Ship noise increases shore crabs’ metabolism, a new study suggests. The researchers found that larger crabs were particularly affected by recordings of ship noise in controlled experiments. Increased metabolism is a sign of stress and could potentially reduce the growth of crabs and have implications for their survival, as well as for fisheries.

Ocean pollution 'threatening biodiversity more than is currently recognised', warn researchers

Researchers have discovered that the problem of ocean noise pollution extends all the way up to the shoreline. And shore crabs face a double-edged sword from too much noise from ships.

New research finds that on just two remote islands alone, nearly 600,000 crabs are killed every year by plastic debris.
