[86] The pair of orcas repetitively called in "long 'conversations' while floating side by side" without engaging in any behaviors requiring the exchange of any information.
The Salish Sea orcas have become an iconic natural treasure of the region and a symbol of the area's ecological productivity. Many whale watching organizations throughout the region target the orcas, including resident and transient groups, and often work with nonprofit organizations like the Center for Whale Research and The Whale Museum to ...

The small, furry sea otter offers little nutrition for an orca; however, orcas are so large that a handful of ...
The genus Orcinus was published by Leopold Fitzinger in 1860, [4] its type species is the orca named by Linnaeus in 1758 as Delphinus orca.Taxonomic arrangements of delphinids published by workers before and after Fitzinger, such as John Edward Gray as Orca in 1846 and Orca (Gladiator) in 1870, are recognized as synonyms of Orcinus.
