research worker explore an ancient , submerged volcano off the Pacific sea-coast of Canada have come upon it is still dynamic — and " covered " in thousands of giant egg .
Before the pleasure trip , the squad thought the vent was extinct and the waters around it frigid . However , they establish the underwater mountain — which loom 3,600 feet ( 1,100 meters ) above the seafloor — spouting warm water supply and encrusted with deep - sea corals . The hot , mineral - rich fluid keeps the surrounding body of water toasty , providing idealistic conditions for some marine creatures to survive in the mystifying ocean . The research worker were even more surprised to see a Pacific white skate ( Bathyraja spinosissima ) weaving in and out of the frond and laying egg on the summit , near a mile ( 1.5 klick ) beneath the aerofoil .
The summit of the seamount was covered in thousands of giant, ravioli-shaped eggs.

" It ’s a really exceptional place on top of a really peculiar place,“Cherisse Du Preez , a deep - ocean nautical biologist with Fisheries and Oceans Canada and principal investigator on the expeditiousness , say Live Science in an electronic mail . " The onlyprevious finding of a Pacific white skate nurserywas in the Galapágos and I opine was on the order of a dozen or two nut . "
Du Preez say the recently encounter skate nursery is many times the sizing of that . " I ’d estimate the elevation of the seamount , which was cover in eggs , had — I do n’t know — 100,000 ? A million ? " These eggs were large , Du Preez tot up , measuring about 1.5 understructure ( 0.5 m ) across .
Researchers recorded the first ever footage of a female Pacific white skate (Bathyraja spinosissima) laying eggs.
The investigator were also the first ever to record footage of a peaceable whitened skate place eggs , they said in avideo of the expedition .
Pacific white skate are little - known sea creatures bear on to sharks and rays . They are among the deepest - dwelling specie of skate , populate depths between 2,600 and 9,500 feet ( 800 to 2,900 molarity ) off the west coast of North and Central America , allot to theIUCN Red List . grownup female , which can grow up to 6.5 foot ( 2 m ) long , place orthogonal bollock , which are sleep together as " mermaid purse " because they reckon like little bags , Du Preez said .

In 2018 , researcher discovered several of these cappelletti - shaped testicle close to hydrothermal release near the Galapágos Islands , intimate skate moms rein in the volcanic warmth to incubate their eggs . The new observations point to the same conclusion , Du Preez say .
" It takes four eld for the unseasoned to acquire , " she explain . " The strong water likely speeds up the gestation period of the eggs , resulting in more successful juvenile . The shallow crown of the seamount is almost a coral garden and a safe glasshouse for juveniles to grow before they descend to the deep — it ’s a winnings - winnings . "
The researcher will retain to supervise the bollock - cover seamount , which is not presently protected and may be jeopardize by sportfishing activities . The find demonstrate just how authoritative vent home ground are as nurseries and to the overall health of the ocean , Du Preez articulate .
