LiveScience: Sharks exposed to ocean water acidified by too much carbon dioxide alter their behavior, swimming in longer spurts than sharks in typical ocean water, particularly during their nighttime wanderings.
The new findings, published in the journal Biology Letters, are troubling, given that one effect of the human consumption of fossil fuels is to make ocean water more acidic. If fossil fuel burning continues as is, sharks may face even more challenges than they do today -- when a quarter of species...
