Rarely - learn deep - sea shark have been spotted mysteriously gathering off a seamount near Panama — the first time the mintage has ever been documented in the surface area .
In a study published March 8 in theJournal of Fish Biology , scientists confirmed the " atypical " gathering of 12 prickly shark ( Echinorhinus cookei ) in the Cordillera de Coiba , Pacific Panama — a 26,000 - solid - mile ( 68,000 square kilometers ) offshore devil dog protect area that includes nine deal cooking stove , 24 seamounts and a 15,568 - foot - deep ( 4,745 meters ) trench .
Cordillera de Coiba, Pacific Panama.
The elusive pricklysharks , which have bodies covered by burry , modified tooth , grow up to to 13 foot ( 4 m ) long and may dwell depths of up to 3,280 feet ( 1,000 m ) . " They favour to be in deeper waters , " which makes them difficult to abide by , analyze authorHéctor Guzmán , a maritime ecologist at Smithsonian Tropical Research Institute , told Live Science . Although data on the distribution of this specie is scarce , they have been respect from Oregon and Japan in their northerly cooking stove down to Chile and New Zealand .
Scientists consider these gatherings , which take place in May 2022 between 495 and 1,146 foot ( 151 to 350 m ) deep , were " careful . " . Before this find , there had been no evidence that these sharks aggregate . The researcher are n’t sure why the shark were come together , but it could be to do with feeding . " We check juvenile shithead down there and those are easy targets for the prickly , " Guzmán said . It could also be link to reproduction . The team checked the sharks ' claspers — alter pelvic fins used in reproduction — to confirm that both manful and female shark were at the gathering .

The researchers observed the gatherings as they explored two seamount on the Cordillera de Coiba , not far from Colombian body of water , during 11 nosedive in a three - person submergible — with a television camera and automatonlike weapon to pick up samples .
Confirming the front of prickly shark around these seamount is important for the preservation of these biodiversity hot spot . " It helps us to justify why we ’re protecting these extremely productive scheme , " Guzmán state , because focalise on protecting the whole home ground would , in turning , help all the species that use it .

But although the seamount is located inside a no - take zone — where no sportfishing is allowed — the researchers meet a Colombian vessel illegally fishing nearby for two consecutive day . " We get mental imagery of the back of [ the watercraft ] where they had plenitude of fins of several species of shark " and reported it to the Colombian authorities , he say .
This foreground an important issue . Although the area is protected , it ’s located in the opened ocean , far from the coastline . " There ’s no way you could have a patrol boat with a couple of rangers in that country , " Guzmán said . This is why their project use satellites to monitor sportfishing , to apply protections that are in space on paper , he sum .
