my sea urchin murdered my crab
 
i came home to find my little crab at 50 percent biomass in my sea urchins mouth. i believe it was predatory (unconciously) the crab was healthy 2 hours earlier. wtf?

Without identifying what species were involved iy would be difficult to assume what happened. Most urchins eat algaes. Wondering if your crab died and the urchin came up on it. Are you sure the crab did not molt? From the urchins I've kept, I could not fathom how a healthy crab could even be caught by a typical hobby urchin.
