Cameras attached to 42 white sharks provided around 112 hours of usable footage from Seal Island in South Africa and the Neptune Islands in Australia. A study in Wildlife Research uses these recordings to document hunting, exploration and rarely observed bodily functions.
Mouth movements and unusual encounters
The function of frequent brief mouth opening remains unclear. Recordings also show the investigation of inanimate objects. Additional diver videos document intestinal eversion and possible mobbing of a shark by southern bluefin tuna.
Insights with limited scope
The observed behaviours cannot all be interpreted as hunting. However, individual sequences and differing recording conditions also prevent general conclusions about their frequency across the population. The videos were recorded over several years; the publication year, 2026, is not the year of filming.
Haitauchen has also reported on a different camera study of young white sharks off New South Wales. The two studies should be considered separately.
