April 2013 K25 and pod mate "K pod of the critically endangered Southern Resident Killer Whales swam slowly north through Colvos Passage (the west side of Vashon Island) in a resting pattern on 12/29/12, accompanied by a research boat from NOAA." Photo c/o Western Prince Whale & Wildlife Tours website Found in all the world’s oceans, killer whales (Orcinus orca) are the largest member of the family Delphinae. Despite being found worldwide, killer whales are at risk in several areas. Currently at debate is whether there are subspecies of killer whales in certain ecosystems, and if so, whether some of those populations are endangered. Of particular concern are the so-called Southern Resident Killer Whales of the Salish Sea. Within the Salish Sea area are three potential subspecies of Killer Whale. Residents, such as the Southern Residents, are fish eaters and have curved dorsal fins. Transients hunt other marine mammals (such as seals and porpoises), and have more triangular dorsal fins. Offshores primarily live off the continental shelf in the Pacific Ocean. While their summer range of the San Juan Island area is well documented, the Southern Residents' winter range has only been speculated. Photo c/o Orca Network How You Can Help It starts at home. Recycle, dispose of trash responsibly, compost if you can, pick up after your dog.
Help with stream clean up efforts. Contact your city or local environmental stewards to find opportunities.
If you go whale watching, choose only responsible companies that adhere to the strict laws. Remember, vessels must stay 200 yards away from whales!
Visit The Whale Museum in Friday Harbor, WA to learn more, and support local research.
Make informed decisions when planning your vacation destination. Do you feel good about supporting an institution that houses large marine mammals?
Report sightings of Killer Whales and other marine mammals by contacting The Whale Museum, or Orca Network. K25 Photo ID c/o Center for Whale Research More Info: Center for Whale Research www.whaleresearch.org
