In this second episode of our Swarms Minisode Series, Laura and Katy dive into a lesser-known swarm behavior: shark aggregations. From 1,400 basking sharks off New England to over 15,000 spinning sharks off the Florida coast, this episode explores the science (and chaos) behind why some of the ocean’s most feared predators travel in giant, synchronized groups.
🦈 Why do basking sharks—normally loners—form feeding spirals?
🌊 What caused 15,000 blacktip and spinner sharks to swarm near Florida in 2013?
🧲 Could Earth’s magnetic fields (or sonar) influence shark migration patterns?
🎯 And do predators swarm for the same reasons as prey?
This minisode is a fast, fascinating look at how even apex predators can get caught up in the group dynamic—and what it means for scientists, beachgoers, and Shark Week fans alike.
👉 This is episode 2 of 6 in our Swarms series—short, science-packed episodes exploring how and why animals move as one.
