A world first! King penguins prey on fish in the dark sea.

A press release issued by the Atmosphere and Ocean Research Institute at the University of Tokyo on May 28, 2025, presented research findings that captured, for the first time in the world, king penguins hunting fish in the dark depths of the ocean. In this study, researchers successfully recorded the penguins’ hunting behavior at depths of over 100 meters by attaching small video cameras equipped with LED lights to the penguins.

The video logger used in this study was our product, the LoggLaw CAM. The LoggLaw CAM is a high-performance video logger designed to record animal behavior in detail, and it has been utilized in various research projects, including studies involving sea turtles, whale sharks, and bluefin tuna.

We are deeply honored that our product has contributed to such cutting-edge research. We will continue to develop products that contribute to the advancement of scientific research.
