The annual spawning of the horseshoe crabs serves as a way to speak about the life cycle of this fascinating creature. As the crabs come to the shore, they ride the high tide to get far enough up on the beach for their eggs to be safest. Following the crabs are the shorebirds who are looking for a feast. Humans are coming too, scientists who study both the crabs and the birds. The horseshoe crabs begin laying their eggs, their bodies piled high at the edge of the shore, all trying to reach the sand to deposit their eggs. The scientists tag the crabs, allowing them a better way to study how these creatures live and where they travel. The eggs that survive the birds feasting start to grow and the adult crabs return to the sea. A few weeks later, the baby crabs hatch and make their way down the sand to the sea too.
Schnell has created a book that celebrates the horseshoe crabs and highlights not only their life cycle but their impact on the larger habitat as well. Tying the human scientific element into the book as well informs young readers that there are interesting natural studies happening all around them. The final pages of the book offer many additional details on the horseshoe crab and how they function in the food system. Readers will also find more resources on the crabs including websites and books to explore.
