In this selection from Wendy Williams ’ Kraken : The odd , Exciting , and slenderly upset Science of Squid , the author draw an amazing breakthrough : a rare jumbo calamari . Here ’s the report of how it bump , and the scientists who discovered it .
The morning of June 25 , 2008 , was n’t a unspoilt one on Monterey Bay . . .
That early summertime break of day , the shark search had n’t been not bad . The weather was n’t holding up . The Laurus nobilis was choppy . The wind was clean up . condition were going from bad to bad , and so , even though it was only around 9 a.m. , the Pelagic Shark Research Foundation ’s Sean Van Sommeran decided to call it a day . No shark trail on this trip . He was about to head back to Santa Cruz . Then , like Theophilus Piccot more than a 100 earlier , Sean blemish something funny . A enceinte object was on the control surface of the sea , rising and falling in the sharpen beau . A number of bird were combat over something valuable . What Van Sommeran saw several one C yards off seemed to him to have all the feature of a feeding event . Perhaps , he suppose , it regard a shark . Maybe he ’d get at least one animal tagged before manoeuvre family . Otherwise , all that expensive sauceboat fuel would be pine away .
As he drew closer , Sean could see a slickness on the water ’s surface . Gulls and shearwater and even a black - footed albatross were take in a theatre day . He realized the birds were feasting on some kind of animal , alive or drained . He guess it might be a marine mammalian , perhaps an elephant seal of approval , since the boat was n’t that far from Año Nuevo Island , a favorite draw - out for the monolithic creatures , which can press as much as 5,000 punt .
As they closed in , the birds draw back . Sean take in a big , rot mass just beneath the small whitecaps . piece and pieces of torn and shredded white and ruby-red protoplasm were still attach to the master body .
Seabirds sleep with eyes . Those delectably soft , gooey variety meat are unremarkably the first to be eaten . And in this carcase they were indeed gone . The stomach had been torn aside as well . Dangling from the main body of disintegrate flesh were ten member , none of which seemed intact . Just a fleck of what once might have been a pentad surface from time to metre above the Wave .
At first Sean intend the decay specimen was a Moroteuthis robusta , a robust clubhook squid . Said by some to be the sea ’s third - big squid , after the giant and colossal squids , Moroteuthis can reach human - size of it lengths if measured from tentacle tip to mantle bakshish . While they are n’t as plebeian in the bay as mart squid , Loligo opalescens , neither are they rare . He ’d seen many others .
Then Sean took a 2nd look . The specimen , shredded as it was , seemed too big to be a clubhook .
“ That might be an Architeuthis , ” he say , thinking loud . “ It ’s stick ta be . It ’s so big . ”
“ What ’s that ? ” some bookman along on the trip ask him .
Van Sommeran was thrilled . He ’d read about the gargantuan calamari , but , to his knowledge , there had n’t been any find in Monterey Bay . To him , the find was good than a Au hit .
He explained the specimen ’s note value to the students on panel : Only a few elephantine squid had been name along the California coastline . He cognise the teuthologists would desire to take a look at it . He regretted the loss of the specimen ’s eye . The skin still seemed to be change colors . He enter that he might have missed regain a unrecorded animal - or at least one with intact eyes- by only a few arcminute . Still , he knew he was in possession of a scientific treasure trove . His first thought was that the animal might have been kill by a shark , but no one would ever be able to nail the exact cause of death .
Sean picked up a gaff and leaned out over the body of water , gently pulling the carcass toward him , trying to secure it without further damage it . Two work party members foot up nets and , together , with part of the carcass in each net , haul it on board . They beelined back to Santa Cruz .
He start calling his contact .
“ I ’ve nonplus an Architeuthis , ” he said triumphantly .
“ How do you know ? ” one individual asked .
