There was a discovery of the rare shark nurseries located 200 miles west of Ireland. This is called a discovery on a "scale not previously documented in Irish waters."
The film recorded a large concentration of unrecognized shark eggs, next to swarms of black-brown catshares, suggesting that the eggs themselves are of the same species.
The discovery emerged during the last survey Marine The Holland 1 Remote Control as part of INFOMAR, a joint venture between the Marine Institute (MI) and the Irish Geological Survey jointly funded by the Irish Government and the European Maritime and Fisheries Fund. INFOMAR aims to create "integrated map products of the physical, chemical and biological properties of the seabed in the coastal area".
This shark was found during the three-week survey "Searover" (Sensitive Ecosystem Analysis and ROV Exploration of Reef habitat), which took place in July.
"This discovery shows the importance of documentation of sensitive marine biotopes and gives us a better idea of the biology of these beautiful animals and their ecosystem function in the biologically sensitive area of Ireland," explains David Oulo Sullivan, head of research at Searover.
"It was unbelievable," he continued, talking to The Guardian, "the real David Attenborough. This is the main biological finding and the story of this size would be on Blue Planet if they knew it," he said. "There is very little known about deep-sea nursery schools globally."
The eggs were laid on dead coral skeletons. According to the above video, coral reefs can provide a shelter for newly-created sharks.
In addition to the huge number of black cat cataracts, the drone also managed to capture the shots of the rare species of Sailfin, a species that could potentially exist to grow egg cases.
The Searover survey was the second of three planned surveys. The team hopes to come back next year to get a footage of their eggs.
