Are marine organisms evolving to protect their young in response to ocean acidification?

Marine organisms living in acidified waters exhibit a tendency to nurture their offspring to a greater extent than those in more regular conditions.
Scientists have found that polychaete worms located around volcanic vents in the Mediterranean grow and develop their eggs within the protection of the family unit -- in contrast to closely-related species that release them into the water column to fend for themselves.

1. is the water around volcanic vents high in acid content?

if so, then they will live.

shell fish are already showing pitting and soft shells due to acidification.
