Off the Costa Rica’s east coast, sport fishers stumbled upon a highly unusual 6.6‑foot nurse shark exhibiting bright orange coloration—an unprecedented case of xanthism in this species. Even more extraordinary, the shark also displayed signs of albinism, including a lack of black in its irises. This rare combination, known as albino‑xanthochromism, has almost never been seen, previously documented only in a few other marine species like an Irish Sea ray. The shark was safely photographed and released.Editorial Staff
