#OrcaFacts: Orcas, like all dolphins, swallow their food whole. Their sharp teeth are used for ripping and tearing but are not suited for chewing.

#OrcaFacts: Southern Resident Killer Whales are some of the only animals we know of to concretely display social learning. Many of their behaviours are passed down from mother to calf through generations.

#OrcaFacts: Norway’s orcas are most often associated with the mass migration of herring which arrive in their Northern fjords every winter. Many Norwegian orcas hunt their herring prey using a technique called “carousel feeding” where multiple members of a pod encircle the herring,

#OrcaFacts: There are many distinct populations of Orca around the world. So far scientists recognize 5 different ecotypes in the Northern hemisphere & 5 in the Southern although new evidence for speciation has been proposed.

#OrcaFacts: Of the three Killer Whale ecotypes you can find in British Columbia, Offshores are the most mysterious and the least studied despite the fact that they seem to travel in extremely large groups, sometimes of over 50 or 100 individuals!

#OrcaFacts: Killer Whale mothers are in it for the long haul. They are pregnant for an incredible 15-18 months, will nurse their calves for ~2 years & in many cases it’s believed that their young swim the rest of their lives by their side.

#OrcaFacts: There are three different kinds of Killer Whales off the coast of BC: The fish-eating Residents, the marine mammal eating Bigg’s or Transients and the elusive and rare Offshores, who are confirmed shark eaters.

#OrcaFacts: Scientists studying BC’s Offshore KWs noticed that their teeth were very worn down which led to them to hypothesize that they were feeding on rough skinned sharks This was later confirmed to be their primary source of food.

#OrcaFacts: New Zealand is home to between 150-200 killer whales who can be seen most frequently from December and March. They forage on numerous species but some specialize in catching stingrays right in Wellington harbour.

#OrcaFacts: Though many populations of Killer Whales travel through Scottish waters, there is a small unique individuals who call the Small Isles and Skye home. This pod, fondly referred to at the West Coast Community, have been seen preying on porpoises, dolphins, whales, and seals.

#OrcaFacts: Bigg's hunt marine mammals-everything from small seals to whales twice their size! They are also frequently found in much smaller groups than Residents and their family bonds do not appear to be quite as strong.

#OrcaFacts: Type D Orcas are a subantarctic ecotype, first discovered in the 1950s. They share the same black-and-white colouring on their dorsal and ventral sides as other orcas but they have shorter dorsal fins, rounder melons, and the smallest eye patch of any ecotype.
