HUNTING TACTICS OF ORCA KILLER WHALES
Who is orca (Orcinus orca)
Orcas or killer whales (Orcinus orca) are the alpha mammals of oceans. No one animal, fish or mammal in the sea can kill her. She is an incredible killer, her body is special. The killer whale is a special machine invented by mother nature to dominate the oceans. She can be ultra-rapid and at same time ultra-silent.
There are three different populations of orcas: The residents, the migrators and the offshore. And they have a different diet, consequently even different hunting technics.
Primary characteristic of the dolphin family
Another primary characteristic of the killer whales is the big clever. This characteristic is more evident in the group hunting. The strategy is absolutely amazing it seems like a military action.
One example of hunting tactics is the attack on the seals on the floating ice. According to the composition of the pod, the matriarch looking for a prey and when she sees it she calls the pod. The pod arrives close to the ice platform at very high speed and with coordinated movement provoke a wave that pushes the seal on the water where she will be captured and killed. You can think the seal is small and it is not enough for all components of the pod. Probably it is true but the orca’s pod will divide the food between all components in equal parts.
On the beach like a brave warrior
Another spectacular tactical action is the hunting of the sea lions on the beach. It is even a danger action but the killer whale is specialist and cleaver. One orca swims close to the beach where has been spotted a prey near the water. This orca will do nothing to hide, quite the contrary she shows very well her dorsal fin. The prey looking for the menace is concentrated to control her movements and is in this moment that the second killer whale fast arrive. She has been hidden all time and now is a second is out of the water to take the seal or most times a calf of a sea lion.
The return into the sea is not simple for orcas but her powerful musculature help.
No natural enemies for killer whales
Killer whale (Orcinus orca) the king of the sea, just the man are a danger for her. She dominates the large part of the earth because the two-thirds of the earth is covered by water. She is very adaptable and thanks to her cleverness in any situation she can take advantage.
Her hunting tactics is efficient even against white sharks and other sharks species. But maybe the most impressive is technically employed in the hunting of whale calf. The pod works together to separate the calf from the mother. When the calf is separate an orca will cover with her body his dorsal blowhole up the whale dies.
Orcas and man
Despite this incredible power demonstration, an attack against a man is never been recorded. The only attacks documented are the occurred in captivity. According to the scientists that attacks against humans have been caused by the stress of the captivity. Above all, we want to remember the dramatic story of Tilikum and her trainer.
To demonstrate the sweet character of killer whale (Orcinus orca) there are many amatorial clips recorded by people on small boats like these orcas in the New Zeland coast.
