The creature’s jagged teeth come from the fact that sharks replace their teeth so frequently1.

Shark teeth are not permanent teeth. They have only one fixed row. Instead, they have multiple rows. Except for the teeth that are being used, the remaining rows are spare, and sharks will also replace their teeth as they grow. , generally a shark will replace thousands of teeth, and the shark's teeth will be uneven.

The uneven characteristics of the fish’s teeth are also related to its unique way of hunting. Shark teeth are serrated, a shape that helps them bite and tear apart prey quickly. The unevenness of a shark's teeth also increases the stability of its bite, allowing it to better grip and engulf prey. This unique tooth structure is one of the important factors that make sharks become apex predators.
