these long teeth. About one-third of the tusk is in the animal's skull (头骨). The tusk has a nerve (神经) running down its center. This makes it similar to your teeth. Once you lose a tooth, you will never grow a new one.

Elephants use their tusks to protect themselves, lift things, dig water and gather food. But losing the tusk will not kill them. The way in which they lose the tusk is what matters. Usually, people get tusks by culling (限量捕杀), which means killing old and weak elephants. They also take tusks from the elephants that have died naturally.

However, these sources aren't enough to keep up with the demand for ivory. Therefore, some poachers (偷猎者) kill healthy elephants and cut their faces open to remove the tusks. About 27,000 elephants are killed by poachers each year, according to National Geographic.

As a result of poaching, some African elephants gradually evolved (进化) without tusks, which has allowed them to survive. In Mozambique, about 90 percent of African elephants were killed for their tusks and meat from 1975 to 1992, National Geographic reported.

Scientists found that about a third of younger females—the generation born after 1992—never developed tusks.
