BUT people need to know
- how
to identify the Chinese mitten crab, and

The
Chinese mitten crab (Eriochier sinensis) is native
to East Asia where it is valued as food. It spends most of its
life in fresh water and migrates to the sea to reproduce. It
is the only crab in fresh water and is characterized by the
fuzz on its claws.

• If you find a crab without fuzzyclaws, it is NOT likely
to be a Mitten Crab

in color
• No swimming legs. This crab has eight sharp-tipped walking
legs
