A pod of transient orcas, known as Bigg’s killer whales, appeared near the Ballard Locks in Seattle on Monday evening. Observers recorded the whales in the water just after 5 p.m. as they moved through the area.
Marine scientists explain that these whales likely entered the vicinity to hunt seals and sea lions. The presence of these predators near the locks is viewed as a positive sign for local salmon populations. By controlling the number of seals and sea lions that often prey on migrating salmon, the orcas provide an important ecological service.
This interaction highlights the interconnected nature of the Salish Sea ecosystem. When orcas visit these specific locations to hunt their preferred marine mammals, they help balance the local food chain. This creates better conditions for the salmon to migrate safely through the waterway.
The sighting drew attention from locals who gathered to watch the marine mammals in action. Researchers continue to track these pods to learn more about their hunting patterns and impact on the regional environment.
