Friday Cephalopod: Toothy!

That has to be the most disturbing cephalopicture you've ever posted. Now I'm going to have nightmares.

Absolutely terrifying. There seems to be just enough room for it to bite off a toe...

Wow, so the beck structure has evolved to produce something akin to vertebrate teeth? Neat example of convergent evolution and I'm guessing this one has a taste for shellfish.

Is it real or photoshopped?

That has to be the coolest thing I have EVER seen. It´s a Lovecraftian reality.

I think I´m in love.

This photo is at the Tree of Life website and is attributed to Richard Young at the University of Hawaii.

Its so bizarre that I just sent him an email, hoping that he will verify that this is an unretouched photo.

It looks like it's singing.

Suddenly my fetishitic dream, of being fellated by a Dalek, seems somewhat less far fetched.

Hooray! It's Friday, and my, what big teeth it has!

I just discovered this BBC program: Walking with Monsters, Life before Dinosaurs.

Thanks for introducing a moment of pure weirdness into my otherwise ordinary working day...

I really love the cephalod beauties you usually display on a Friday, but that one is simply way cooool.

Is this a beak with thin dark stripes...?

I can just see this cheery thing swimming along the deep, making "chompchompchompchomp" sounds. It's Undersea Pacman!

When I saw the picture, I immediately started humming to myself, "Hello my baby, hello my honey, hello my ragtime gal!"

Y'golonac?

What is it with all the multi-appendaged cephalopods recently (i mean, more multi-appendaged than usual). I thought they were supposed to have 8, not 10! What are the two that don't have suckers for?

If that appeared anywhere other than here, I'd be certain it was a Photoshop job. Since it's here, I'm only pretty sure it's a Photoshop job.

Either way, brrrrrr. :-)

Its real, it showed up a while ago on Deep Sea News. Those are not actual teeth, they just appear as such.

Hmmm. Looks a lot like my uncle.

Oh crap, Daleks! Everbody back in the Tardis!.

Antecedent image.

So, the headless parasitic twin is upside down, fused at the spine...and developed teeth, along with the extra limbs...I get it...

Big brother.

Man... That thing's gonna give me nightmares. Then again, it looks like it's singing showtunes, so how scary can it be?

My #22 was posted here in error - too many tabs open. Sorry.

Though these pictures I've often enjoyed
That's a mouth that I'd rather avoid;
It brings the maligned
V. Dentata to mind
(Look it up--it's right there, under "Freud").

Oh, crap. I'm not a big octopus fan, but most of them at least don't creep me out. However, I saw this photo the other day, can't remember where, and I have to say that I absolutely HATE this particular Octopus.

It's so freaky looking with those human-like teeth. And I wasn't entirely sure if it was a spoof.

Now I'm even more creeped out. Thanks.

demallien, you're thinking of Octopi. Octopi have 8 apendages. Sqauids can have ten to twelve apendages. Nautilus can have quite a bit more, but I'm not even going to guess at that one. Anyway, hope that answers your comment, and if I'm in anyway mistaken on any of this please call me on it, I'm certainly no expert on the subject. I just think cephlapods are cool

Padma Lakshmi loves cephalopods.

That ain't nuthin'...you want Photoshopped "animals," check out:

(Great for throwing students off in evolution classes!)

Just perfect for a LeFort 1 osteotemy of the lower mandible to correct his craniofacial dysmorphism.

Is it just me or does this remind anyone of "Clutch Cargo" ?

(I know someone's going to come up with a great vagina dentata joke.)

Any animators out there? A cephalopod version of the "Rocky Horror Picture Show" introduction could be kinda cool...

Opps, sorry Cuttlefish, I missed your post. Brilliant as ever.

Reminnds me of something from a David Cronenberg movie.

I expect it to start talking and sounding like Burroughs.

I...need...a...hug [weeps openly]

Surely this is the unholy union between a memeber of the Osmonds family and a Octopus....you crazy scientists! Stop now before its too late!

Oh. That was very good.

Goatboy #8 - that was the best laugh I had all day.

Unfortunately, according to the TOL website, this is the only known specimen and it's just 25 mm long so unless they grow bigger you're in for some disappointment.

Feed me, Seymour PZ!

Friday Cephalopod: Toothy!

Also toothsome. Mmmmm.

Todd#38

Well, until science catches up with my Fantastic Voyage fantasies anyway.

Mmmm, Me, Raquel Welch, a Promachoteuthis sulcus, some white blood cells and Donald Pleasance.

There's an orgy to tell your grandkids about.

Here is an awesome glass Octopus, for the art lovers amongst you. Much Prettier without those horrible teeths.

