Cuttlefish tags: Tracking the 'kings of camouflage'


Researchers have been attaching tags to animals as diverse as whales and ants - but now it is the turn of the cuttlefish.

These enigmatic sea creatures, with their colour-changing skin, can be found throughout the English Channel - but they are extremely difficult to study in the wild.

They come inshore in spring and summer, but little is known about their migration in the autumn.

Now scientists are fitting 100 cuttlefish with tags in a bid to find out more about where these "kings of camouflage" go and also to shed light on their behaviour.

The data from the tracking devices will also help researchers to assess the impact that the fishing industry is having on them.

Increasing numbers of cuttlefish are being exported to France, Spain and Italy for food, but the scientists want to see if this is sustainable.

Here, Dr Victoria Wearmouth, from the Marine Biological Association in Plymouth, takes to the seas to explain how the tagging project works.
