An orca (Orcinus orca) known as J-1 surfaces in the southern end of the Strait of Georgia in British Columbia, Canada. This whale was nicknamed Ruffles because of the wavy appearance of its 6-foot-tall (2 meters) dorsal fin. Ruffles is a member of the J pod of orcas, also known as killer whales. The J pod is one of three groups of orcas that regularly reside in the waters around Washington's San Juan Islands. Scientists believe Ruffles was born in 1951, making him the oldest male in the pod.
