Marine biologist Brian Hellmuth of Northwestern University also told CNN that when mussel banks die like corals, this is a marine health warning that can have significant ripple effects.

When we see mussel banks dying, they are like trees in a forest that provide a home for other species. So it’s very clear that the oyster shell is dying, he says.
