New shark nursery off Ireland

Have you ever heard the saying "If you think of something hard enough, it will materialize"? Anyway, it's something that goes in that direction. Well, the catchy song "Baby Shark", associated with IKEA's stuffed sharks making waves on the internet, has inspired many people to think about these animals. The announcement of the presence of baby sharks near the home of IKEA (somehow …) combines these two sensations Internet in a surprising discovery.

Extraordinary results were announced at the INFOMAR Seabed Mapping Seminar in Kinsale, featuring sequences captured by the Marine Institute Holland 1's Remote Control Vehicle (ROV). Chief Scientist David O & # Sullivan INFOMAR and the chief scientist on the analysis of sensitive ecosystems and exploration by ROV The Reef Habitat Survey (SeaRover) revealed: "We are excited to report the discovery of a rare shark nursery on a scale never documented in Irish waters. No pups were evident on the site and it is thought that adult sharks could use degraded coral reefs and exposed carbonate rocks on which to lay their eggs. A healthy coral reef nearby can serve as a refuge for young juvenile sharks once hatched. Further study of the site is expected to answer important scientific questions on the biology and ecology of deep-sea sharks in Irish waters. "

Located a little over 300 km northwest of Galway, Ireland, a nursery containing thousands of egg cases was captured on a video taken by the ROV deployed by scientists aboard ILV Granuaile. This shark nursery was observed in one of six special conservation areas located in Irish waters, at a depth of about 750 meters. Scientists were not specifically looking for a shark nursery, the mission of this expedition being focused on exploring Ireland's deep ocean territory, including deep-sea coral reef systems. The discovery of these eggs – called mermaid handbags – was recorded this summer and the researchers analyzed the footage and other data obtained since.

Marine researchers described this facility as a very rare shark nursery because of high egg concentrations. According to scientists, these huge amounts suggest that female sharks could gather in the area. A coral reef located nearby will serve as a refuge for baby sharks (called puppies) when they hatch. But what species of sharks did these eggs belong to? A lot of black-mouthed catshark (Galeus melastomus) were present in this nursery, which we assume are responsible for these eggs. These sharks are common in the North-East Atlantic and, as such, are assessed by the International Union for the Conservation of Nature (IUCN) "Least Concern" and having a stable population.

They are fine sharks with striking colors, while the inside of their mouth is, as you might have already guessed, black. With a pattern of dark spots and stool on their upper face (called "dorsal face"), it contrasts strikingly with their snow-white belly. Black-mouthed cats are not large sharks with a recorded maximum length of 90 cm (2.95 ft), with individuals being more often measured between 60 and 80 cm (1.96 to 2.62 ft). Shark scientists have largely talked about the black-mouthed catshark in 2017, as it was found that a microplastic ingestion (<5 mm) had been recorded in this species around the Balearic Islands. Of the 125 individuals analyzed, 16.80% of the samples had ingested microplastics. The effects of plastic pollution on sharks have already been discussed in a previous Forbes article.

If that were not enough, the film also recorded a lonely loner: the roughshark Sailfin (Oxynotus paradoxus). This rare shark can reach a length of 1.2 m (3.93 feet) and is considered "data deficient" by IUCN because of its lack of knowledge of the species as a whole. It is one of only two species of the genus Oxynotidae sharks, found in the North-East Atlantic, from Scotland to Cape Verde Islands and Cape Verde. in the Azores. Observed during their travels on the continental slopes of the Atlantic, the people involved in the project think that this lonely predator at the particular pace may have used this nursery as a feeding place … but not for feeding adults. Some sharks are known to feed on the eggs of other sharks, which is perhaps why it was hanging around the nursery. No eating behavior was captured on the video.

"Both species are of scientific interest as Ireland has the obligation to monitor deep-sea sharks under the Marine Strategy Framework Directive," said Maurice Clarke, of the marine advisory service. fishing ecosystem of the Marine Institute. The discovery of this special habitat highlights the value of seabed habitat mapping. The Marine Institute explains that these areas are home to various forms of marine life, including sea fans, sponges, worms, starfish, crustaceans and a diverse fish. This was the second of three shipments funded by the government and public bodies, as well as the EU's European Maritime and Fisheries Fund.

I guess all of us, especially those from Ireland, are going to sing a little longer about baby sharks.
