How many speartooth sharks are left in the world?

There is no definitive answer to this question as the speartooth shark population is not known with certainty. However, the International Union for Conservation of Nature (IUCN) lists the speartooth shark as "vulnerable" due to overfishing and habitat loss. The IUCN estimates that the speartooth shark population has declined by 50% or more over the past 75 years.
