Close-up videos of sharks foraging on other live sharks are rare, especially when it comes to footage of the entire duration of an event.
Our goal was to present an in-depth analysis involving a Galapagos shark, Carcharhinus galapagensis, foraging on a whitetip reef shark, Triaenodon obesus.
A frame by frame video examination was used to highlight the different aspects of this bout.
Several behavioral characteristics, including the somewhat cryptic approach, the extensive shaking once the Galapagos shark had the whitetip reef shark between its jaws, and devouring tail-first, stand out in this event.
The entire act appeared very smooth, indicating that this bout, or at least parts thereof, may represent a common hunting strategy for Galapagos sharks.
