The Captivating Grey Seal: A Fascinating Marine Mammal
The grey seal (Halichoerus grypus) is the second largest seal in the world, second only to the elephant seal. It lives in the northern Atlantic, with half of the world's population living around the British Isles.

For hundreds of years the seals were absent or in very low numbers in the North Sea, mainly due hunting. Since the 70s though, when protection for the seals started to be put in place, they have flourished.
Grey seals spend more than 80% of their time at sea and 90% of that below the surface. They are curious and will approach divers, especially the younger seals.

The seals return to the same shore to haul out. They don't stay close to that area though, they can travel over 100 km between their haul-out and foraging sites. These feeding trips last as much as 30 days, and they can cover the 100 km in just one day.

Like most marine mammals, grey seals communicate using calls and whistles, but these seals also clap to warn off competitors and advertise to potential mates.
Amazingly, grey seals can dive to 477 metres. However, they mostly don't go much below 100 m, searching for food.

Female grey seals have been recorded living to 42 years in the wild. Males are thought to live less long, to a maximum of 31 years.
The grey seal is so called because of its coat, which is various shades of grey. The pups though are born white. Female pregancies last 11 months, and they then look after the pup until around three weeks later when it is weaned.
Harnessing the sun to make Red Sea liveaboards more sustainable Liveaboards are one of the best ways for divers to experience the Red Sea. Their diesel generators though contribute to climate change and air pollution. That's why one liveaboard operator is to use solar panels.
Titanic: First ever full-sized scans reveal wreck as never seen before The first full-sized digital scan of the Titanic, which lies 3,800m (12,500ft) down in the Atlantic, has been created using deep-sea mapping. It provides a unique 3D view of the entire ship, enabling it to be seen as if the water has been drained away.
Why The Ocean Cleanup might not be a good thing The Ocean Cleanup's aim is to remove plastic from the ocean surface by collecting it with large nets. However, this approach also kills the surface marine life, like the beautiful Blue Sea Button Jellyfish.
