Story highlights Marine biologists were filming sharks and coral when they encountered a "glowing" turtle

The turtle was green and red, and one scientist said it looked like a spaceship

(CNN) That's not a "Teenage Mutant Ninja Turtle" floating before your eyes. You're seeing the first biofluorescent reptile discovered by scientists.

While filming small sharks and coral reefs in the Solomon Islands in the South Pacific, marine biologists had a stunning encounter with a "glowing" sea turtle.

Scientists captured footage of a hawkbill sea turtle emitting neon green and red light. The discovery was made in late July by David Gruber of the City University of New York and his team. The footage was released for the first time on Monday.

Gruber, an emerging explorer for National Geographic, described the turtle as an alien spaceship when he initially saw it swimming in the water.
