Guess the bug?

This is on my deck...what the heck is it? Sorry for the bad pics. It looks like a bright lemon yellow bloated tick, but I know that isn't what it is. Any ideas?

i would say itd be a dead bug well it would be if i was there

My guess is a yellow crab spider who has been through war and lost some of his legs. The poor thing! They usually have their 2 front legs much bigger than all the others which they use to grab prey. They seem to be missing in this picture.

They don't weave webs to catch prey - they ambush!

Thanks, that is what it is. I had no idea what to google because of the lack of legs. It's pretty neat looking, I've not seen one before.

I saw a bright green one just like it at work the other day. Strangely enough, it was also missing one of it's front legs.
