Shots were discovered of the drill of a regular shark nursery, found 200 miles west of Ireland. This is called a discovery on a "scale not previously documented in Irish waters."

The recordings showed a high concentration of untreated egg sharks, in addition to the birth of black cats, indicating that the eggs themselves were the same species.

The discovery was made during the latest research Marine The Institute is a remote-controlled Holland 1 vehicle within the INFOMAR program, a joint venture between the Institute of Maritime Studies (MI) and the Geological Survey of Ireland, jointly funded by the Irish Government and the European Maritime and Fisheries Fund of the EU. The goal of INFOMAR is to create "integrated products for mapping the physical, chemical and biological properties of the seabed on the nearby coast."

This shark nursery was found during a three-day "Searover" survey (Survey of Sensitive Ecosystems and ROV Reef Research), 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 functions in the biologically sensitive area of ​​Ireland," explained David O'Sullivan, chief researcher of Searover.

"It was incredible," he continued, talking to The Guardian, "the things of David Attenborough." This is a great biological discovery, and the story of this size would be on the Blue Planet, if you knew about it, "he said." Very, very little is known globally about nuts from seawater. "

The eggs are placed on a dead coral skeleton. According to the above video, coral reefs can provide shelter for newly born sharks.

In addition to the enormous number of black-and-cats, the drones managed to record images of the rare Sailfin's cheese, a species that could potentially be there to feed eggs.

Searover's research was the second of three planned research. The team hopes to return next year to try to shoot the eggs that come out.
