Flights at John F. Kennedy International Airport were delayed shortly on Wednesday when about 150 diamondback terrapin turtles were spotted crossing a runway, Reuters reported.

The reptiles were trying to get to the other side of the runway to lay eggs on the sandy shores of the Jamaica Bay Wildlife Refuge, which borders the airport.

Ron Marsico, a spokesman for the Port Authority of New York and New Jersey, which oversees operation of the region's airports, said pilots from Jet Blue and other airlines halted their flights to let the expectant reptiles pass.

"Flight delays attributed to turtles were minor, about 15 minutes or so," he said.
