Scientists discover 10 new species of sealife at bottom of Atlantic Ocean

Oddly-shaped, brightly-coloured or even transparent these are some of the bizarre creatures that scientists did not even know existed until recently.

They are among a host of new animals that scientists have just uncovered in the hidden depths of the Atlantic Ocean during a new study which has 'revolutionised' thinking about deep-sea life.

Scientists believe they have discovered more than 10 new marine species by using the latest diving technology during the groundbreaking study.

The voyage was carried out as part of the Census of Marine Life programme and was the last in a series of four annual voyages undertaken since 2007.

Ben Wigham of Newcastle University, which is also taking part in the project, said: 'We are interested in how these animals are feeding in areas of the deep-sea where food is often scarce.

'The differences we see in the diversity of species and numbers of individuals may well be related to how they are able to process and share out a rather common but meagre food supply.

'We certainly see indications that there are differences between the north and south regions of the ridge.'
