WL, "Any special tips for catching them?" Just don't handle them. It is my understanding that armadillos can carry Leprosy. For that reason, and safety in general, any live catch traps should have protection for your hand at the carrying handle. I suspect that the NWS5300 Universal Trap with built-in nose cone trap would be suitable for armadillos. However, several other traps, like the Wickencamp Coon Trap (Model 302) or the Safeguard Pro Raccoon Trap, are suitable for armadillos. For traps with a rollover release, you should anchor the trap to prevent the captured animal from rolling the trap over and escaping. I lost several large gray squirrels before learning to attach an anti-rollover bar (a short piece of concrete re-bar) to my Havahart traps. If you are trying to catch an armadillo, you might want to use TreeBerry paste bait. If you prefer not to use a live trap, you could try a repellent like Whole Control. I have never used it, so I can't attest to its effectiveness. If all else fails, you could always try "the old reliable" Juicy Fruit gum. (grin) MM

Those poweweful hind legs and a very big foot says rabbit to me. Also, the hind legs are outsized in length compared to the front legs, more so than for a canine. The carcass is in very bad shape. Imagine putting a pair of long ears on the head. Also, compare the size of the carcass with the oak leaf next to it. It is right sized for a rabbit.

It's a Sea Cucumber, an invertebrate that feeds on decaying organic matter. There are many different species. https://en.wikipedia.org/wiki/Sea_cucumber

I think the magic scientists who make the physiologies match could deal with the strings. As it is, most guitar strings are synthetic and/or metal. Harp strings are also made of nylon and/or metal. Piano strings are metal. Violin strings are also mostly synthetic and/or metal, though sheep's gut is still used sometimes for authentic historical sounds. The sticking point is the bow. Current synthetic bow filaments are too smooth and not as well liked as real horsehair, but that doesn't mean that they couldn't be made better. It's just not worthwhile to develop specially to imitate horsehair while horses are still being slaughtered in sufficient quantity to provide the real thing.
