As a whole, Atyidea was of small body size, and few widespread species, and 73% species were deficient of data or not evaluated in the Endangered Category. Given that it was an indispensable component of freshwater biodiversity or ecosystems, further studies on its ecobiological characteristics and conservation should be strengthened.展开更多
