Giant Ocean Platypus of Alaska?

Posted by: Loren Coleman on June 25th, 2008


In Karl Shuker’s book, Extraordinary Animals Revisited, there is a subsection entitled “The Cryptic Case of the Colorado Platypus.” In actuality, the largest part of those two pages are devoted to a story of a supposed sighting of a platypus off the coast of Alaska.

Unfortunately, the investigation of the case is distracted by how the initial eyewitness labeled and linked what he saw with an exotic known animal’s name. People associate “seen cryptids” with the animal world they know or have seen on television. But, of course, platypuses are Australian, freshwater, and usually no bigger than 20 inches long, not Alaskan, marine, and six feet in length.

Nevertheless, this story has ended up in the “platypus file,” after it first was shared on the Bigfoot email list (on August 7, 1999). It then was posted on Chad Arment’s cryptozoology elist, and finally found its way into Karl Shuker’s chronicling of the encounter. My headline comes out of the overall question of it being called a “platypus,” not by the chroniclers but by the eyewitness. (Things like this happen in investigative skeptical cryptozoology. Items get a tag on them and gather dust in a file cabinet. We brush them off, once in awhile, and make inquiries about them again. New angles develop and new insights are seen.)

Therefore, below is the essence of how Rob Alley recorded the sighting first on that Bigfoot list:

Several years ago Mike F., a successful Ketchikan businessman, contractor and retired fisherman asked me…whether I had ever studied or read anything about platypuses in North America, specifically whether I knew of any prehistoric giant forms….

[Later he told me] that as a young man forty or so years ago he had stood on shore near Mountain Point south of Ketchikan and spent a minute watching an animal in the water at very close range that simply resembled a giant platypus. He described the creature as dark with a bill and feet like a platypus only the overall size was six feet or possibly greater. He gave no mention of the tail if there was one. The sighting was in shallow water on a rocky shoreline and the creature was close to the surface….

The man is an experienced commercial fisherman and stated categorically that it was not a known species of seal.

Ocean temp here doesn’t vary much from 50 degrees.


The investigator who interviewed the eyewitness is J. Robert Alley, the author of the 2003 book, Raincoast Sasquatch: The Bigfoot / Sasquatch Records of Southeast Alaska, Coastal British Columbia & Northwest Washington from Puget Sound to Yakutat. It is logical that Alley would be told such a story, considering the fact he is a lightning rod for cryptid sightings in Alaska.

(Ignore that the account is repeated at the end of Shuker’s subsection in summary, as if what is there is a different sighting. Overlook that a small mention of an alleged Colorado platypus incident leads off a paragraph and merges into the Alaskan case. And don’t pay attention to Shuker’s question about “where, precisely” did the “Mike F.” sighting occur, even though the account clearly says where it happened. Shuker told me recently those are just clerical, editing errors.)

The story contains the location of the Alaskan origins of this sighting. The city of Ketchikan is noted, and that’s a coastal location in Alaska, on a marine inlet that opens to the Gulf of Alaska. The specific location noted for the sighting, Mountain Point, is 6 miles south of Ketchikan, Alaska, and is today a well-known clear water snorkeling area off Alaska. This is an ocean sighting.

Could this cryptid be a turned around, misidentified pinniped, perhaps a sea-elephant, which makes more sense than a platypus? Perhaps it is something simpler?

No, says the eyewitness, “categorically…it was not a known species of seal.”

Does anyone have any experience with an animal off the coast of Alaska that could have been confused with a “six foot long platypus”?

Cryptozoology artist RobRoy Menzies of Alaska emails me this: “I would guess somebody saw a sea lion with a halibut in its mouth. I have experienced catching halibut only to watch sea lions tear it up and swim off with it!”

San Cruz remains of a Baird’s Beaked Whale.


A bizarre footnote to this story is that the Latin name for the Alaskan blue king crab is Paralithodes platypus.

