What Feeds Beneath

While on an expedition at Todos Santos in south Baja California, Mexico, Alejandro Prieto was searching for big predators—such as marlins, sharks, or tuna—feeding on sardine bait balls, but instead he found this Hawaiian petrel feeding on crustaceans. “Luckily I was able to capture the moment it submerged its head to feed on the tiny food source,” Prieto writes.
