Participate in the 2013 "Crab Watch"!
Help our research team track the predicted 2013 hermit crab migration in the US Virgin Islands, on St. John (and throughout the Caribbean!!)

Last year, thousands of crabs were observed migrating to the sea. On their trek from the mountains to the shore, they crossed streets, passed through parks, backyards, and other property. YOU can help us to determine when and where the crabs are headed!

Our research team is dedicated to understanding why these migrations occur -- with your help, we'll be able to observe and video this migration to better understand this amazing phenomenon.
