i donno what u meant by this Qn..
Tusks are large teeth coming out of their upper jaws...
Although both African elephant sexes have tusks, there are large differences in size and weight. Typically, the male tusk has a larger circumference in relation to its length, is stouter, and is much heavier.
Asian elephant elephants have tusks; approximately 40-50 percent of male Asian elephants are tuskless.
The tusks present at birth are only milk teeth which fall out after around one year of age (approximately 5 cm long). The permanent tusks begin to protrude beyond the lips of an elephant at around 2-3 years of age, and will continue to grow throughout its life. Were and elephant's tusks able to grow long enough they would be in the shape of a spiral (similar to the extinct woolly mammoth), because the tusk typically follows a sinusoidal curved growth pattern. The growth rate of tusks is at approximately 15-18 centimeters per year.
