There's a new invasive species in New York State, and the Department of Environmental Conservation is asking for the public's help.

It's an unfortunate reality that New Yorkers are being constantly barraged by non-native animals that seem intent on causing harm to the local environment. While the Hudson Valley, NY is currently battling spongy moth caterpillars that are literally causing poop to fall from the sky, another troublemaker has been found in the Hudson River.

"Meet the Mitten Crab (Eriocheir sinensis)", began a recent post from the New York State Department of Environmental Conservation (NYS DEC). The crab, native to Asia, has been spotted in both the Long Island Sound as well as the Hudson River, and the NYS DEC has a specific message for resident who come across the crustacean.

NYS DEC Says to Freeze Mitten Crabs

"If you see a Mitten Crab, remove it from the environment and freeze it", the NYS DEC requested (below). "Make sure to take identifying photos and note your precise location", they continued. Photos and reports can be sent to isinfo@dec.ny.gov. Identifying a mitten crab can be easy thanks to one telltale sign.

How to Identify Mitten Crabs in New York State

Adult mitten crabs, the NYS DEC says, have claws that appear furry (thus the name "mitten" crab). While younger crabs do not have this unique characteristic, all mitten crabs have a notch in their shell between their eyes, as well as "lateral spines" on each side of their body.
