This is an episode that first aired in 2018 and then again in the thick of the pandemic in 2020. Why? Because though Horseshoe crabs are not much to look at, beneath their unassuming catcher\\u2019s-mitt shell, they harbor a half-billion-year-old secret: a superpower that helped them outlive the dinosaurs, survive all the Earth\\u2019s mass extinctions, and was essential in the development of the COVID vaccines. \\xa0And what is that secret superpower? Their blood. Their baby blue blood.\\xa0\\xa0And it\\u2019s so miraculous that for decades, it hasn\\u2019t just been saving their butts, it\\u2019s been saving ours too.
\\nBut that all might be about to change.\\xa0\\xa0
\\nFollow us as we follow these ancient critters - from a raunchy beach orgy to a marine blood drive to the most secluded waterslide - and learn a thing or two from them about\\xa0how much we depend on nature and how much it depends on us.
