Ocean Rover discovers rare shark nursery off the Irish coast



A rare shark nursery was discovered in deep-water coral reefs about 200 miles west of Ireland.

Material taken in July from a Remote Control Vehicle (ROV) shows an unusual number of ova (820 yards) below the sea level about 750 meters away.

According to the Irish Marine Institute, such large concentrations are "rarely detected" and suggest that women in this area can gather to lay their eggs.

"We are pleased to report the discovery David O & # 39; Sullivan, chief scientist of the SeaRover (Sensitive Ecosystem Analysis and ROV Exploration of the Reef Habitat) study, last week.

This discovery demonstrates the importance of documenting sensitive marine habitats, "he continued," and will give us a better understanding of the biology of these beautiful animals and their ecosystem function in Ireland's biologically sensitive area "(196590) 02] O & Sullivan is a member of INFOMAR, a 20-year governmental initiative to map the physical, chemical and biological properties of the Irish Seabed.

A Great Black Sea Cat School Galeus malestomus ] To swim around the grounds suggests that the eggs belong to this species, which is common in the northeastern Atlantic.

The reef shark fin ( Oxynotus paradoxus ) – a type of dogfish was also observed.

"Both species are of scientific Interest, as Ireland is obliged to monitor deepwater sharks under the Marine Strategy Framework Directive, "Maur said ice Clarke from the Fisheries Ecosystem Advisory Services of the Marine Institute in a statement.

The latter, who have been classified as "near-threatened" by the International Union for Conservation of Nature, may have been feeding on the eggs, although there is no hard evidence to support them. [19659002] "There were no juveniles on the spot and it is believed that the adult sharks may use degraded coral reef and exposed carbonate rocks to lay their eggs," explained Ouller Sullivan.

"A healthy coral reef in the area can serve as a sanctuary for the juvenile shark puppies once hatched," he continued. "Further site research is expected to include some important scientific questions on biology and ecology of deep water sharks in Irish waters. "

SeaRover is the second of three co-funded and funded surveys by the Irish Government under the European Maritime and Fisheries Fund.