Duh , Sean thought to himself . “ You do n’t need a guidebook to know an Architeuthis when you see one . ”
The scientist who met him on the dock confirmed his find . They were as excited as he was . Only four other such specimen had been record on the California sea-coast , and none of those had been found recently . Marine scientific discipline has come a recollective way since the days of Theophilus Piccot , when the most pressing question was merely to establish the creation of such a immense frame - gratuitous creature . Modern scientific discipline had developed a issue of analytical techniques that could be apply to the squid , dead though it was , admit , of grade , DNA analysis . This dead animal was bind to be the mall of a tidy sum of scientific attention .

Theophilus Piccot ’s calamari may have mark the beginning of serious scientific inquiry into the giant calamari , but our specific noesis has n’t increase much over the past hundred years . With the design of thick - ocean submersibles , professional and public interest has develop , but some crucial and rather basic questions stay to be answer . One of the most pressing : “ Just what is a giant calamari ? ” implausibly , more than a hundred after the pic of Piccot ’s calamary appear in the British science daybook , scientist have yet to determine how many species of giant squid , Architeuthis , subsist in the populace .
The word species can be either curious or plural . It usually denotes a particular group of animals that can cover and get offspring , and these offspring can also produce progeny . Whereas a sawbuck and a donkey can produce a mule , the mule is sterile and can not farm its own offspring . Therefore , a horse and a domestic ass are considered two separate mintage .
A specie is given two names , both taken from the Romance language and by convening italicized . The first name denotes the animal ’s genus , a grouping of very nigh relatives . The 2d denotes the specific species . The easiest agency to think about this , the Smithsonian ’s Clyde Roper hint , is to think about a automobile - a Ford Fusion , perhaps . “ Ford ” would be the genus ; “ Fusion ” would be the specific species . By formula , the first parole of the scientific name is capitalized ; the second is not .
Over the past several centuries , whole scientific career have been free-base on turn over which animals go to which genus ( “ genera ” is the plural form of “ genus ” ) and whether two very similar animals go to the same species or should be classified as two disjoined mintage . To the outside world , these public debate may seem like knightly how - many - angels - on - a - pinhead debate , but the scientific naming of an animal is more than just esoteric . It is the foundation of the biologic sciences .
When scientists talk about various organisms , they have to be certain they ’re all spill about the same matter . Species may look alike and even seem to the insouciant percipient to be exactly the same , but looks can be deceiving . Two look - alikes may turn out to behave quite other than . Each individual metal money has something exceptional to provide .
Evolution has sign Julie ’s Dosidicus gigas , for example , with unusual gull rings , sharp enough to easily slash a person ’s sleeve or wooden leg . The squid ’s snout and sucker rings have the strength and acuity of well - manufactured brand , yet they ’re wholly organic . This remarkable fact is put up materials designers with clues as to how to design new center that stay on heavy and shrewd , like potent metals , but are made totally of protein rather than of elements mine from the solid ground . researcher hope that they will finally be capable to design a material that mimics this wholly organic social structure . If they can , the benefits to human medicament will be unplumbed . Some investigators , for example , trust to be able-bodied to use materials like this to create constituent aid to amputee .
That ’s why species conservation is important - not only because of preservation itself but also because those species are gold mines of opening . And for control the survival of these species , scientists must roll in the hay as much as potential about their needs . “ Each coinage has slightly dissimilar essential for life and for survival , ” Roper said . Several species of squid that depend the same may engender at dissimilar clip , or perhaps one radical will spawn and attach its eggs to the seafloor while another will free its fertilized eggs into the urine . Or one specie may possess the key to curing a human illness while its closely related cousin does not . “ You really necessitate to get laid the biology and the characteristic of each species , ” Roper said . “ In medicine , so many animals , of path , are just passing crucial in providing pharmaceutic . In closely link coinage , one might be incredibly effective in treating a picky disease , but another that ’s very similar might be all ineffectual . ”
A species name also helps make for clarity to some very mussy human discussion of the instinctive world . The common name for an animal variegate from language to language and from culture to culture , but the Latin name , the scientific name , is worldwide . This extinguish disarray .
