The Astacidae : Evolutionary Resilience and Modern Challenges
The are a family of freshwater crayfish native primarily to the Northern Hemisphere, particularly Eurasia and western North America. Often recognized as the "noble" representatives of the infraorder Astacidea , they are distinguished from their Southern Hemisphere counterparts (Parastacidae) by specific morphological traits and a unique evolutionary history. While they have historically served as vital components of aquatic ecosystems and cultural culinary traditions, modern Astacidae populations face severe threats from invasive species and disease. Biological and Morphological Profile astacidae
