At 19 inches long, this rainbow trout caught in Alaska’s Togiak National Wildlife Refuge is unremarkable on the outside. What was found in its stomach, however, has researchers scratching their heads. When they opened up the fish, park biologists found nearly 20 half-digested shrews inside.
“[It is] an awful lot for one fish to put down,” fish biologist Mark Lisac told LiveScience.
The biologists caught the fish while placing radio transmitters in the Kanektok River as part of a study to understand fish movements.
