Introduction - The Remarkable Horseshoe Crab

What do you know about horseshoe crabs? Why are they important to people and birds? Why are volunteers traveling to the Delaware Bay to count crabs?


Symone Johnson:

The remarkable Horseshoe crab - they are called “living fossils” because they have changed very little in the last 450 million years. Although they are called crabs, they are more closely related to spiders and scorpions, and their annual mating migration is an incredible sight to see.

The Ocean Today crew documented their yearly spawning ritual on the beaches of Delaware Bay, where thousands come ashore during the full moon in late Spring.

Every year, volunteers travel to the Atlantic coast in May or June to count crabs and birds.
