Asian elephants do not have this concern, as they live in more tropical and wet climates. The post Size, Tusks, and Ears: How African and Asian Elephants Differ appeared first on A-Z Animals .
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.
Both male and female African elephants have tusks that grow from deciduous teeth called tushes, which are replaced by tusks when calves are about one year old. Tusks are composed of dentin , which forms small diamond-shaped structures in the tusk's center that become larger at its periphery. [ 25 ]
The dominant, or "master" tusk, is typically more worn down, as it is shorter and blunter. For African elephants, tusks are present in both males and females and are around the same length in both sexes, reaching up to 300 cm (9 ft 10 in), [57] but those of males tend to be more massive. [58] In the Asian species, only the males have large tusks.
A hefty set of tusks is usually an advantage for elephants, allowing them to dig for water, strip bark for food and joust with other elephants. Now researchers have pinpointed how years of civil ...
Head of a male without tusks. The Sri Lankan elephant (Elephas maximus maximus) is native to Sri Lanka and one of three recognised subspecies of the Asian elephant.It is the type subspecies of the Asian elephant and was first described by Carl Linnaeus under the binomial Elephas maximus in 1758.

A larger tusk measuring 2.96 metres (9.7 ft) long and weighing 70 kilograms (150 lb) has been recorded, but this may belong to a forest-bush elephant hybrid. The average tusk size is uncertain due to measurements historically being lumped in with those of African bush elephants, but based on the sizes of the largest known tusks may be in the ...
The lower tusks are generally smaller than the upper tusks, but could grow to large sizes in some species, like in Deinotherium (which lacks upper tusks), where they could grow over 1.5 metres (4.9 ft) long, the amebelodontid Konobelodon has lower tusks 1.61 metres (5.3 ft) long, with the longest lower tusks ever recorded being from the ...
