On February 21, 2010, J and K pods were sighted in the San Juan Islands heading up towards Canada. Jeanne Hyde, Orca Adoption Program Manager, photographed a possible new calf swimming with Sequim (K-12) and Sekiu (K-22). Unfortunately, there was no chance to verify the presence of the calf as the whales headed back out towards the outer coast of Washington. K Pod wasn't spotted again until the evening of June 8 when they returned to the inland waters. At that time, researchers with the Center for Whale Research did confirm the new calf and gave it the alpha numeric designation of K-43!

It's believed the calf belongs to Sequim. She was estimated to have born in 1970 and was named after a Makah native village located on the Olympic Peninsula. At ~40 years of age, she would be nearing the end of her reproductive lifespan. If the calf is hers, this would be her 5th known offspring. Her daughter Raven died in 2006 (along with Raven's calf K-39) and her son Tatoosh died in 2005. Her two living offspring are daughter Sekiu (K-22) and son Rainshadow (K-37).
