These combined images show, at left, a healthy pteropod collected by NOAA and Oregon State University scientists, and at right, one that shows signs of damage from ocean acidification. The white lines on the grooves of the shell at right show areas where it is beginning to dissolve. The pock marks and white spots are signs of severe dissolution. Provided by NOAA
