Orcas demonstrate that they are the ocean's top predator for good reason

The Galapagos Islands are home to some of the most diverse and fascinating creatures on the planet. A relatively new world, the islands were born from volcanic eruptions that sent towers of rock from the ocean bottom, upwards to the surface. Over time, birds and insects found the islands and made their homes here. Currents from the ocean converge in this area and bring an abundance of sea life. With the ample food supply came larger marine animals such as whale sharks, Galapagos sharks, hammerheads, sea lions, sea turtles and fish of great variety.
Orcas, known as killer whales, also come to the Galapagos Islands. They are the ocean's top predator, and for good reason. Their enormous size and power make them formidable enough, but they are also extremely intelligent and they hunt cooperatively. With sophisticated communication and impressive logic and reasoning skills, they can take down almost any animal they wish. These orcas leave us with no doubt that they are unequalled in the aquatic world.
This video shows a pod of killer whales that have killed a fully grown hammerhead shark. They take turns tearing the shark into pieces and eating it. A very fortunate scuba diver was able to capture the footage as he returned to his boat, preparing to leave the water. Despite the fact that these orcas are fully capable of harming humans, there are almost no recorded attacks on people.
The hammerhead shark is considered an apex predator in many waters, but when the orcas arrive, there is no doubt about who is the boss and top of the food chain. Even great white sharks will leave an area when it become inhabited by orcas.
