Incredible video of horseshoe crabs mating at Greenwich Cove

The biological genus is limulidae – commonly known as horseshoe crab – which is arguably the ugliest living creature on the planet.

But their resistance to all kinds of biological threat is legendary, and their survival since pre-historic times is a puzzle to scientists.

For several months a year in New England, they breed along our shores. At this time of the year, you can spot them in abundance, such as this video along the shore near Old Greenwich Yacht Club will attest.
