The history of killer whales is a very important one, because if we do not learn about these amazing creatures now, we may face a future without them. The Killer whale population has been incredibly stable for the last 100 years, but over the past ten to fifteen years, there have been several increases and decreases in the populations. Because of this, it has been difficult to determine why the numbers have decreased.
There are a number of theories as to why the decreases have occurred, and some of the theories are based on nature, and some on human interaction. For example, if a male whale becomes stressed out, or if a pod of whales were threatened by someone, then they may become less active. There have also been theories that suggest that the Killer whale populations are directly affected by shipping congested areas, and by the addition of people to the wild population. When more people are mixed into a wild population of killer whales, the numbers decrease.
It is believed that the decreases in the Killer whale populations are due to captivity, and to the efforts of humans trying to help these animals. In most cases, when killer whales are put into captivity, the males are sold to pet shops for a price that is less than half of their reproductive value. Males are usually only bred a few times, before being killed, and when this happens, the females that remain in the wild are attacked by other males for reproductive purposes. There have also been reports that when wild female killer whales are put into captivity, they will allow one mate with another, and a new generation of babies will be born.
If you are interested in learning more about the history of killer whales, then you might want to read a book by Dr. Thomas H. Reibert called, “The Killer Whale: A Complete Overview”. This book covers the history of the killer whales from their arrival in captivity, to their decline in numbers. It also gives an account of how the American government tried to save the species in the past, and the steps they took to acquire it back. If you like factual stories, this is a good book for you.
The last section of Reibert’s book covers the hunting of killer whales in British Columbia in the 1990s. The reason why this happened was because hunters were targeting the younger, weaker male calves. The result was that a lot of the whales became extinct, including at least one subspecies. The other subspecies, called the Galapagos killer whales, survived thanks to modern fishing practices. The book also goes into why the area needed to be protected in the first place.
Reibert’s book has a very thorough look into the history of killer whales, and why they are disappearing. We also get a look into how the marine ecosystem is functioning, and what can be done to preserve it. This book would make a great textbook for students in college, because it so accurately and beautifully details the habitat and the environment. I highly recommend reading it. The price is reasonable, and you will learn a lot from reading this fascinating tome.
