When did killer whales become endangered species?
Answer:
The killer whale is not considered to be endangered. While some local populations are threatened, the Orca are still quite abundant in the oceans worldwide.
As a species, they are classified as "data deficient". This means there are different species of killer whales, and some of them may well be in need of protection. For example, in late 2005, the Southern Resident Killer Whales, which are a group of populations in the eastern North Pacific Ocean, were placed on the US Endangered species list.
