The Chesapeake Bay -- the largest estuary in the U.S. -- is an incredibly complex ecosystem that includes important habitats and food webs. The Bay itself, its rivers, wetlands, trees and land all provide homes, protection or food for complex groups of species. Fish of all types and sizes either live in the Bay and its tributaries or they use the waters as they migrate along the East Coast. Young crabs hide from predators in underwater grasses, while oysters filter water as they feed on plankton. The intertwined combinations of relationships are countless. The physical processes that drive the Chesapeake Bay ecosystem sustain the many habitats and organisms found there. Complex relationships exist among the living resources of the Bay watershed. Even the smallest of creatures plays a vital role in the overall health and production of the Bay. Use the map below to learn more about the Chesapeake Bay ecosystem.
