One of the biggest threats to the San Francisco Bay's estuarine community is a tiny crab with furry claws. The Chinese mitten crab may sound benign, but its voracious appetite and escalating population is compromising the ecology of this once-thriving system. Invasive Aquatic and Wetland Animals investigates the threat of the Chinese mitten crab and many other invasive species. The book explains how these creatures are introduced, how they affect aquatic systems, and what is being done to contain them.
