A Most Compelling 'Sea Serpent' Case: The Alvin Submersible Encounter

It has been 8 years since the publication of this article, yet it recently reemerged on my radar in the comments of a Twitter post about the most notable of the entertaining, classic stories about mysterious creatures of depths below. My initial response was panic. This article expresses outdated views I no longer hold (I was 16, in high school). I am now pursuing a career in Conservation Biology, and do not wish to be discredited by a childhood belief in literal marine reptile survivors. In this article, I regrettably gave credence to distortions of plesiosaur paleobiology here. I no longer support a literalist interpretation of ‘relict pleiosaur’ sightings. I have retained the enthusing story of the Alvin sighting but entrenched in a critical explanation of sea serpent claims, not rampant speculation that stretches a basis in legitimate paleobiology or geology.
---

While submerged near the Tongue of the Ocean in the Bahamas around July of 1965, Alvin submersible pilot Marvin McCamis allegedly observed an animal which could only be described as reminiscent of the classic 'long necked sea serpent'.1 Accompanied by Captain Bill Rainnie, the two had entered these depths in order to survey the Naval underwater listening array Artemis.1 After descending nearly one mile deep into a crevasse, the pilots allegedly noticed movement and spotted an object which they took to be a utility pole.1 When their position allowed a better view of the object, they realized that it was an animal which possessed a thick body propelled by flippers, a long neck, and a rather snake-like head.1 Before the submersible's cameras could reach the correct angle and activate, the animal quickly ascended and swam off.1 The observation was entered into their logbook, although the two remained hesitant to speak further about it for fear of ridicule.1 While this may sound to be a rather spectacular course of events, those alleged to have been involved in the sighting were all very real. The Alvin, the Naval Deep Submergence Vehicle from which this 'sea serpent' was allegedly viewed, was first commissioned in 1964 from which it made more than 4,600 dives.2 Captain McCamis himself, who passed away in 2004, was assigned as the chief engineer and pilot for the Alvin project after joining the Woods Hole Oceanographic Institution in 1963.3 In 1966, McCamis received a Meritorious Service Award from the Secretary of the Navy for his assistance in the recovery of a lost hydrogen bomb using the Alvin.3 Bill Rainnie, who passed away in 1985, received multiple commendation citations and Navy meritorious service awards for his leadership and undertakings with deep submergence.4

Sketch of McCamis' 'sea serpent' from Without a Trace; the date of 1969 has been proven erroneous by Scott Mardis' 1997 correspondence with Captain McCamis
The Alvin sighting is generally considered to be reliable among 'sea serpent' proponents, as two submersible captains so experienced as McCamis and Rainnie were likely to be competent observers. Still, even such proficient individuals are not infallible to zoological misidentification or eyewitness bias. Could this have been a case of the classic plesiosaurian 'sea monster' motif filling in the gaps of an ambiguous observation? Considering the multiplicity of global reports describing unidentified marine animals which exhibit long necks stretching from bulky flippered bodies, a non-zoological explanation may not be necessary.5 While not all such sightings should necessarily be taken as literal encounters with a radically new animal species, the point as brilliantly stated in Discovering Cadborosaurus remains that:
To dismiss all eyewitness reports as merely anecdotal would be just foolish. In the absence of sufficient material evidence, one can either dogmatically deny even the possibility of undiscovered animals, or look for clues that might help resolve the mystery. ... There are some who would dismiss all such anecdotal evidence, an attitude which smack of dogmatic denial, especially when there is no physical or biological reason for a priori rejection of the possibility of the existence of  marine creatures still unknown to science.6
Scott Mardis has since told me that he sent McCamis a variety of papers which included the Robert Rines photographs, photographs of the Zuiyo-Maru carcass (plesiosaur-like but a decomposed basking shark by all biological accounts), and illustrations based off of plesiosaur reconstructions. The former submarine pilot told Scott that they resembled the animal which he observed.  Although the diligent 'sea serpent' researcher Dr. Bernard Heuvelmans held strongly to the idea of unidentified marine animals being mammalian in identity, he admitted that many reported features do have precedence in reptiles.5 Others contend that the points are little more than special-pleading or improbable picking and choosing of morphological traits. Paleozoologist Dr. Darren Naish has argued that it would be implausible for plesiosaurs, which maintained a conservatively similar body plan throughout nearly 160-million years, to have suddenly evolved neomorphs such as the hairy manes, dorsal crests, fatty humps, and horn-like protruberances reported by alleged long-necked 'sea serpent' eyewitnesses.7  There is also the critical problem faced by all such hypotheses within the Prehistoric Survivor Paradigm: an abnormally large gap in the fossil record remains. Another issue with the relict plesiosaur hypothesis is that the articulation of the zygapophyses in the cervical vertebrae of most plesiosaurs would have prevented much vertical flexure.7 Interestingly, a juvenile specimen of Leptocleidus from Australian Cretaceous deposits was preserved with steeply angled cervical zygapophyses which would likely have allowed it to exhibit vertical neck flexure unprecedented by other recorded plesiosaur specimens.11 As pointed out by biologist Cameron McCormick, this was probably a juvenile condition owing to the degree of cartilage present. 
 Captain McCamis and Rainnie's observation stands as one of the most compelling cases in 'sea serpent' literature, a report not easily relegated to the status of a hoax or misidentification. I recommend Dr. Darren Naish's article on the 'Plesiosaur Effect,' which provides a much more reasonable explanation for reports of long-necked sea serpents, that being that eyewitnesses experienced a sociocultural phenomenon where cultural awareness of the ongoing discovery of fossil plesiosaurs filled in the gaps of poor sightings of known marine fauna, debris, etc. Dr. Darren Naish and others have good work discussing 1) why the idea of relict plesiosaurs is absolutely baseless speculation in light of knowledge and inferences of actual plesiosaur life appearances and behavior, not to mention fossil preservation (see video of pertinent lecture below), and 2) why ‘sea serpent sightings’ likely reflect a sociocultural rather than actually zoological phenomena (also see video of pertinent lecture below). There is no substantial data building a body of evidence for prehistoric survivors or radically unprecedented marine vertebrates. I do think that a skeptical, sociocultural lens holds value for understanding concepts of nature and ‘wilderness.’ Cryptozoological belief may reflect Western optimism in the thick of the Anthropocene that large fauna must have escaped extractive exploration. I’m writing on this soon, and hope that it supersedes my outdated views.

