Unfortunately we do not get that show.
As to the bigfoot terminolgy, it was the fifties when Bigfoot was the name penned to all of the known creatures names/types. Similarity in its description suggests that it was a big hairy man/ape with big feet and thus is easier and most likely to be refered to as a BF. Americans tend to call the Sasquatch/Yeti/Skunk Ape/Snow Man a Bigfoot.
Should proof of any of the creatures be found, especially a variety of the creatures for scientific study, then maybe a more broad and defined defenition may be applied, and people such as our selves can categorize the different kinds of this fantastic legend that has been seen all around the world.
Since there are some different types of tracks, I would think that there are many species-thus your arguement has an interesting point.
A post on the descriptions, print conclusions,size,coat, etc. of these creatures might help us all to understand the proper terminology to use in such reports.
Do you have any info to define the differences of these creatures? If so, please share. This is a good subject that may help researchers in this field.
