Summary: Every spring, millions of horseshoe crabs flock to the shores of the Delaware Bay. As they have done since before the time of the dinosaurs, the crabs lay their eggs in the sand. Meanwhile, flocks of different types of birds make their way to these same shores as they migrate to the Arctic. They are hungry and weak on their arrival, and the horseshoe crab eggs are packed with fat and protein. They feast on the eggs, sometimes doubling their body size in just a few weeks. Many eggs remain, though, buried in the sand until the birds have continued on their way. Then, tiny crabs the size of ladybugs hatch and swim into the sea. People come from all over to watch and study this chapter in the lives of the horseshoe crabs and the birds. Grades K-4.

Pros: Having spent many summers in Cape May, New Jersey, I can remember finding the remains of horseshoe crabs on the beach. I never suspected the fascinating story behind these ancient looking creatures. This book makes science accessible to even the youngest students. The story is clearly written and beautifully illustrated, and the end material gives more interesting information. Readers will want to study the labeled drawings on the end papers.

Cons: I didn’t really understand the page that simply said, “It’s happening!” which seemed to connote an exciting event that wasn’t quite clear to me.
