How do elephants get there stretch marks?

Elephants develop stretch marks primarily due to rapid changes in their skin as they grow, gain weight, or during pregnancy. The skin of elephants is thick and elastic, but when it is stretched too quickly, the underlying collagen fibers can tear, leading to the formation of stretch marks. These marks are often more noticeable in areas where the skin is more mobile or where fat accumulates. Over time, the color of these marks can fade, but they remain a permanent part of the skin.
