Though I have read sources stating that alligators and crocodiles generally have a comparable bite power at similar sizes I always have gotten the impression that crocodiles seemed to have a far more lethal bite.
For example these crocodiles seemed to have a much easier time destroying terrapins with larger tougher shells than these alligators.
vs
Is it possible that the crocodiles generally longer teeth enable it to inflict more damage when it bite down on something? Or is my selection of videos simply not broad enough and is biased?

Though I have read sources stating that alligators and crocodiles generally have a comparable bite power at similar sizes Could you list one of these sources? I think the easiest method to determine who is stronger is to scale both at the same size. I don't know how to scale bite force, but I once saw that scaling method (carnivora mamber brolyeuphyfusion used it, I know, he is not so reliable, but it is the only method I know): ( ( length of animal a /length of animal b ) 2 ) * bite force of animal b = bite force of animal a About your videos, I think it depends on how much efford these guys put in their bite, some may be less motivated. |

If I'm not right, this question has been discussed in some paper talking about crocs and alligators bite mechanisms.
Oh yeah, I would never use anything from broly as reliable, even if he's right, this guy is such a piece of bias that he destroys even the reliability of his good material.

Body mass is better determinant and forces scales isometrically seen with an exponent of (2/3) in this case, head width also works well. However there are far better empirical formulas for crocodylian bite force published in several Erickson studies. The latest www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0031781 |

It seems the exact morphology that makes it stronger also makes it less efficient, that's basically like slicing vs crushing. But gators don't have stronger bite forces than crocodiles, do they?

Maybe someone could scale the bite force of an alligator to the bite force of a hypothetical saltwater crocodile-sized alligator, so that we can compare them.

I would suggest you read the paper I posted. There was little connection between skull shape and bite force, and mass was the best predictor for force regardless of morphology. |

That explains it. Of course, the same force distributed over a greater area (blunter teeth and broader jaws on gators) will not do as much damagebe as effective. So crocodile snouts are weaker, but more efficient (similar to BI's info on hyaena vs wolf)

Impressive display of a crocodile's power.
Its interesting to note that the crocodile's jaws seems to be able to exert a significant amount of pressure, even when only the front portion of its jaws managed to latch on to its target.
