A rare "shark nursery" discovered in deep waters west of Ireland



A huge shark "nursery" roaming from predatory fish and strewn with eggs was found in the waters 200 miles from the west coast of Ireland.

This rare discovery was made by a remote-controlled vehicle researching coral reefs of cold water at a depth of about 750 meters.

Researchers have observed a large school of blackhead, a relatively small species found in the North-East Atlantic, along with a more unusual and lonely sail rough.

Boxes with eggs in the field or siren purses rarely meet in such a large number and are believed to belong to cats.

While there were no shark puppies in the area, the scientists in the SeaRover survey, which captured the material, want to keep an eye on events and potentially observe how they hatch in the future.

"No puppy was obvious at this point, and it's thought that adult sharks can use a degraded coral reef and an exposed carbonate rock on which to lay eggs," said David O & # 39; Sullivan, principal scientist at SeaRover.

"A healthy coral reef nearby can provide shelter for juvenile young sharks after hatching.

'Further terrain research is expected to answer important scientific questions about the biology and ecology of deep-sea sharks in Irish waters.'

The new findings were announced during the INFOMAR seminar on seabed mapping in Kinsale this week, during which marine science scientists played the main events of the Holland 1 submarine vehicle.

"We are pleased that this discovery was presented at today's event, showing how important it is to map our habitats to the seabed in understanding and managing our huge and valuable oceanic resources," said O & # 39; Sullivan.

"Our data and team are still making a significant contribution to the use of our ocean wealth."

Informar is an Irish government initiative, and the new discovery will help the country meet its obligations to monitor deep sea sharks under the marine environment protection program.

The nursery was found in one of six special protection areas in the vast Irish territory.

These regions, designated by the EU, are home to a huge variety of creatures from sea fans to different species of fish. Due to the protected status, fishing trawlers can not operate in these zones.

"Our main goal is to assess, protect and monitor the rich ecological marine biological diversity of Ireland so that we can effectively manage our marine resources," said Dr Yvonne Leahy from the Irish National Parks and Wildlife Service.

"Without knowing what lives in our seas, we risk that we will never fully understand and underestimate the marine environment of Ireland."
