In August 2025, a paper published in the journal Frontiers in Marine Science suggested that ocean acidification could negatively impact a shark's most useful tool: their teeth. We speak with the papers lead author, Max Baum, about this research, and what the findings could mean for the sharks of tomorrow. Plus we take a deep dive into the wonders of shark teeth, and meet a decidedly unbothered tiger shark named Farida.

You can read the paper we discuss in this episode here: Simulated Ocean Acidification Affects Shark Tooth Morphology
