No need to check the dead dolphins gender, check for an evolving thumb. Might of hitch hiked further up the beach.
Maybe SeaSI can crack the case…I would check the P38 Mitogen-activated protein kinases (MAP kinases) that control cell responses to inflammation and growth signals. P38 MAP kinase, a member of this protein family, controls the production of growth factors and inflammatory cytokines, the molecules produced by the immune system that cause inflammation.
in an effort to get this discussion moved to industry talk…clark
Single tail, horizontal, two tips, plus several appendage fins, twin flippers. My guess is it doesn’t need any more. I’ve never seen an open ocean dolphin with a swimming, speed, or stability problem.
I don’t think I’ve seen any animal with two tails. Must be a reason.
OK… to tie this all into surfing now… you have all looked at why the dolphin doesnt have 2 tails, opposible thumbs, laser eyes, a propeller nose, and superman like charm… however, did anyone think that maybe simpler is better? this could also work for simple surfboard design… when was the last time someone made a 11’ longboard, 50/50 rails, flat bottom (no contour), with little rocker and a simple glass-on fin? maybe all the bells and whistles are just counter productive…
mis dos centavos…
edit: so… anyone with mad photoshop skills wanna make the dolphin with 2 tails, opposible thumbs, laser eyes, a propeller nose, and superman like charm?.. that would be an interesting pic… maybe a cool logo for a purist surfboard company. like the dolphin with the red circle with a strikethrough…
So why DID they design the P-38 with that wierd tail?
It was great diving from above, slow to manuever, slow in top speed, had great range, the fuel tanks split so you always can get by with one shot out, had a huge radar signature, was expensive to build and needed lots of runway to land and takeoff, who the heck decided it was any good anyways?
P-38 had lots of lift - don’t think it needed more runway than anyother aircraft. large for it’s day (though puny next to modern day fighter ) - could carry good ammount of ammo. It’s top speed in level flight was in excess of 400 kts - good climb rate - among fastest WWII aircraft - used as photorecon platform too. Range: it was a the aircraft chosen to intercept and ambush Admiral Yamamoto in a cargo aircraft off New Guinea – probably the fighter with most range until P-51 with droptanks came into service. Manuev: top scoring Gringo (Rich Bong) in WWII flew P-38s mostly against Japanese Zeros - slow (330 kts) but way maneuverable. Twin booms probably chosen for strong airframe to support the two large piston engines - more Hp, more speed, more ammo, more endurance. P-38 had no probs hangin in there – a WWII hardcharger.
Would inline dual fins, like 2 fins, one behind the other, (distance to be calculated as with size and dimensions), or parellel fins, say 1" apart side by side of equal foiling or flat foil on the inside, assist with direction or drive along the line???
That would be more of a twin fin dolphin question…
would they be conected at the bottom? if they wern’t wouldn’t they end up vibrating and creating lots of drag and turbulance if they were flat on the inside?
I just read in surfer that there’s 28 killer dolphins loose in the gulf, armed with toxic darts, bladed fins and other dangerous attachments, trained to attack guys in wetsuits…
Dude, thanks for that bee thing. That’s fuggin’ amazing. Man. I’m going to surf later today . . . just sweet. I love things that are cool like that.
Maybe the dolphin doesn’t need it. Maybe it is adequate enough for a dolphin? I read this book called Kon Tiki, and it’s cool. About a modern day Pacific crossing by balsa raft. Good book. Check it out. I remember there was a part where the crew would catch bonito (they call them dolphins) and how they mentioned it was hard to saw through them with a razor knife taking minutes. One of the antics they got to quell boredom was to feed sharks like San Diegans and Tourists hand feed fish to the dolphin / porpoise tank in Sea World. They’d (Kon Tiki crew)hold out a bonito and the shark would come out to bite it and they’d pull it up to avoid getting their hand crunched. They said the shark would saw through the bonito in a split second in a casual bite . . .
nature is very amazing . . . i notice it takes hella practice, instruments, crazy design etc all to get a fighter plane upon the deck of a carrier successfully. Check out pidgeons. They can fly at top speed, slow down and land a wire. So easy. I could write a book . . . but here’s something to think about. I thought it was pretty cool. I wish I could take credit for it but its not me.
Here’s a repost of it it has some stuff like my religion’s honor student beats your religion’s honor suicide bomber, the usual religious spiel. But this part got me thinking . . .

