Many plants and animals make the coastline of Massachusetts their home. For animals, the shoreline may provide a place to rest, nest, feed, or reproduce. For plants and seaweeds, the beach or nearshore area affords a place to root, shoot, spread, and replicate. With the wealth of species out there, identification can be a challenge. But wouldn’t it be nice to name that seabird or maybe even finally be able to identify (and avoid) that pesky poison ivy? Here are a few links to help you identify some of the more common animals and plants at the shore.
