The number of teeth and their function can vary widely between species, with some dolphins having over a hundred teeth in their jaws, while the narwhal has two functional teeth in its upper jaw which grow into long tusks in males. The tusk is used in feeding, navigation and mating and contains millions of sensory pathways, making it the most ...
The canine teeth are able to withstand the tremendous lateral pressures from chewing. There is a single cusp on canines, and they resemble the prehensile teeth found in carnivorous animals. Though relatively the same, there are some minor differences between the deciduous (baby) mandibular canine and that of the permanent mandibular canine.
Animals where this occurs include antelopes, musk-deer, camels, horses, wild boar, some apes, seals, narwhal, and walrus. [6] Male dogs have larger canines with different contour than do females. [7] Humans have the proportionately smallest male canine teeth among all anthropoids and exhibit relatively little sexual dimorphism in canine tooth size.
The anterior teeth were almost perpendicular to the jaw and symmetrical, whereas the posterior teeth were slanted and asymmetrical. [63] Megalodon teeth can measure over 180 millimeters (7.1 in) in slant height (diagonal length) and are the largest of any known shark species, [29]: 33 implying it was the largest of all macropredatory sharks.

Creodonta ("meat teeth") is a former order of extinct carnivorous placental mammals that lived from the early Paleocene to the late Miocene epochs in North America, Europe, Asia and Africa. Originally thought to be a single group of animals ancestral to the modern Carnivora , this order is now usually considered a polyphyletic assemblage of two ...
The animal kingdom boasts some incredibly long lifespans that far exceed the average human's. While humans may have an "absolute limit" of 150 years, this is just a blink of an eye compared ...
The pliosaurids had large, conical teeth and were the dominant marine carnivores of their time. During the same time, approximately 160 million years ago, the Cryptoclididae were present, shorter species with a long neck and a small head. [55] The Leptocleididae radiated during the Early Cretaceous. These were rather small forms that, despite ...
