Sleeper sharks feed deep in the South China Sea

Rare footage reveals Pacific sleeper sharks feeding at a depth of over 3,000 feet in the South China Sea, expanding their known range. Scientists observed the sharks feeding on a dead cow dropped into the ocean, documenting a hierarchical feeding behavior among the predators. The sharks, typically found in colder waters, were all female in this instance. This discovery, made near Hainan Island, provides new insights into the species' habitat and behavior, as well as potentially indicating a nursery ground for the sharks.
