Do Orcas Hunt for Seals or Sea Lions in California's North Coast?
Orcas, also known as killer whales, are apex predators known for their intelligence and hunting skills. Along California's North Coast, orcas are known to prey on various marine mammals, including seals and sea lions.
Seal and Sea Lion Populations
The North Coast of California boasts large populations of both harbor seals and California sea lions. These animals congregate on rocky shorelines, beaches, and offshore islands, making them accessible targets for orcas.
Hunting Techniques
Orcas employ diverse hunting strategies to capture their prey. They often use echolocation to locate seals and sea lions underwater and form pods to engage in cooperative hunts. Orcas have been observed using techniques such as spy-hopping, porpoising, and tail-slapping to separate seals from their colonies and weaken their prey.
Seal vs. Sea Lion Preference
While orcas are known to hunt both seals and sea lions in California's North Coast, their preference may vary depending on availability, size, and energy content. However, studies suggest that orcas may have a preference for hunting seals due to their smaller size and higher blubber content compared to sea lions.
