Due to poaching, it is becoming more and more difficult to observe an elephant with big tusks in its natural habitat. Such elephants are called "tuskers". Tusks grow throughout the elephant's whole life, which is why they are the domain of aged males. A relatively large number of "tuskers" live in the Amboseli National Park in Kenya, where this photo was taken. Big tusks grow thanks to the micronutrients found there that support this growth.
