An African elephant in Tanzania, with visible tusks. Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with narwhals, chevrotains, musk deer, water deer, muntjac, pigs, peccaries, hippopotamuses and walruses, or, in the case of elephants, elongated incisors.
When looking at an African elephant and an Asian elephant side-by-side, you can really tell the differences in their head shapes and tasks. African elephants generally have much larger tusks than ...
While male Asian elephants have tusks, female Asian elephants do not grow tusks. However, about 50% of the female population grows smaller incisors that sometimes protrude under the upper lip like ...
The elephants collapsed when the toxin impaired their motor functions and their legs became paralysed. Poaching, intentional poisoning, and anthrax were excluded as potential causes. [84] Elephants may also be host for a variety of parasites and bacteria such as Pasteurella, [85] Salmonella, Clostridium, [86] coccidian, nematode, and trematode ...
Elephantiformes is a suborder within the order Proboscidea. [1] Members of this group are primitively characterised by the possession of upper tusks, an elongated mandibular symphysis (the frontmost part of the lower jaw) and lower tusks, and the retraction of the facial region of the skull indicative of the development of a trunk.

The skull is proportionally short and tall, [3] with the premaxillary bones containing the tusks being flared outwards. The tusks have relatively little curvature, and are proportionally large, [6] and somewhat twisted, with the tusk alveoli (sockets) being divergent from each other at least in Pleistocene species. [3]
Although elephant tusks appear large today, the tusks of their ancestors were dramatically larger. Due to the large size of the tusks, and the fact that they were longer than the elephant’s head ...
