Shell Shocked

The fall in number of shellfish in oceans has been linked to the rise in noise from man-made activities. Activities like underwater drilling cause large-scale physical malformations in marine invertebrates, such as shellfish. In an experiment on the New Zealand scallop larvae, it was found that the scallops which were exposed to noise went through a delay in development, with 46 per cent having malformations. How does noise impact these microscopic larvae is unclear and requires further research.
