The world "needs" orcas in the same way that the world "needs" humans: not really at all, but they're awfully nice to have around.
To save the orcas (killer whales) you need to stop polluting in rivers, lakes, oceans, etc and spread the word to the world before its too late!
Orcas enemies are man, because they are feared by almost every animal in the world.
the blue whale is the largest.
Orcas are not whales. They are the only marine mammals that would eat another whale. Orcas are the fastest of marine mammals. Shamu (at sea world oralado) is the most famous marine mammal! ( He is an orca )
Killer whales, otherwise known as Orcas.
Shamu is a stage name. The orcas have their own names. There are currently 40 orcas in captivity.
they dominate every ocean and will eat anything that comes into there territory. although some people portray orcas as cold blooded killers they are really smart and they have a need to bond with their parents or people by mistake. /orcas can eat great white sharks
orcas reproduce when they are ready.
Orcas are not endangered!!! Orcas have a high population, so that that no one know how many!!!
155 orcas have died in captivity. Curious answer, especially considering the fact that Sea World has only bred 20 whales and that only about 7 of the total whales(captures included) have died. Curious, no?
Orcas have no particular breeding season.
Orcas eat liver as part of their diet because it is a rich source of nutrients and vitamins that help them stay healthy and strong. Liver contains high levels of vitamin A, iron, and other essential nutrients that orcas need to thrive in their marine environment.
