Well, not exactly dig their own graves in the sense that they kill themselves doing what comes naturally. They usually die a natural death. And then they literally fall apart, to get washed out and distributed in fine layer of spines and test plates. More like the scattering of ashes, than a grave.

If you ever dive into blogging more regularly, I think you could give Chris Mah a run for his money (and that’s saying something).

I’ve heard that sea urchins can literally dig their own graves, as they grow larger and get stuck in their holes. True?
