What is the average weight of a Barbary lion.
Which has a higher bite force a lion or gorilla.

Dear Gautam Mayya

Thank you for your questions. I also wish to thank the authors of the websites I used.

1-3: Please note that I no longer answer animal fight questions. It assumes that all animal fights between 2 species will have the same outcome. There have been cas where live mice have been fed to venomous snakes. The mice have bitten the snakes and the snakes have died. Similarly, other animal fights are not necessarily as predictable as they would appear to be, nor will many animals deliberately pick a fight with another species, especially as there is a risk of injury and possible death for no detectable benefit. Please contact the Interspecies Conflict section at http://www.allexperts.com/el/Interspecies-Conflict/.

4: http://www.speedofanimals.com/animals/lion says a lioness can reach 81 km per hour over short distances. https://uk.answers.yahoo.com/question/index?qid=20110326161044AAB42R8 seems to suggest that the lioness is slightly faster than the male, but there is very little to choose between them. http://scienceline.ucsb.edu/getkey.php?key=1041 says that the lioness is a stronger runner than the male. Both these statements make sense, as lionesses do a lot of hunting for the pride and use speed to help bring down prey. The lion tends to fight for the pride and protect it, where physical strength is more important than speed.

5: http://www.tigerhomes.org/animal/barbary-lion.cfm gives an average weight of 325-425 pounds for a female and 425-500 pounds for a male. http://animalsversesanimals.yuku.com/topic/2596/The-700-pound-Barbary-lion-club says an average wild male weighed 189-194 kg, while a captive weighed 650-700 pounds, while https://www.facebook.com/notes/morocco/conservation-of-moroccos-barbary-lions/10151245856274766 gives the average weight of a male as 550 pounds.
http://www.wisegeek.com/what-is-a-barbary-lion.htm#didyouknowout gives a figure of about 550 pounds (249.5 kg) for males and about 350 pounds (158.8 kg)for females. This seems about as close a figure to the average as I could find.

6: http://listverse.com/2012/11/05/top-10-animal-bites-that-will-completely-destroy gives the bite force of a lion as 600 psi (pounds per square inch), while the gorilla has 1,300 psi. http://www.buzzle.com/articles/animals-with-the-most-powerful-bite-force.html gives 650 psi for the lion and 1,300 psi for the gorilla. The other websites I visited state that the gorilla has a higher bite force than a lion.

You may find http://intern.forskning.no/dokumenter/wroe.pdf useful as it compares different ways of measuring bite force.    

I hope this helps.

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.
