Chapter 1: The Apex Predators

The oceanic orca (Orcinus orca) and the great white shark (Carcharodon carcharias) are both dominant predators within their marine environments. These species sit at the pinnacle of the food chain, having few natural threats to their existence—humans being the primary exception. However, intriguing incidents of orca attacks on these formidable sharks have been documented, and researchers have noted a concerning decrease in the shark population along South Africa's coast in recent years.

This aerial footage represents a pivotal moment in understanding these interactions. Scientists in South Africa undertook a study to observe orca behavior from the skies. They aimed to capture the hunting strategies of these marine mammals, ultimately leading to groundbreaking footage that challenges existing perceptions of marine ecosystems.

On May 16, researchers successfully recorded an orca ambush on sharks in the vibrant blue waters of the Indian Ocean near Mossel Bay. The footage reveals two orcas swimming close to a stranded shark. Suddenly, a third orca emerges from below to engage the predator, turning the water a striking crimson.

This remarkable video captures the unprecedented moment of orcas attacking great white sharks, providing valuable insights into predator dynamics.

“This behavior has never been documented before, especially from an aerial perspective,” explains Alison Towner, a marine biologist from Rhodes University, a co-author of the study published in the journal Ecology. The researchers meticulously analyzed the orcas' attack strategy, revealing a highly coordinated approach.

The orcas expertly flipped the shark onto its side, targeting its vulnerable underbelly. Eventually, the shark vanished into the depths, leaving its liver to float to the surface. The researchers noted that the orcas displayed teamwork—one distracts the shark while others prepare for the attack. Remarkably, they managed to kill at least three sharks in a single hour using this method.

Section 1.2: Identifying the Predators

One orca, identified as “Starboard,” has been linked to prior shark fatalities along the coast. This orca, along with a companion named Port, is believed to have hunted together in the area. According to David Hurwitz, a local boat operator specializing in cetaceans and sharks, “I first encountered Starboard in 2015. Alongside Port, they are suspected of killing seven sharks in False Bay. Witnessing them kill a copper shark in 2019 was astonishing, but this video reveals an entirely new level of predatory behavior.”

The emergence of these hunting tactics raises questions about the implications for the local shark population.

Chapter 2: Implications for Shark Populations

Two separate videos captured the orcas' attacks—one from a drone and another from a helicopter. Both suggest a possible connection between the two hunting events. Observers noted sharks fleeing the area just minutes before the first video was recorded. In total, the footage documented ten sharks on that day, and none were seen in Mossel Bay for several weeks thereafter.

This compelling video showcases orcas in action, providing crucial evidence of their predatory skills against great white sharks.

Experts emphasize that the orcas' hunting technique is not only effective but also sophisticated. There are growing concerns that if more predators adopt similar strategies, it could pose a significant threat to the local white shark populations.
