Bite Force

- How strong is a wolf's bite in pounds per square inch?
- How do they compare to other animals?
- Do different species of wolves have greater differences in bite force?

It might vary, but considering there are only a few recognized species of the wolf, I don't think it varies greatly between the actual wolf species. Do you mean subspecies?

- How strong is a wolf's bite in pounds per square inch?

1,500 psi

- How do they compare to other animals?

Greater than that of any other existing canid, but lesser than that of bears and hyaenids. Way below that of crocodilians.

- Do different species of wolves have greater differences in bite force?

Don't you mean subspecies? If so, the bigger the grey wolf, the bigger the bite force. It's that simple.

• I dug up a paper that generated bite force quotient and canine (the tooth) bite force data from skulls for living and extinct mammalian carnivores: http://www.jstor.org.subzero.lib.uoguel ... e/30047894. I hope access isn't restricted to university students... go look at table 1.
  
  While I cannot confirm nor deny the Of Wolves and Men 1500 psi value (couldn't successfully convert from psi to Newtons without getting wacky numbers), it is interesting to note that gray wolves have a greater canine bite force than hyenas. But that is just considering one tooth type. This highlights the importance of keep in mind what type of bite force data you are looking at!