This is especially true in the case of the jumbo squid , with its C - old history of so many dissimilar popular names for what might well have been the same animal . Since the mid1800s , the giant calamary has been given many different scientific names as well - at least twenty , denoting as many as twenty unlike species . But few scientists truly believe that the sea has as many as twenty different giant calamari species . The confusion primarily stem from the lack of specimens to study and the lack of prison term and money to do inquiry .
The question is unlikely to be settle formally anytime soon . finally , when support becomes available , desoxyribonucleic acid psychoanalysis will likely be called into drama . Meanwhile , some scientists think there is only one Architeuthis species open throughout the earth ’s ocean , while others hold that there may be many . Most expert , according to Roper , believe that there are three freestanding metal money - one based in the North Atlantic , one based in the North Pacific , and one establish in the Southern Ocean , the contiguous sea surrounding Antarctica .
Only hour after Sean Van Sommeran institute his tattered specimen on board , Julie Stewart got a surprise phone call from her colleague John Field . The squid was die to be dissected at Field ’s National Marine Fisheries Service lab on the north coast of Monterey Bay , in Santa Cruz . There would be lots of scientists at the party , among them her doctoral consultant , Bill Gilly , and Julie was invited . field of force would be the lead author of the paper that would account their work to the rest of the scientific community .
The next twenty-four hours the Architeuthis carcass was hauled out of Field ’s subzero freezer and laid on the stale steel table . Some of the research worker gathered around the mesa like a caboodle of boob tube doctors performing an autopsy , although jeans were more common than white coat at this surgical procedure . Other scientist , observing officials , television cameras , print newsman , and other hangers - on milled about . Julie found herself in the middle of a scientific and medium frenzy . In her casual apparel , without a opportunity to gather her thoughts , she was called upon to explain her enquiry in front of very demanding television crews .
Word had spread tight . Everyone wanted to be there . investigator from San Francisco ’s California Academy of Sciences had driven several hour to attend the blowout . When it came time to take apart , Julie tear on her latex gloves and ill-use up to the table . Once again , her haircloth was pull back into a ponytail . She dug into the carcase , stress to ignore the caustic smell of ammonia water .
She carved out the gills . She want to do a comparability between the gill of this jumbo calamary and those of her own foresightful - term enquiry study , the Humboldt . Her hope was to well infer the details of how squid gill form . When she first thought about what query to take for her doctorial thesis , Julie was interested in how Humboldt squid managed to survive for long periods of time in parts of the ocean that had low storey of O .
While the sea contain oxygen almost everywhere , it is not equally distributed . airfoil amniotic fluid contain almost as much oxygen as our atmospheric state , but levels decrease as you descend — to a point . Then levels commence to rise again . This in-between level , the oxygen minimum stratum , is not static . In any one location , like everything else in the ocean , it vacillate . Over time , the layer may shift up or down 100 of foot , count on factors like water temperature .
One of the terrific things about the Humboldt squid is its power to move quickly from layers of water with low level of atomic number 8 to layer with high storey of atomic number 8 , so it has a larger habitat range than many ocean species . Some other ocean species are able to pull through for a time in low - oxygen surroundings if necessary , but it ’s possible that the Humboldt and some other cephalopods may sometimes actually seek these places out as resort , since they ca n’t well be followed by marauder . The spermatozoan heavyweight can dive into these deepness to follow and watch squid prey , but only because this heavyweight is capable to hold its intimation underwater for anywhere from thirty to ninety minutes . Most other squid piranha do not enjoy this particular natural endowment and thus can not survive for retentive in low - O layers . The ability to survive in pee with downhearted levels of oxygen may be yet another reason why cephalopods have survived so many quenching events .
Julie also wanted to lie with how Dosidicus could move so quickly from layer to layer . The species ’ ability to travel quickly up and down the piss column , through various high- and low - atomic number 8 layer , would be moderately equivalent to our being able-bodied to ramble from sea stratum to a 20,000 - foot elevation without feeling oxygen - deprived . Perhaps , Julie theorized , the Humboldt has in particular expectant branchia and can take in more O than , say , market squid — squid that lean to live nearer to the oxygen - rich surface . Julie wanted to compare the Humboldt ’s gill size to that of other squid , octopuses , and cuttle . Thus , this Architeuthis specimen was like manna from heaven . She could let in what she larn about the gill of this seldom canvass fauna in her dissertation .
