Wild Animals/Killer Whales


Hi, I really need help, hope you can give me that.
I have a project in school about the Killer Whale population. The omly thing is that i need to know the number of the antarctic population in 1900, 1960 and 2012. I can't seem to find it anywhere.
Please help me!

Dear Julie

Thank you for your questions. I also wish to thank the authors of the websites I used. You may find http://www.nmfs.noaa.gov/pr/species/mammals/cetaceans/killerwhale.htm and http://www.seaworld.org/animal-info/info-books/killer-whale/habitat-&-distributi useful.
http://www.nwr.noaa.gov/Salmon-Hydropower/Columbia-Snake-Basin/upload/Final_SCA_ gives a graph showing population trends for southern resident populations from 1960-2006.

One of the problems in counting populations is that there are three different types of killer whales: transient, resident and offshore and there are indications that these may represent more than one species (http://en.wikipedia.org/wiki/Killer_whale).

http://www.coolantarctica.com/Antarctica%20fact%20file/wildlife/whales/orcas.htm suggests that the current Antarctic population is about 70,000.
I would be very surprised if there are accurate records from 1900 and I could only find figures for resident populations in 1960 (http://www.nwr.noaa.gov/Salmon-Hydropower/Columbia-Snake-Basin/upload/Final_SCA_), although you may be able to make an educated guess on the total population comparing these figures with the figures for the total population in other years.

I'm sorry I couldn't help year, but I suspect we both checked the same websites. It may be worthwhile contacting the British Antarctic Survey and checking if they keep figures. Details are at http://www.antarctica.ac.uk/about_bas/contact/index.php.

All the best

I can answer questions about wild mammals and other animals, as well as extinct animals and zoos. I am not an expert about every animal species. I can look up information from books and the internet, but can't verify if all the information is true. Please don't ask questions about: 1. Pets. I am not a vet. Please contact a vet if your pet is ill. You may need to spend some money if you want your pet to live. Don't get a pet if you don't know how to look after it and if you can't provide it with the space, food and possible companions that will help it live a healthy life. Don't take animals from the wild, unless they are ill and/or injured and you can protect them until a wildlife charity can help. It is cruel to take animals from their parents, especially if the parents will look for the babies, while putting their other babies at risk. You may be breaking the law by keeping wild animals or you may need a licence to look after some species. Please check with a local wildlife group. 2. Eggs: Please don't remove eggs from nests. The mother birds provide the right temperature for the eggs and won't sit on them if the temperature is warm enough for them to develop naturally. It is illegal to remove eggs of some species and, unless you have an incubator or a broody hen, the egg may not develop. If you are allowed to touch the eggs, you can candle them to see if they are fertile. If theys aren't fertile, they won't hatch. 3. Fights: Please don't ask about fights between different animals. These questions assume that individuals of two species fight each time they meet and that one species will always be victorious over another. This is untrue. There are cases where a live mouse has been fed to a venomous snake, bitten the snake leading to the snake's demise. 4: Diseases: Please ask doctors or other medical experts about diseases that you may catch from animals. I can't advise on how to deal with viruses, bacteria etc.