If you take a computer, a fighter plane, a robot, and a worm. Ask any scientist which one is the most complicated ?
They will say the worm is because its digestive system, the sensory system, the complexity of its cells. We still don’t know everything about the worm … even now we learn new things about them.
If the computer had a designer and a builder, if the figher plane has a designer and a builder, if the robot has a designer and a builder, and the worm is much more complicated that that? Then that means its Creator must be infinitely greater than the ones that made the computer, fighter plane, the robot . . .
If you think life on earth came around by chance . . . you’re wrong:
Take a cup filled with 20 dice, each numbered in order A, B, C, D on up, and if you wanted that be ordered A, B, C, D . . . that is 20 factorial. That number multiplied out is 10 to 347 th power. Anything 10 to the 50th is impossible according to a mathmetician. To get that order it would have to be the first role . …
That’s just ordering 20 things! 10 to 347 power. Your body has 200 bones, human DNA has 3 billion pieces ordered properly . . .
Ok imagine if each roll of the 20 dice takes a second, in 5 billion years is 10 to the 17 power seconds. To order 20 dice it takes 10 to the 347 … That means you wouldn’t have gotten first cell of life created by now if you left it to chance.
I keep seeing too many effin amazing things to belive that all of this (world, you, me, surfing) just happened by random chance.
ah hell someday i will find out i’ll just make a big carbon monofin, one with foot together pockets, and one with feet apart, I still think there would be more control apart, its like adding another dimension to it - the ability to explore control through twist, plus you can still do straight power drives by synchronizing. see how it does bodysurfing and on the mat.
so for all you smart asses yes the question should have been “Would a dolphin be more efficient, and offer heightened levels of control, and possibly speed, with twin tails driving its fluke, similar in visual appearance to the famed ww2 fighter the P-38 lightning?”
saying ‘there must be a reason’ to me they arent around is like 600 million years ago (or whatever the specific amount of years but you get the picture) “theres a reason we all live in the sea and dont have the ability to resipirate air” its just thinking about the past and the present but not thinking or imagining possible futures
still enjoyed everyones reply though, thanks for putting up with my ramblings
For years I had three things on my key ring. A CJ-5 ignition key, a Fins Unlimited fin box hex key (which doubled as a points adjustment key for the CJ), and a P-38.
Dolphins don’t need to evolve opposable thumbs. They are busy teaching the military their language right now and when we finally learn to understand them they will tell us how to run the world. How’s that?

YOU mean like a tuna? (see attachment)
Here’s what somebody asked recently over on Surfline.
Tuna has been around for 4 million years virtually unchanged.
It’s only real enemy in all that time has been tuna boats.
What other defense does that tasty treat have, in an ocean filled with swimming teeth, besides speed? Oh yeah it can change color. Scientists are working on paints that can do that too. But Tuna beat us to it.
Controlled turbulence in the right place is a good thing.
Which report would you prefer Harvard or NASA?
I’m surprised no one mentioned the propeller that already exists in nature…and has for millions and millions of years.
I Would Expect inline fins to go straight (drive) better than anything else you have ever used. If all you want to do is go straight then that’s great. The theory applied well to sailboarding. But like the albatross that’s extinct.
On evolution, I read this recently & it made me laugh…sorry mods, but this whole thread is marginal already

Subject: SOME DON'T NEED VACCINE
Recent news about the avian flu virus has raised concerns from main street to the White House. There is the possibility, even likelihood, that the virus will mutate into a form that can more easily infect humans.
As the president pointed out, a vaccine cannot be made until this evolution occurs. This raises the concern that it may be impossible to create enough vaccine fast enough to protect all our citizens. But there is hope.
Gallup polls tell us that up to 45 percent of Americans don’t believe in evolution. Since random mutation is the engine of evolution, these same people must believe that the virus cannot mutate. Therefore, there is no need to waste vaccine on folks who believe there is no possible threat to themselves – thus leaving a sufficient supply for the rest of us.
Perhaps the president, given his doubts about evolution, may wish to demonstrate his leadership by foregoing vaccination.
This approach has added benefits. Polls also tell us that disbelief in evolution is more pronounced among the less educated, the poor and conservatives. If the anti-evolutionists among these groups were to opt out of vaccination then, through immediate deaths and natural selection, we would reduce poverty, raise educational attainment, and become a more progressive society.
I met Thor Heyerdahl back in like 1965-6 or 7 at a University of Pennsylvania lecture on Kon-Tiki He brought and showed his “home” movies, which he made into a documentary. I was one of if not the youngest kid(s) in attendance. It is interesting how the theories of the early 50’s have changed.
The world did just fine for millennia without computers, fighter planes, and robotics. But if we were to kill off all worms, all life on earth would cease to exist.
But didn’t S. Hawking say something like (“) It is yet to be determined if intelligence is a survival skill.(”)
