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.
A young adult horse will have teeth which are 4.5-5 inches long, with the majority of the crown remaining below the gumline in the dental socket. The rest of the tooth will slowly emerge from the jaw, erupting about 1/8" each year, as the horse ages.
In many species the canine teeth in the upper or lower jaw, or in both jaws, are much larger in males than in females, where they are sometimes hidden or completely absent. Animals where this occurs include antelopes, musk-deer, camels, horses, wild boar, some apes, seals, narwhal, and walrus. [6]
The two record holders for longest and heaviest recorded African bush elephant tusks are around 3.49 metres (11.5 ft) long measured along the outside curve, and 107 kilograms (236 lb) in weight respectively, while the longest and heaviest Asian elephant tusks are 3.26 metres (10.7 ft) long and 73 kilograms (161 lb) respectively.

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 with ...
The molar teeth of Palaeoloxodon species typically show a "dot-dash-dot" wear pattern, [16] with the enamel folds concentrated into a major central structure at the midline of the tooth, which are flanked by smaller folds on either side, and the crowns of the tooth are generally proportionally narrow. [17]
While the form of the teeth themselves is not affected by postcanine megadontia, the ratio of molar teeth volume to total teeth volume is dramatically larger in specimens with postcanine megadontia compared to their modern human counterparts, an adaptation that shows signs of evolutionary convergence when compared to the form and function of ...
