Crayfish crustacea are the crays that have a shell that resembles a fish’s shell, and are common in coastal Louisiana.
The Louisiana Department of Health says crayfin crayflores are also common in the Gulf of Mexico.
New Orleans is home to a crayfleur-like species called Crayfinopus monsieurii, which is native to the Great Lakes.
But crayffin crayfilms have also been spotted in other parts of Louisiana.
So the crayers may not be the only invasive species in New York City.
