Moctezuma, an adult male killer whale from a unique pod, has been identified as one of the orcas involved in hunting activities. These killer whales have shown remarkable abilities in hunting whale sharks, which are known to be the largest fish in the world.
Killer whales typically prey on marine mammals, turtles, and fish. However, this particular pod in the Gulf of California seems to have developed specialized skills for targeting whale sharks. These massive creatures can grow up to 18 meters long and are often found feeding at aggregation sites in this region.
Researchers in Mexico have documented four separate incidents where orcas from this pod engaged in collaborative hunting techniques to target whale sharks. By focusing their attacks on specific areas like the pelvic region, they were able to cause bleeding and gain access to nutrient-rich organs like the liver.
Erick Higuera Rivas, a marine biologist involved in studying these events, highlighted how individual orcas within this specialized pod displayed coordinated efforts during these hunts. Moctezuma was present during three out of four recorded events, indicating his significant role within this group.
The predation events took place between 2018 and 2024 in southern Gulf of California waters and were captured through images and videos taken by both scientists and members of the public. By analyzing distinctive features like dorsal fins and scars, researchers were able to identify individual orcas participating in these hunts.
The presence of Moctezuma alongside a female orca during one event suggests possible familial ties within this unique pod specializing in hunting whale sharks. These findings shed light on how killer whales adapt their hunting strategies based on available prey species.
