Put your claws up, Crustacean Nation — this Crabstravaganza is going global.

Crab Week is an annual marine science shell-ebration that highlights the biodiversity of the Hudson River through our friendly neighborhood decapods. Crabs are an important part of our local ecosystem and play a vital role in supporting a healthy and balanced marine environment. 

Hudson River Park’s 400-acre Estuarine Sanctuary is home to eight species of local crabs, and this week they’re scuttling onto center stage.

As NYC welcomes visitors from around the world for an extraordinary summer of international events, Crab Week is looking beyond our own estuary to explore some of the ways crabs connect ecosystems, cultures and communities across the globe.

Get ready for crabtivating facts you can share at parties, crabtivities for the whole family and fun ways to connect our local crabs to the wider world. Be sure to follow along all week on Instagram, Facebook and X!
