Anenomes eating Urchins

[MichaelMc]

Are urchins a good meal for anemones? I saw an anemone engulfing an urchin and wondered if it would digest its internals. Or if the effort would be worth the reward. How long do they take to digest a meal?

we just need the sea otters to stop being so lazy and do their job of urchin removal
