The main difference is the animals hunting because any environment have his different fauna and different is even the technique used. Generally we can say the orcas hunt with strategy group, many elements they join in the hunt and constrict the prey to be isolated and so they kill the prey. We are on front to different groups of orcas but are not considered subspecies, according with the scientists this groups are considered and called ecotypes . Another difference is the communication, any ecotype has developed different sounds like to underlined the difference from other ecotypes. Someone think this is happened in the species evolution, with no interaction they don’t compete for the same food, this process is started millions years ago.

Major risk: Major risk depend from the location, but the pollution is a big risk, the boats noise even is a big issue, orcas use the sounds like a sonar for to recognize the prey but the increasing of background noise disturb the localization.
Even this beautiful animal is not lucky, it was hunted a lot for to show in sea parks and aquarium, do you remember? We told about this problem in the post Killer Whale and Water Parks, I invite you to read that post because is necessary to understand what is behind the sea parks business and the future of the Killer Whale.
