🧠 The Daily Fact #17

Sea cucumbers have a bizarre defense mechanism: they eject their internal organs when threatened. This process, called evisceration, might look like a catastrophic injury, but the sea cucumber is remarkably resilient. It can regenerate its organs within a few weeks, leaving predators baffled and hungry. Additionally, their sticky, expelled guts can entangle attackers. Sea cucumbers are vital for ocean ecosystems, too—they clean up debris on the seafloor by feeding on organic matter and recycling nutrients, acting like the underwater equivalent of vacuum cleaners.
