arsen [322]

The Elephant Maximus is the species that was introduced and later became extinct on Maguindanao.

Extinction occurs as all members of a species die, and therefore the species disappears. This includes complete extinction or extinction of the species in a specific zone.

In the case of the Elephant Maximus, which is known as the Asian Elephant, this species became extinct in a region known as Maguindanao in the Philippines.

This partial extinction occurred as the elephants from this zone were taken to Sabah in Malaysia from the 13th century to the 16th century. This occurred because the Sultans of this region considered this elephant to be a valuable and even sacred animal.