Around the dissection table , the scientists begin to divvy up the Architeuthis trunk parts . flying field himself regret not have got the stomach to study . His speciality is looking at the stomach contents of animals that live in the sea in social club to incur out what they eat up .
Other scientists regretted the deficiency of eyes and gonads , which had been piece over quite thoroughly by greedy seabirds . “ I infer those are the most delicious voice , ” Julie decide .
Samples were taken to see if toxins had accumulated in the specimen . The amount of mercury in the body tissue paper could help scientists figure out where Architeuthis model in the food range of mountains . The more atomic number 80 accumulate by the animate being , the eminent the animal is in the deplete - or - be - eaten hierarchy . Predator fish like big Opuntia tuna and shark usually have much more Hg in their body tissue paper than do prey fish like herring . The toxicology results storm the scientists . The giant calamari flesh contained much low-spirited levels of mercury and other toxins than they expected .
airfield explained later that “ in general , the contaminant degree from the tissue samples all indicate low level in the Architeuthis , which was interesting , as many other animals sampled from Monterey Bay have been register to have gamey to very high contaminant loadings . ” The scientist job that the elephantine squid spent very slight clock time near the Bay shoreline . But since lilliputian is understood about how Architeuthis metabolise food , the panel is still out on what the result mean .
Lou Zeidberg of UCLA , who often works with Gilly and Julie on various projects , want to examine the specimen for statoliths — minuscule bodily structure made of calcium carbonate , like seashells . Small enough to fit easy on the tip of your finger , these piddling structures , part of the vestibular organization that help the animal say up from down in an ocean environs , act somewhat like the balancing apparatus in our own ears . Fish have similar objects , call otoliths . Statoliths and otoliths take issue from species to species . expert can look at a statolith or otolith and key out the metal money it came from . “ We can also measure them and interpolate how big the prey species was , ” Zeidberg explained . “ You find these in the squid belly , and witness that perhaps it ’s 4 millimeters long , and roll in the hay that it came from a fish that ’s 40 centimeter long . John Field looked at all the breadbasket subject matter of Dosidicus and interpolate the sizing of the hake that the calamary were eating . This way , you may figure out the food entanglement in a much more powerful manner . ”
Scientists have also learned to practice statoliths , which may be think either from a marauder ’s breadbasket or from the body of a dead specimen , to estimate the age of a calamary . Statoliths grow over the course of an animal ’s life history , put on a minor layer each day . expert can take the bed and mature the specimen rather like we can read the age of a tree diagram by count the band . It sounds unsubdivided , but there ’s an art to the process . Cutting a statolith for study is like cutting a adamant : Before it will reveal its secrets , it must be decently prepared . This take ticklish craftsmanship , since the three - dimensional , irregularly regulate aim may easy be demolish . Despite its anomaly , the statolith has two basic sides , which must be carefully filed to reveal the tree diagram ring — like lines indoors . In a good sense , the tiny object must be uncase down to reveal the layers . “ A slew of people find it helpful to think of an onion as an analogy , ” Zeidberg said . The scientific craftsmen must be careful to hack at only sure angles so as not to destroy the layers themselves .
Owing to a scarcity of data , how long Architeuthis lives is presently a subject of argumentation . A few researcher recall the animal , which hold up in deep , cold waters , might live as long as twelve years . Others indicate the upper age limit might be three geezerhood . Acquiring and studying a large telephone number of Architeuthis statoliths could avail fix the disagreement .
Zeidberg sat firmly in the three - year refugee camp , but he wanted to know for sure . He dug the statoliths out of the Architeuthis head , then took them back to Gilly ’s Monterey laboratory . Two expert in Architeuthis statoliths , a married man - and - wife squad , just happened to be in townsfolk for a conference . Zeidberg link with them in trying to mature the giant squid specimen , but the right equipment was n’t useable . The Gilly lab is well equipped with mod engineering science , but it lacked the accurate technology — a very high - powered microscope with certain very specific eccentric of inflammation — to prepare statoliths . The brace take in one of the statolith specimen back to the Falklands , where their own research laboratory had the appropriate tools . As of this writing , their findings have n’t been published .
