Shark swimming in a wave: Is this photoshopped?

[PonoBill]

Seriously, you can't tell squat from a single shot. All it takes is for the body to be arched, the tail deeper in the wave, or twisted a bit for the "shark" to be a dolphin, or vice versa. Glancing at it, from the way the body mass seems distributed, I'd say shark vs. dolphin, but it's just an impression. People want to see what they want to see.

This is not a pipe.

Yes, but maybe an ill temoered dolphin?

Thats Hilarious.  Remember this movie??

[stoneaxe]

I'd say dolphin also. Besides the other indicators already mentioned the pectoral fin placement is too far forward for a shark. Not much to go by, like Bill said a twist here a bend there and the view changes.

Not to mention how the curve of the face of the wave can distort the shape of whatever is there.
Bent water can play tricks on the optics.
Sticking my neck out,,,,,,, I say it's one or the other, and it's alive!!!

That rocky bottom could be a salt water croc for all I know.  Steven Stills wrote about paranoia

Hey....I can see the virgin Mary in that wave pic....

Did he say anything bad about me in what he wrote?

Pfffft!  I can see Jesus! 

[Weasels wake]

Right there!

Dolphin, front fins are further forward and the fluke is horizontal.

Yes and all of the proners everywhere are out to get you.  Watching your house, tapping your phone, reading your mail.  Bwaa Ha Ha Ha   (JK)

The NSA wants us to think it is a dolphin or a shark but I am pretty sure it is an aquatic drone or UUV (Unmanned Underwater Vehicle).  DARPA has been doing R&D on some of the key technologies needed to make these a reality since at least the early 1990's. 

The evolutionary part was reducing the size the the RTG (Radioisotope Thermoelectric Generator) power source that gives these aquatic drones an endurance and range that is hard to fathom.  RTGs have been powering certain satellites since the early 1960's.   

The truly revolutionary part was the eventual development of high bandwidth hydrocoptic marzel vanes that could be put in bio-realistic fairings and made to look and act like pectoral and dorsal fins.  The stability and control requirements for an ISR vehicle of this type are quite extreme so clearly the old industry standard of servo controlled fins was not going to allow them to take full advantage of the enormously high resolution cameras that they carry. 

They can read the length, width and thickness of your board written on the 1/8" stringer from over 500 ft away in clear water.  They can deduce your religion by performing biometric analysis of the bulge in your wetsuit.  They carry highly sensitive acoustic instruments and since sound carries so well in water they can hear your conversations even while you are on the beach.

These days with drones both in the air and in the water watching us surf, is there any place that we are safe from the NSA?  The next thing you know they will find a way to place a high resolution video camera and a highly sensitive microphone on each and every one of us so that they can monitor our activities in the bedroom or the barnyard (depending on if your definition of the term "animal husbandry" leans to the liberal side of the textbook definition).  After that they may try fluoridation of our water supplies to pollute our precious bodily fluids.  Where will they ever draw the line?

Oooh. That was fun. Actually, for my senior year in high school my science project was an underwater drone, which I called an Independent Underwater Telemetric Robot. I'm pretty sure my brother remembers it vividly if inaccurately--he was fairly little. Version one was lost at sea, version two I couldn't get the peripheral seal to work. That might be version one in that wave, spying independently. I built it in 1965. It's been out there for 49 years, evolving, scheming, growing. It could be anywhere. And where does all that goPro footage go anyway? Don't worry about NSA, they're more or less on our side. Worry about IUTR and it's little brother, SkyNet.

[Beasho]

. . . Worry about IUTR and it's little brother, SkyNet.

What is IUTR?  Nothing came up on a quick Google search.  Speaking of which Google is starting to manifest itself to be Skynet (not that I am anti-Google) but the likeness is developing.
