharks rarely bite humans, the tiger shark is reported to be responsible for a large share of fatal shark-bite incidents, and is regarded as one of the most dangerous shark species. [61] [62] They often visit shallow reefs, harbors, and canals, creating the potential for encounter with humans. [5]

    Osteichthyes is divided into the ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii). The oldest known fossils of bony fish are about 420 million years ago, which are also transitional fossils, showing a tooth pattern that is in between the tooth rows of sharks and bony fishes.

  9. Helicoprion - Wikipedia

    en.wikipedia.org/wiki/Helicoprion

    Helicoprion is an extinct genus of shark-like [1] eugeneodont fish. Almost all fossil specimens are of spirally arranged clusters of the individuals' teeth, called "tooth whorls", which in life were embedded in the lower jaw. As with most extinct cartilaginous fish, the skeleton is mostly unknown.
