When plunk into the deep with the assistance of remotely operate vehicles ( ROVs ) , marine scientists have a rarefied chance to blot mintage that we humanity would otherwise go our whole lives never seeing . One such rare deep ocean beastie is the whalefish , a bright scarlet fish of the orderCetomimiformeswho was recently get   on camera for your view pleasure .

Spotted by theMonterey Bay Aquarium Research Institute ’s ( MBARI ) ROV Doc Ricketts alongside Steve Haddock and his team on their recent R / 5 Western Flyer hostile expedition , the whalefish was look cruise along at a depth of 2,013 meters ( 6,604 feet ) in offshore Monterey Bay .

“ We ’ve only encountered these hidden fish 18 time in 34 geezerhood of deep - sea exploration with our remotely run vehicles ( ROVs ) , ” wrote the MBARI in aFacebook mail .

While they are a rare sight and little bang to the enquiry community , what we do know about whalefishes establish that they are really quite unknown , even by the standards of the already bizarre benthic .

“ The “ shapeshifter ” name refer to the three unlike body chassis that were observe in net income - caught fish , ” say Dr Steve Haddock of the MBARI to IFLScience . “ These are not vary frame forthwith , but they change as they grow from babies to grownup , and males calculate very different from females . There are hatful of object lesson in the ocean — even among jellyfish — where two different stages of exploitation are thought to be two unlike species , until someone can tie in the Lucy in the sky with diamonds . ”

It ’s well-heeled to see why connecting the three acid of whalefish proved take exception when you find out quite how dramatically this fishes ’ form changes throughout its animation . consort to MBARI , whalefish start life in their larval form with functional eyes , but as they progress to adults the electron lens is lost , and they lose the ability to see .

luckily , they ’ve got a backup sensory electric organ in the form of a lateral course festooned with sensorial pores . These enable them to “ see ” by detecting vibrations in their surroundings , arguably a more effective way of navigate your surround when that environment seat at a deepness where light is in short supply anyway .

What happens to the whalefish trunk programme as it maturesdepends on their sex activity . The grisly fate for males attend their jaws dissolve into nothing , a right matter too since they also lose their esophagus , bowel and intestines . They fix for the change by englut on copepods so that as their body fills with sexual organs it also pay off a surge in liver tissue paper which acts as an energy author for the whalefishes ’ sperm delivery armed service while it ’s ineffective to eat . They ’ll partake their sperm with whoever will take it until their energy run out and they die .

Females also undergo their own makeover , instead ballooning to a shape that mime that of a baleen whale ( hence the name ) . They also become what would be a dazzling shade of orange - bolshie if it were n’t that light of this wavelength does n’t penetrate the water column to their deepness , so this conspicuous coloration in reality lead them near - unseeable in their environment .

So , what did we acquire from this encounter ?

“ I do n’t intend we discover anything new scientifically , but I do think we were able-bodied to get the highest - resolution video thus far of a live specimen , ” continued Haddock .

“ Too often you see the damage unnatural corpse of a net income - captured bass - sea animal . Even inFinding Nemo , the anglerfish was show withgray , opaque eye , indicating that it was modeled on a dead specimen . I opine showing the organisms in theirtrue sizeable stateis important for aid people value deep - ocean animal a bit more . ”
