Drone shots of a rare shark nursery found 200 miles west of Ireland were revealed. It is a discovery on a "scale that has not been documented in Irish waters."

The material showed a large number of chicken eggs that were not caged, next to schools of black-footed catfish, suggesting that the eggs themselves were of the same species. 19659006] The discovery took place during the most recent survey by the Institute's Remote Control Vehicle Holland under the INFOMAR Program, a joint venture between the Marine Institute (MI) and Geological Survey of Ireland, jointly funded by the Irish Government and the European Maritime and Fisheries Fund. The aim of INFOMAR is to create "integrated mapping products of the physical, chemical and biological characteristics of the seabed near the coasts".

This shark nursery was found during a three-week survey on "Searover" (Sensitive Ecosystem Analysis and ROV Habitat Exploration), which took place in July.

"This discovery demonstrates the importance of documenting sensitive marine habitats and will give us a better understanding of the biology of these beautiful animals and their ecosystem function in Ireland's bio-sensitive area," said David O & Sullivan, chief scientist of the Searover survey.

"It was incredible," he continued The Guardian, "True David Attenborough Junk. This is a significant biological find, and a story of this magnitude would have been on Blue Planet if they had known about it," he said. "Very, very little is known globally about deep-sea horticulture."

The eggs were laid on dead coral skeletons. According to the video above, coral reefs can provide shelter for newborn sharks.

In addition to the large numbers of black-mouth cat sharks, the drone also managed to take pictures of the rare reef shark Sailfin, a species that could possibly be involved in the search for the egg cases.

The Searover survey was the second of three planned surveys. The team hopes to return next year to get an idea of ​​eggs hatching eggs.
