Join Maria Mitchell Aquarium staff to learn how to identify the European green crab (Carcinus maenus), an invasive species that threatens Nantucket's native species and habitats! We will compare these species to local crab species and determine their biological sex. This is a great opportunity to learn about our annual Nantucket Green Crab Derby and all of its events! 

This program will meet at the MMA Aquarium, 32 Washington Street, Nantucket MA.
