A "stowaway" was inside a shipment of electronics that arrived in Florida, from Puerto Rico.
The Florida Fish & Wildlife Conservation Commission says the snake is either a Puerto Rican boa or a Mona Island boa; it's tough to tell the difference between the two without a DNA test.
Both snakes are endangered in Puerto Rico.
FWC arranged for the creature's safe trip home. This was the first time the "Exotic Species Hotline" was used to detect a non-native species coming into the mainland.
The hotline number is 1-888-IVE-GOT1.
