I've corrected your last attempt at giving a link. I'm not sure what you are doing wrong but please read carefully the posts about images in "Guidance - How to" section.

Your images are a bit small, and even when I zoom in, I am not sure about the plant. It could be M. schumannii, as the body looks grey-green, but the hooked spines look longer than I have seen, but this may not be important.

Thanks a lot. When I get a large picture, I will upload here to let you identify again.
