One of the ocean’s top predators has met its match.
Filipa Samarra could hear the pilot whales before she could see them. In 2015, out on the choppy waters off of southern Iceland, Samarra and her research team were eavesdropping on a group of killer whales. She listened as they pipped, squealed, and clicked when suddenly her ears were filled with high-pitched whistling. “Then the killer whales just went silent,” says Samarra, a biologist and the lead investigator of the Icelandic Orca Project. As the whistling grew stronger, a group of pilot whales came into view, and the killer whales seemed to turn and swim away.
“It’s quite unusual because the killer whale is this top predator,” says Anna Selbmann, a doctoral candidate at the University of Iceland who is supervised by Samarra. “It’s very unusual that they’re afraid of anything—or seemingly afraid.”
