An angler in Costa Rica caught a rare 6-foot-6 nurse shark with a bright orange body and white eyes, the first documented case of “xanthism” in the species.

The catch, made in Tortuguero National Park, marks the first recorded orange shark in the Caribbean Sea, according to Marine Biodiversity researchers.

The pigmentation condition gives animals yellow or golden tones, making this sighting a unique scientific discovery, USA Today has reported.