  1. Being born on Lake Champlain in NY, I grew up with stories of Champ. My Grandmother had a close friend who saw Champ and took several pictures. They were at long distance and hard to tell how big Champ was. I remember that friend telling her account. I was mesmerized by the details and was determined go catch Champ. I spent a lot of time on that lake with my family. My Dad worked in Plattsburgh at the AFB and I had to go to Burlington, VT every two weeks for treatment of severe allergies. We either took the ferry, my favorite, or drove the bridge across the lake. I spent every crossing staring out across the waters hoping to see Champ. To this day every time I go home to visit and we cross lake, I still watch the waters. Hard to do while driving.

    I can remember back to a fishing trip we took to a friend's lake property. I was three years old. I remember stomping through the water and weeds with a stick quite clearly even 35yrs later. I don't recall any conversations but the story was I told the friend when asked what I was doing, that I was looking for Champ. He asked what I was going to do with him if I caught him and my reply was "I'm going to boot him in the ass and let him go". That's what happens when you grow up in dairy country.

    I never saw Champ. My Grandma was a no BS woman of short temper. That was one subject she never spoke about. Usually quick to stop any "foolishness", Champ was ignored even though she did not talk about it. I think her friend convinced her she saw something, even though the pictures were hard to see much.

    I fished Lake Champlain year round. Once it iced up enough in the winter we ice fished. I have seen or caught pretty much every fish species in the lake. That lake supports huge numbers of fish, many species being able to reach huge size. Muskies to over 60# and six feet. Sturgeon larger than that. The lake could very easily support a large predator as it still supports man.

    The lake is connected to the salt by several rivers. It drains into the Richelieu River which drains into the St Lawrence. The lake also connects to the Hudson and you can reach NYC by boat from Canada. It would be very easy for a sea dwelling creature to swim into the lake. Once the locks were built, it was harder but still possible, especially if it stuck to the river and up the rapids.

    If you get into sharks, the Greenland shark, we called them sleeper sharks, is known to be seen in the St Lawrence. Champ could have been a sleeper shark. They swim near the surface and reach over 20'. As do Bull sharks, although they are smaller.

    But I think Champ was most likely a plesiosaur. The coelacanth is a living fossil from the Cretaceous period that still lives. If it can last that long, I suspect other creatures could. The oceans are vast unexplored areas.

    As a SCUBA diver and avid snorkeler/skin diver, my Dad swam many a water. He never reported seeing anything other than known species, even during his Navy service. I picked up his love of water and am also a diver. I have played with giant Pacific octopus and seen eels, sharks, seals and sea turtles. But never Champ or any species that is unknown. I hope to one day see an unknown.

    Once again Jay, you perked my curiosity and have written a great article. Even though you did not mention Champ, you wrote about what Champ likely is. You also have made me pull up memories of home. It has been too long since I was there.

  2. As plesiosaur were air breathing aquatic reptiles one would think if they still existed there would be more sightings as they have to continually come up for air.

    I would love to see one of those things in the wild if they are somehow still around.

    1. True but the oceans are a vast area and it is always possible that these animals could simply bring their nostrils above the water to breath and would thus be able to breath without being seen.

    2. But that is pure speculation.

  3. Until recently there was no fossil record of the chimpanzee.

  4. It seems to me that when someone (reputable, at least) describes something with a fair level of clarity and detail, such as this, it indicates that that's exactly what he saw. Especially favorable is that he stated he's done several hundred dives and not seen one any other time. The ocean's a big world and still a mysterious one at that.

    1. Absolutely, I think this man is one of the most credible "sea serpent" witnesses. Scott Mardis actually got to talk to him and also thought that he was very credible.

  5. I believe plesiosaurs are still alive today. How could they not be with so much evidence supporting that they are alive?

