Invader ID ProjectIf you’ve ever looked underneath a dock, you’ve probably noticed that it is covered with living things! This group of organisms, known as a fouling community, contains a wide variety of invertebrate animals, algae, and bacteria. Through Invader ID, you can help us to track changes in fouling communities and look for new occurrences of invasive species. With your help, we’ll be able to track fouling communities in more places, and hopefully see early warning signs of environmental changes.