    As goofy as this might sound; my guess would be that the witness saw an immature walrus. Check out this photo and try to imagine it lolling about in dark water a little ofshore:

    juv walrus

    Seriously, the guy saw it for about a minute and it must have been at least partially submerged.
    Ketchikan is not within the range of the walrus, and it would not be implausible that a juvenile got caught in a current and ended up south of its normal range. This happens more than you might suspect! For example, we rescued several juvenile hooded seals off the east coast of Florida while I worked at Sea World-and the natural range for hooded seals is from around Svalbard in the east to the Gulf of St. Lawrence in the west.
    A llloooonnnggg way from Florida.
    I’m just sayin’.

  2. dmpelley responds:

    I think I forgot to mention the neato platypus models! Thanks for putting those up, Loren!

  3. Kainan responds:

    Could the broad muzzle of a young Steller’s Sea Cow be perceived as the bill of a platypus? … or an OOP dugong?

  4. fmurphy1970 responds:

    Could it not have been a large sea otter? They can grow to six feet or more and their legs and feet are kind of similar to a platypus. I can’t think of any other marine mammals that are covered in fur, that would fit the bill(sic!)

  5. shumway10973 responds:

    A 6 foot platypus… Don’t you think someone would have caught a glimpse of one before this? True, we haven’t caught big foot, but we have had sightings (note plural…more than one). Has someone asked the really old fishermen about this one? Maybe any Eskimos living near by? Those 2 groups should know that area of water better than anyone else. We just need either a legend/myth or at least a couple more eyewitnesses to get a better idea of what he saw.

  6. MattBille responds:

    We are left here, I think, with the question of the bill. If the witness correctly identified a bill, then we have a brand new cryptid on our hands. If he might have been mistaken about the bill, we can write it off as any of several known marine mammals. I don’t think we will ever make any progress on this one – unless, of course, another giant platypus shows up.

  7. red_pill_junkie responds:

    I remember an old b&w photo of the mysterious carcass of an animal that had been washed off to the beach, and you could see in the photo what looked like the beack of a duck, or a platypus.

    That photo is used in many cryptozoologica books, does anyone else remember it?

  8. gavinf responds:

    I like the idea of a six foot long marine platypus. Unless it has the poison spurs of the original. That would be scary!

    Is this it?

    This creature was believed to be the remains of Baird’s Beaked Whale.

  10. Blue Mako responds:

    red_pill_junkie, you might be thinking of the photo of what ,iirc, was a beaked whale carcass…

  11. cryptidsrus responds:

    Cool, a 6-foot duck-billed platypus…

    Unusual, to say the least. IF it exists.

    Now I’ve heard of everything.

  12. red_pill_junkie responds:

    David Fullam: Nail it! 😉

  13. red_pill_junkie responds:

    PS: And i don’t see the resemblance with the beak of Baird’s whale. I think that, and the animal described by the witness in the article, might be a new species of beaked whale.

  14. DavidFullam responds:

    Glad to help out.

  15. joppa responds:

    I think sea otter holding a flat rock for smashing shellfish. Now if we can just explain that marsupial Bigfoot…

  16. springheeledjack responds:

    I am wondering about some sort of walrus or seal with something in its mouth, much like Joppa…if he only saw it for a minute or so, he could have possibly seen a large flat object at the front and made a connection with it having a bill.

    The only reason…well not the only reason, is all of the above mentioned…the platypus does not really grow that big, as far as I know it has never had a habitat outside of Australia (except maybe in a zoo), and well, no offense, but a giant platypus smacks of a Sci-Fi original movie on Saturday night!

  17. bigdog82644 responds:

    I have watched sea otters swim with clams and seashells in their mouths like a dog fetching something. It could look like a platapus.

  18. Tengu responds:

    I immediately thought ‘beaked whale’ but I don’t know nuffin.

  19. youcantryreachingme responds:

    Do beavers visit the sea?

  20. Dj Plasmic Nebula responds:

    sci fi channel hahahahahahhaah

    as for the b and w pic.. i don’t think it’ has nothing to do with any beaked whale..

    i think if it’s still alive, it was a living fossil or at least a cryptid.

    but none the less it was the best photo (in my opinion) of a unknown animal.. there’s another one but i can’t find it yet. 🙂 i remember seeing it. 🙂
