Three orcas that have not been previously documented in Seattle-area waters have made multiple visits to the region, according to marine wildlife observers.

The killer whales, which had no prior recorded presence in the Seattle area, have been spotted on several occasions by whale watchers in the region. The appearances have generated interest among both researchers and the public who track marine mammal activity in Puget Sound.

The identity and origin of these three orcas remain unclear, as they do not match existing catalogs of known whale populations that frequent Pacific Northwest waters. Marine biologists typically maintain detailed records of individual orcas through photo identification of their distinctive dorsal fins and markings.

The repeated sightings suggest the orcas may be spending extended time in the area rather than simply passing through during migration. Their presence has provided opportunities for whale watchers and researchers to observe and potentially document these previously unknown individuals.

Puget Sound and the waters around Seattle are home to several resident orca populations, making the appearance of unrecorded individuals particularly notable for marine mammal researchers who study the region's killer whale populations.
