I picked out a coyote claw (left) that was very close to the same size as the raccoon (right). This was based off the end on the phalanges, they were VERY close in size.

One thing I noticed right away was the dramatic change in thickness from the tip of the raccoon about 1/4 the way down it gets much thicker without much tapering, as the coyote gradually gets thicker towards the base. I remember seeing the same type of nails when I had my iguana, which was another arboreal creature, I can only assume that shape is common for tree dwelling creatures. It makes sense too, the thicker part gives strength while the thinner part dig into and around bark.

The Raccoon is also obviously VERY much more curved than the 'yote.

I'm going to keep at least one canine and craw from all the animals I work with from now on so I can develop a wide array of comparison and reference materials.
