Fun Facts:

  • Also known as the Asian Shore Crab and as their name suggests, these crabs were introduced to the east coast of the United State, where they have become an invasive species, but are originally native to shorelines in the western Pacific ocean
  • Pacific shore crabs were first sighted on the east coast in 1988 off the New Jersey coastline
  • This species is problematic in areas it has become invasive due to its ability to outcompete native species like mud crabs, and its predation of economically significant species like blue mussels
