As the cargo director on the maiden voyage of the S.S. Buoyant, you’ve agreed to transport several tanks containing the last specimens of an endangered fish species to their new aquarium. Unfortunately, the boat is battered by a fierce storm, throwing your precious cargo overboard. Can you get the fish to safety and save the day?

This TED Ed riddle by Steve Wyborney, with animation by Artrake Studio, focuses on prime numbers and divisibility. It also uses a table to visualize the data and solve the riddle.
