As the Oceans take up man made carbon dioxide from the atmosphere, their chemistry is changing faster than ever before; a phenomenon known as "Ocean acidification".

Here we show that Ocean acidification has a positive effect on calcification and metabolic activity in the brittlestar Amphiura filiformis; contrary to previous thinking.

However, this positive effect comes at a biological cost, seen as muscle wastage.

Our study demonstrates that whilst organisms may be able to respond to Ocean acidification in a previously unexpected way, the energy trade-offs associated with this response present a considerable threat to the future survival of calcifying species.
