This post reminded me of an encounter I had where a small eastern hognose was being swallowed by a speckled king several times its size. I would have never known they were there if the (hog?) hadn't been making a high pitch humming noise. The king had half of him swallowed(I guess the hognose was too small to constrict).Anyway I pulled the hog out of the kingsnake's mouth and let it go. I kept the kingsnake. I listened to that noise for a few minutes before I finally found what was making it.The kingsnake shouldn't have had any trouble swallowing the hognose of that size in seconds.
