• Lancetfish consume a high diversity of poorly known micronekton prey.
• Diet varies in a predictable way across the North Pacific Subtropical Gyre.
• Unique prey and cannibalism may help explain prevalence of lancetfish in North Pacific.
• Lancetfish are useful biological samplers of midwater prey communities.
