The drone images of a rare shark nursery, found 200 miles west of Ireland, have been revealed. It is to be called discovery in a "scale not previously documented in Irish waters."

The footage showed a large concentration of peeling shark eggs, along with blackmouth catsharks swarms, which suggests that eggs were of the same species.

The discovery was made during the last survey conducted by Marina The Holland 1 refurbishment vehicle, which is part of the INFOMAR program, is a joint venture between the Marine Institute (MI) and the Geological Survey of Ireland, funded jointly by the Irish government and the EU Maritime and Fisheries Fund. The aim of INFOMAR is to create "products of integrated maps of the physical, chemical and biological characteristics of the seabed in the area of ​​proximity."

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

"This discovery shows 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 the area of ​​biological sensitivity of Ireland," explained David O & S ;, Sullivan, chief scientist of the Searover survey.

"It was amazing," he continued, speaking with The Guardian, "real things of David Attenborough. This is a great biological discovery and a story of this magnitude would have been in Blue Planet if they had heard of it," he said. "Very, very little is known worldwide on deep sea shark nurseries."

Eggs had been placed on dead coral skeletons. According to the previous video, coral reefs can provide refuge for newly created sharks.

In addition to the large number of blackmouth catsharks, the drone also managed to capture images of rarefull sailfin, a species that could be there to forage egg cases.

Searover's research was the second of the three planned surveys. The team hopes to return next year in an attempt to get a scene material.
