A vast whale graveyard + Zombie sea cucumbers
Summary
This Science Friday episode explores two marine discoveries. First, Dr. Nick Pyenson discusses a vast 745-mile whale necropolis in the Indian Ocean, detailing how these "whale superhighways" accumulate ancient remains and support active ecosystems. Later, researchers Rachel Sippler and Sarah Jobson explain their finding of "zombie" sea cucumber parts that survive for years after detachment, maintaining immune function and neural responses without a host body.
