Divers spotted two juvenile ocean sunfish (Mola mola) swimming together off the coast of British Columbia.
" They expect to me like very youngMola mola,“Marianne Nyegaard , a marine biologist specialize in sea sunfishes and a research associate at the Auckland Museum in New Zealand , suppose in the Facebook post .
The raw footage , hold by citizen scientist Timothy Manuelides north of Port Hardy in the Browning Pass country , prove two glinting centrarchid accompany by a schooling of widow rockfish ( Sebastes entomelas ) and yellowtail rockfish ( S. flavidus ) . The sunfish float off as Manuelides approached them , waving their long dorsal and anal fins like wings through green , sunstruck waters .

Sunfish grow up to 10 feet in diameter as adults, but these juveniles were five times smaller than that and measured 24 inches across.
investigator note the ocean sunfish on the right was lose a chunk from its tail . They estimated the juvenile measured around 24 inches ( 60 centimeters ) in diameter . mola are thelargest bony fish in the worldand can grow to a whopping 10 feet ( 3 meters ) in diameter , so these juvenile person were about five time smaller than adult centrarchid — but 240 times bigger than their newborn size of just 0.1 column inch ( 2.5 millimeters ) .
Very petty is known about sunfish ' early living , andtheir adorable , bug - size larvaecan only be identified at species storey via DNA sequencing .
Sunfish are also known as mola ( which is also their genus and species name ) , after the Latin word for a millstone , reflecting the round , flatten physique of their body .
The video unwrap that sunfish can swim quicker than many citizenry assume , the researchers note in the Facebook post . " They are often mistakenly think to be slow,“Jackie Hildering , a researcher and the education and communication theater director for the Marine Education and Research Society ( MERS ) who was on the honkytonk but did not see the sunfish , wrote in the post . Hildering added that this perception results from a " sunning " behavior mention at the sea control surface , where sunfish bask in tender lightness after spending time in the inhuman depth .
" They can also be jolly stationary at the surface to present themselves for parasite removal by wench like albatross , " Hildering noted .
Ocean sunfish arefound across the world ’s ocean , from tropic waters to temperate seas , and expend most of their time between the body of water ’s surface and 660 feet ( 200 m ) abstruse . They were long think to be the only coinage ofMolain the northeasterly Pacific , until investigator discovered another metal money — hoodwinker ocean sunfish ( Mola tecta),first draw in 2017 after specimens washed upon a New Zealand beach and later spotted off the seashore of Canada .

To make out between hoodwinker sunfish and sea sunfish , investigator look at the tail , or corn : The tail of an ocean ocean sunfish has a ruffled edge , while the tail of a hoodwinker sunfish is rounded with a central indent .
" This yr it is extraordinary that we know of about seven sightings of mola in the Browning Pass region , " Hildering wrote in the situation . A squad of research worker is working " to influence if they are repeat sightings of the same fish , " she total .
This video is by Timothy Manuelides and was lead to the Marine Education and Research Society for research into the two species ofMolaor Ocean Sunfish off the west coast of North America . Seewww.mersociety.org/mola . Research Lead , Dr. Marianne Nyegaard from Ocean Sunfish Research , name that these Pisces the Fishes are most potential juvenileMola mola(Ocean Sunfish ) , not the otherMolaspecies found in these watersMola tecta(Hoodwinker Sunfish ) .
