Most scientists believe that the early Earth was buffeted by a series of asteroid impacts, each of which wiped out many species, at least one coming close to wiping out all life itself. I was surprised to learn that the marine life suffered much greater losses than life on land. I would have thought that life in the seas would have had some protection from the blast of such impacts, and the subsequent atmospheric effects, including the drop in temperature, but it seems not to be the case. Any idea why not?

In general, the marine life has a more delicate balance than terrestrial life. For starters plants are far more adaptable than animals, but in addition to that, things affecting the ocean temperature, salinity, etc, in essence affect the entire climate and are inescapable changes.
I can't think of any terrestrial change that would affect the way animals breathe the air so completely and absolutely the way oceanic changes do.

there is extra air than water, so a metamorphosis in water could have extra relative effect. interior the air, there is extra "wiggle room" for alterations to unfolded extra gently. eg, a tablespoon of water will warmth up plenty speedier than 2 tablespoons of air.
