Hear from Deborah Cramer, author of The Narrow Edge: A tiny bird, an ancient crab, and an epic journey, who explains how the threatened red knot is an omen for how devastating ocean acidification can be.
A changing climate could cause some serious problems for the rufa red knot, which we recently listed as a threatened species.
One might think a creature named the horseshoe crab would be naturally lucky–and in some ways it is. The prehistoric throwback has retained its basic physiology for around 350 million years, so it’s already far outlasted our own species on an evolutionary scale. Evolved as it may be, its luck has been challenged along the shores of the Delaware Bay.
