Long spined urchins have venum in the spines.

The urchin sure looked like it did exactly what you are talking about with
the sea stars. I don't think I saw the stomach come out, but maybe it did.
But this was no mechanical ripping. There was no question that 3/4 of the
anemone, the part touched by the urchin, was chemically destroyed and already
rotting, within an hour. The color went from the usual translucent pink, to
solid white. Just horrible.
