Killer Whale Orcinus Orca
The king of the food chain, the master of the sea. 
You don't quite realize how unreal this dolphin is until you see it in the wild for yourself. Yesterday i went to Kaikoura Whale Watch (Whale Watch) and saw 4 of these crazy beasts. They were pitch black, very very fast and just 100% extraordinary.

A toothed whale belonging to the dolphin family, found in every ocean of the world and held captive in many marine entertainment parks where they're known to be treated with ill respect and not given all experiences or recourses wild Orca would have.
This species has been named endangered or threatened because due to less food source, pollution, capture for marine mammal parks, habitat loss and conflict with fisheries.
The name "Orca" comes from the name of this dolphin's family, "Orcinus" meaning "of the kingdom of the dead" and is used commonly instead of their other name "Killer Whale".

Females mature at around 15 and mate until around the age of 40, when they (the only other animal like us) go through menopause and live for 10-40 years longer without reproducing. The females have one calf around every 5 years and 37-50% of these die during infancy. Apparently every member of the pod takes part in raising the calves. Males and females sexually mature at 15, but males generally don't reproduce until the age of 21 and only live for 29-60 years.
Females live with their mother for their whole life and this group can hold up to 4 generations because of the large life span Orcas have.
To communicate, Orca use clicks, whistles and pulsed calls. These are partially unique to the pod, like we have unique languages for every country.
Their brains are second heaviest after the Sperm whale, and they are often classed as very intelligent. Some examples of their intelligence are; their technique of deliberately beaching themselves to catch seals, or catching seals then releasing them alive near a group of young to give the young hunting experience, and stealing fish from fishermen's nets. There were a group of fishing boats which tried to avoid this by placing many boats in a line and each catching just a small amount of fish, thinking the Killer Whales wouldn't be able to steal all their catch. But, they soon figured it out and when they figured that the fishermen were playing a game with them they began breaching (flipping out of the water playfully) by the boats.
This movie is about the famous Killer Whale Keiko, also known as Willie, the star of the hit movie Free Willie. It's worth a watch.(Free Willie Doco)