    1. The lack of a type specimen fuels the doubt, although there have been a few carcasses which *could* have been plesiosaurian.

  7. Speaking of plesiosaurs, pinnipeds and sea serpents, do you think that some of the classical age depictions from Greece (especially the ones with forked tails, hair-like body protuberances , and long necks) that Dale claims to represent relict plesiosaurs could actually represent longn-necked pinnipeds?

    1. Although I try to not base things off of ancient depictions too much (as there could be cultural or mythological factors involved in the creation of these), I certainly consider it a possibility.

  8. Also, do you think that the "Naitaka" peteoglyph said by Costello and Mackal to possibly be of an actual sea serpent the artist saw could also be of a longnecked pinniped?

    BTW, Dale recently posted an article on FOZ.blogspot about this to clear up some misunderstandings. You should check it out.

    1. I agree with Dale's contention as to the Naitaka petroglyph in question, although there are a few carvings from British Columbia (such as the carving on an atlatl from the Skagit River) which I consider to be likely depictions of longnecks.

  9. So you're trying to say that the "Naitaka" petroglyph which Dale says is from Vancouver island is likely an attempt by the artist to reconstruct a longnecked pinniped?

  11. BTW, do you think that the unidentified carcass that Dale compared to the unidentified animal witnessed by the Alvin was also a plesiosaur-like pinniped along with the animal seen by the Alvin.

    1. It's possible, but I wouldn't place bets on it since witnesses seem to be horrible at accurately remembering features of carcasses especially after several years have passed. I have the book "Sea Serpent Carcasses—Scotland", and if I am not mistaken, it contains the details on this carcass (as it states that the information comes from a letter which was sent to Dale Drinnon). The fact that the man saw the carcass over 30 years before he wrote to Dale makes me think that the possibility of the man misremembering features is likely, but the details of the carcass are interesting nonetheless. The 12 to 14 foot long carcass was reportedly fresh and without decomposition with a four or five foot long neck, a short fur covering the body similar to that of seals, a head comparable in size to that of a horse, big eye sockets, teeth, four flippers, a mane that ran down the middle of the back, and a tail like that of a tadpole's with a fin that ran down it. To me, it's quite an interesting report and may possibly have been the carcass of a long-necked pinniped. However, it's important to keep in mind that descriptions of carcasses tend to not remain accurate as years pass and thus this may have been a misremembered carcass of a known animal.

    2. It also could have been a plesiosaur carcass with broken down tissue fibers accounting for the "fur" (the other features certainly sound plesiosaurian). However, a basking shark carcass would be the most likely candidate unless it truly was as fresh and intact as claimed.

  12. Sorry, I forgot to put a ? at the end of that sentence.

  13. Once again, about the Vancouver Island petroglyphs, I believe Dale was actually trying to tell us that one out of two of the actual petroglyphs mistaken for one petroglyph was a plesiosaur (but you would say a plesiosaur-like pinniped), the other actual peteoglyph being a boat.

  15. Although the lack of a fossil record was an argument which has kept me from being open to the plesiosaur hypothesis as of recently, Scott Mardis has done some work to point out that there are several examples of post-Cretaceous fossils which were identified as plesiosaurs at one point spanning from the Paleocene to Pleistocene (as stated in the update).

    ReplyDelete
  16. Just because there have not been finds reported, does not mean that they don't exist. The current status quo has created a scenario whereby anything discovered that contradicts the mainstream view does not see the light of day, as evidenced by the Smithsonian's bad habit of burying such finds, as well as the Vatican. This is unacceptable behavior, but it still occurs.

    ReplyDelete
  17. While I find the idea of deliberate hiding of evidence to suppress the truth very unlikely, there have been many cases of alleged post-Cretaceous plesiosaur fossils which were written off as "reworked".

  18. Here's another personal data point that is interesting given the date and location of the Alvin crew sighting. I'm a 65yo retired Navy Engineering Duty Officer and believe I saw one a mile off Boca Raton Florida inlet while fishing, about the same year. My sister was in the fighting chair, my father was driving, and upon hooking into something big, my father immediately began backing the boat down to get closer to the "fish." The gear was a 10-0 reel with 130-pound test line and a 15-foot steel leader wire to prevent the line from being cut by sharp teeth. Such a rig could handle about an 800# marlin. When I looked over the stern of the boat, I fell backward in fear of what I saw: a long necked creature with paddles for feet, a large body, and a scary head that I thought would attack us in the boat by merely coming over the transom with its long neck. My father asked me what was it, because it had just cut the line and gone, and after first telling him he wouldn't believe me, I did tell him. He shrugged. While I can't argue the merits of the fossil record issues pro or con, I still have a vivid memory of what I saw, and it still gives me a sense of awe of what is still not known about what's in the sea. I made contact in the 90's with a former submariner who was cataloging such sightings. Having been on sub duty for many years, he had seen and heard others report seeing many strange creatures.

  19. Hasn't the coelacanth also been "long gone" from the fossil record for 65 million years? No, wait... we found them alive less than a century ago. Hmm...
