Some New York subway riders found themselves with an unexpected fellow passenger on the D train.
An opossum curled up underneath a seat near the train's heating duct.
The New York Times reports the animal apparently got on at Coney Island in Brooklyn.
The station there is above ground.
The subway car was evacuated.
When the critter started snarling at police officers, animal control experts were called in.
A transit spokesman says it's the first time anyone can remember a wild animal in the subway system.
