Are orcas and killer whales the same animal?

No no no. BIG difference!Orcas are also known as Killer Whales or you might know them as Shamoo for those Sea World goers. Orca's are a type of tooth whale and are known for there black and white coloring. They travel in pods and attack other whales, usually separating the mother from its calf and eating the baby. Whale sharks are HUGE sharks bigger than Orcas but smaller (By a LOT) than Blue Whales, which Fun fact , There heart is the size of a Volkswagen Bug!
