Something tells me not to eat stuff which is still alive like grasshoppers, yet they often provide a completely viable, relatively risk-free source of nutrition.
Like I'd have a problem eating this sucker if it was still alive :
.. even if you cut off the pincers .. Yet I don't think it would be considered dangerous to do so. I'm not sure it's not completely unfounded (are any fears?), but I don't think it's completely rational.