We discussed this a fair bit over on TONMO... Steve O'Shea got in a final word that it's an unusual buccal mass musculature, which was my suspicion since the TOLweb didn't mention anything weird about the mouth in the species description. See http://www.tonmo.com/forums/showthread.php?t=8276 for the whole thread.

And Michael, you're correct that squids (and cuttlefish) like this one have ten appendages (8 arms and 2 tentacles) but they never have twelve. There are a few species of squids that lose the tentacles at adulthood so they start with ten and go to 8. Nautilus does have a lot more, 40 I believe. For completeness, Vampyroteuthis infernalis has 8 arms and two "filaments" and extinct belemnites were squid-like and had 10 hooked arms. The paper PZ posted a few months ago about nautilus development suggested that nautilus arms are produced from 5 pairs of buds, so there's a lot of evidence that the 10 appendages is an ancestral trait and that octopus just lost one pair somewhere along the line. Interestingly, the pair modified to filaments in Vampyroteuthis are not the same ones modified to tentacles in the squid.

damn, Todd (#38) beat me to it, but still, these facts bear repeating:
1. This picture is of the only--single--specimen of this species ever seen
2. It's only one inch long.

And now, another attempt at the joke only I seem to appreciate:
Vagina radula

Someone always beats me to the punch; I was going to make the Little Shop of Horrors reference!

That really creeped me out. At least until I read the "hello, my baby" comnment and the cuttlefish poem. One more nightmare defused.

So nice to have the real Pharyngula back. Perhaps all of the trolls were scared off by the guard cephalopod. I would hate to have that thing grinning at me from a dark corner.

Yikes! I'm still having a difficult time believing this photo is genuine.

Creepy Friday jitters now, thanks.

#41: Sure, just leave out the Donald Pleasance part unless you want to give them nightmares.

Hmm. I think I might have dated her.

It looks to me like the beak was just removed, but I checked the species description and there's nothing there about the beak of P. sulcus, so I have no idea what's going on. I actually was a reviewer for this paper and didn't notice the weirdness of that picture the first time around...

Someone mentioned they'd e-mailed Dick Young...what did he say?

Wow! A Cuttlefish limerick (with a v. dentata reference, no less!) and a Padma Lakshmi sighting!

Best.Thread.Evar!

Well, maybe that's stretching a point... but it is a refreshing change from the sniping and sockpuppetry going on in other threads recently. Y'all have a good weekend, y'hear?

PZ,

That is, like, so two weeks ago; if you want to be current, then check this out:

http://www.plantationhomeaccessories.com/fi-octreds.html

It looks like there's a human trapped inside its body. What a horror. This shall be my new wallpaper.

Heh - I had a sequence of images zip through my mind when I first saw this.

1) Judy Garland singing "Over the Rainbow"

2) Feed me, Seymour!

3) Space Angels (Clutch Cargo in space. Not that you youngsters will remember either)

4) what a PERFECT sidekick for Rippy the Gator! (Arrogant Worms tune)

5) MOM!

You guys are freaking out over the vagina dentata, aren't you?

If it had a bit of bling on the tentacles it'd look just like Liberace.

If ever a picture needed to be lolcatted, that's it.

Can't sleep! Squid'll eat me! Can't sleep! Squid'll eat me!

It's a langolier with tentacles!

I am absolutely, totally, completely positive that thing is singing "Some Enchanted Evening" from South Pacific. Go on, scroll back up, have a look, tell me I'm imaging it!

Sorry - that should be "imagining it". I blame the 3 chardonnays for the typo but that could also explain my South Pacific theory.

The photographer who took this photo, Richard Young (a biologist at the University of Hawaii), has just graciously answered my query to him about it:

"The photo has not been altered. The interpretation of what it shows has been incorrect. The squid doesn't have teeth. The structure that looks like teeth is a circular, wrinkled lip that surrounds the beaks. Only the top and bottom the the lips are visible in the photo and the beaks are underexposed (they are black) and don't show in the photo."

Whatever the case, it still looks like the love child of Abraham Lincoln and a cephalopod.

So the thing that we see is a sheath,
With the beaks tucked away underneath;
Not as strange as before
(And I think, what is more,
That lips are much nicer than teeth).

You guys are freaking out over the vagina dentata, aren't you?

Hey, did I try the vagina radula thing yet?
I did?
sorry...carry on...

More recent version of the page mentioned in #19.

The lolcats site has belatedly caught on to this picture now - except they're saying they don't know its source. Is it worth someone telling them?

Is this a beak with thin dark stripes...?
