Weekend Update: October 9-11

Our legendary 2015 late season whale watching continues to impress, with this weekends sightings including resident killer whales, humpback whales, as well as transient killer whales.

On Friday the Sea Lion went out on a high seas adventure, looking to find some of our Southern Resident killer whales just to the south end of the San Juan. We marveled at some members of L Pod including L72 Racer and her son L105 Fluke as they surfed in the waves around our vessel. We also enjoyed views of some bald eagles as we made our way back to Friday Harbor.

On Saturday we headed north into the waters around Spieden Island searching for humpback whales, the fifth largest whale in the world, here in the North Pacific growing up to 50 feet long! These whales, members of a group known as the mysticetes (translates to "mustached whales"), have baleen in their mouths instead of teeth. Baleen is made out of keratin, the same stuff that our fingernails and hair is made out of. The whales use these baleen plates as filters, taking giant mouthfuls of water containing tiny fish and shrimp-like creatures called krill, and then, using their tongues, pressing the water out through their baleen leaving a giant mouthful of food. We enjoyed watching the humpback surfacing through the classic Pacific Northwest mist.

On Sunday we again headed north, but this time to the Strait of Georgia in search of some reported transient killer whales. These orcas are marine mammal eaters, hunting seals, sea lions, porpoises, dolphins, and whales. Because their prey is incredibly aware of their surroundings, these whales tend to be very quiet at the surface and usually travel in small groups of about 5-6 animals. Never say usually with transients!! We were treated to watch a group of about 9 animals as they leisurely traveled south, playing in the currents and resting.

Another great weekend for the books, October continues to be just incredible!
