8 Facts about the Atlantic Horseshoe Crab
Bex Hainsworth
1.) They are not actually crabs, but faux-crustaceans,
aquatic scorpions; arthropods with arachnid-kin.
2.) Triassic reverberations, they are their own ancestors,
unchanged fossils, 230 million years in the making.
3.) Called Limulus Polyphemus, after the Odyssean cyclops,
but unborn embryos have nine eyes and a sense of irony.
4.) Liminal in existence, they live in the gaps between land
and sea: the brackish, the shallows, the world’s edges.
5.) Their distinctive carapace – armour, disguise, barnacled
island – is regularly moulted, left behind like pottery.
6.) Females are larger than males, often scarred from mating,
when suitors cling to the rafts of their bodies for months.
7.) Each spring, they are spades, digging nests in the same sand
where they were spawned; 64,000 eggs shine like blue pearls.
8.) Their blood is used in medical research. We claim catch and
release, hands slick, harvesting the sea in search of immortality.