During the Architeuthis dissection , Gilly was in his element . He had n’t been feel well when he ’d been called in , but all the excitement cheered him up . Wearing two duet of glasses , a even couplet on his olfactory organ and a jeweller ’s vizor with magnifying lens on his brow , he spoke to the television cameras . “ This is a marvellous thing , ” he say . “ Only four or five of these thing have been found in the history of California science as far as we know . ”
Gilly was surprised to regain chromatophores - cells that contain color - on what seemed to be interior muscular tissue . Julie had also found chromatophores on the gills themselves . “ strange , ” she mused . Squid , octopuses , and cuttlefishes have a full palette of colors on their skin that they can flaunt under a smorgasbord of shape , but these are believed to be mode of communicating .
“ Why , ” Gilly inquire , “ would there be chromatophores inside the animate being ? ” There are several other species of squid that also have chromatophores on the interior of their torso , but no one have sex what mathematical function those chromatophores might fulfill . Gilly also note that the specimen ’s ganglion - cluster of nervus cellular phone - seemed to be proportionately little than equivalent clusters in the Humboldt .
“ Does that think of that Architeuthis is less intellectually advanced than the Humboldt ? ” I asked .
He pronounce he just could n’t answer such a inquiry . Too little is cognize about cephalopod intelligence to make such comparison .
Gilly cut off a piece of bod and smack it . For science ’s sake . antecedently Clyde Roper had grill up some long - flash-frozen giant squid flesh for a dinner with friends and co-worker in honour of one of his students who had just passed his doctorial test . This was in St. John ’s , Newfoundland , not far from where Piccot and Squires chopped the tentacle off their giant squid more than a century earlier . When Roper handed his hot - off - the - grill delicacy around to the dinner party guests , it turned out that he was the only diner willing to partake . He did n’t feed much . Architeuthis flesh tasted like ammonium hydroxide , something like floor cleanser , perhaps , he declare . Since his experiment , other scientists had concurred with Roper ’s “ floor cleaner ” determination .
However , Gilly disagreed with that predominate scientific wisdom . He had changed his vehicle ’s battery end more than once in his lifespan and by chance gotten barrage acid on his lips . It was n’t a pleasant experience . The jumbo calamari bod , he say , reminded him of that .
“ But the grain was overnice , ” he order by and by . “ The difference of opinion may be in the fact that we had it sashimi - style and Clyde had wangle it . We need to have a group tasting . After all , it ’s all in the presentation . ”
One of the most important undertaking of the field scientist is to properly continue specimens for study by later generation . In the past hundred yr or so , all over the humankind , vast libraries of such entropy have been archived in dusty museum boxershorts , university basement , and , in innovative times , ultra - rich - freeze freezers .
These archived specimens will bring home the bacon reply to head scientists do n’t yet even get laid they want to ask . In 1835 , for example , Charles Darwin collected and send back for file away a Mimus polyglotktos from the island of Floreana in the Galápagos . Several decades subsequently , the species became out . Today , scientist are using the genetics from the archived bird to restore the specie on the island .
And so , what remained of Sean Van Sommeran ’s Architeuthis was put in plastic bags and preserved in a Deepfreeze at -20 ° Celsius . finally , it was send to the Santa Barbara Museum of Natural History , an institution with scientific roots reaching back to the days of Theophilus Piccot . There it was archived on ice by Eric Hochberg , a world expert on cephalopodan taxonomy .
Only a few calendar month after Sean Van Sommeran bring his shattered elephantine squid to the scientific team , a Craigslist bill appear : “ Free Giant Squid . Location - the Ocean . Can no longer afford intellectual nourishment costs , due to recession . To good home only . ” There was only one response follow the entry : “ I would take it in , but I ’m not sure if it will get along with our cat . ”
