Sharks possess numerous teeth, not a fixed amount, and the number varies greatly depending on species, age, and tooth loss. Unlike mammals with a single set of permanent teeth, sharks have continuous tooth replacement throughout their lives. Their teeth are arranged in multiple rows, and when a tooth is lost or damaged, another moves forward to replace it. This conveyor-belt system ensures a consistently sharp bite, crucial for their predatory lifestyle. Some species may go through tens of thousands of teeth in their lifetime.
This continuous tooth replacement is a significant evolutionary adaptation, contributing to sharks’ success as apex predators. A constant supply of sharp teeth allows for efficient prey capture and consumption, providing a clear advantage in the marine food chain. The study of shark dentition provides valuable insights into evolutionary biology and the diverse adaptations within the shark family. Furthermore, the unique structure and composition of shark teeth have even inspired materials science research, with potential applications in developing strong and durable materials.
