🎬 Reel Script (English, ~1.5 minutes)

"Dinosaurs went extinct millions of years ago… but there’s one creature that is even older than dinosaurs, still alive today, and still protecting humanity! This is the Horseshoe Crab — a living fossil that has survived for more than 450 million years.

Its blood is not red like ours, but bright blue. Why? Because instead of iron, it carries copper. But the real miracle is hidden inside this blood: special cells that can instantly detect dangerous bacterial toxins. Scientists carefully collect some of this blood and extract a substance from it. That substance is then used to test every new vaccine, every injection, every IV fluid, to make sure they are safe for humans. Without this test, modern medicine would be far more dangerous.

The process is delicate: crabs are caught, a portion of their blood is taken, and then they are released back into the ocean. Sadly, some don’t survive, which is why researchers are now working on synthetic alternatives — so that these ancient creatures can be protected. #HorseshoeCrab #BeforeDinosaurs #BlueBlood #LivingFossil #ScienceReels #AncientCreature #MedicalScience #VaccineSafety #BiologyFacts #OceanMystery #ScienceDiscovery #AmazingNature #Evolution #ProtectNature #AncientLife
