Invertebrates of the region are now featured under SAIN Animals and Plants of the Region. Invertebrate populations in the Southeast are global center of biodiversity. More importantly, invertebrates are a critical component of many healthy ecosystems. Reflecting the importance of invertebrates, SAIN has developed content about both freshwater and terrestrial invertebrate taxonomic orders including gastropods such as snails, decapods such as crayfish, and mollusks such as freshwater clams.
