A study in the South China Sea unexpectedly documented eight Pacific sleeper sharks feeding on a cow carcass deployed 1,629 meters deep. This is the first recorded instance of the species in this region, challenging existing understanding of their range and habitat preferences. The sharks exhibited intriguing behaviors including queueing for food and eye retraction, with larger sharks showing more aggression. The discovery suggests a potentially larger, less understood population and abundant deep-sea food sources in the South China Sea.
