A rare coelacanth was recently caught - which scientist not long ago believed them to have gone extinct with the dinosaurs.
This is not the first time though, scientist were really shocked in 1938 the first time a coelacanth turned up off of Africa's coast.
Since then the fish has become a fasination for many and has sparked a debate about how this fish which has limb like fins fits into the evolution of land animals.
The most amazing feature of this prehistoric fish is it's lobe fins, which extend away from its body like legs and move in an alternating pattern much like a trotting horse.
Other unique characteristics include a hinged joint in the skull which allows the fish to widen its mouth for large prey; an oil-filled tube, called a notochord, which serves as a backbone; thick scales common only to extinct fish, and an electrosensory rostral organ in its snout likely used to detect prey. X
Their population numbers now are unknown, and have are on the endangered list and are refered to as a living fossil.
arrow Could the coelacanth fish be one of our closest ansestors among the marine life?
arrow Does the discovery of a fish that "walks" confirm an evolutionary relationship between coelacanth and land vertabrates?
arrow What do you think about finding such a prehistoric fish?
What are the chance's of finding a prehistoric land animal?
arrow Does this make you wonder about exactly how much we know about our planet and it's inhabitants? How much do you think we know?

I think it's crazy though, I mean I'm not a fisherman or know much about fishing, but this prehistoric fish is subject to deep ocean waters - How is it that a fish that lives deep is caught? Do we actually fish 600+ feet or so deep?
...
Maybe the fish is wandering off to land....getting ready to walk.

I've often fantasized about how much life is in the sea that we are completely ignorant to. The chances of finding something like this are so extreme that when it happens, you can't help but wonder how many more are out there.

I know, it's really amazing.
We dont' really know all that much, especially deep ocean life.
Perhaps it wouldn't be so common to find prehistoric life on land, although I rember vaugly hearing something about an Island that contained a bunch of unknown animals?

Actually I am pretty sure there is more money put into space exploration than there is to marine exploration. Which is sad since more of our earth is covered in water than land...

Fish dont always stay at deep depts even if they live there. Here is a video of another prehistoric fish that usually lives in the deep ocean. Prehistoric SharkHere is another interesting video where another evolution idea can be thrown in, because it seem that the coelacanth actually gives live birth instead of laying eggs like most fish. Video of Coelacanth

I heard about the first Coelacanth find quite some time back, I thought it was amazing and wished I had been the one to find it (last name's Fisher soI had to imagine the irony of the news). I actually don't find it too awefully strange in some ways, since when you get right down to it, many species of arthropods, reptiles, moluscs, and fish haven't really changed that much, if at all, for millions of years, scorpions in point of fact existed in the oceans long before the coelacanth and they basically were only larger versions of ones we know of today, Crocodiles have hardly changed since the times of Dinosaurs, same with sharks. You get right down to it, there are numerous "living fossils" on our world, they merely lost weight, so to speak.

Agreed.
What of this debate of weather or not this fish is the proff of evolution?
You think this wipes out intelligent design?

You think this wipes out intelligent design?Oh please don't insult me with that bull, Intellegent Design, bah. That's just christianities way of adapting to the times, like it's done before. It sees something that has the greater populations' attention and tries to come up with Their equivilent. It's the only reason christianity has managed to survive this long. As to how the Coelacanth is proof of evolution, just look to it's bodies design, the pectoral and rear fins are elongated and have more muscularture to it, clearly this fish was a step in the process for land based verdibrates. Watch Discovery channel for, I think it's called, Walking with prehistoric animals, it covers from first arthropods and begining verdibrate animals, up to the dinosaurs, you'll see where the coelacanth fits in to the evolution of land based verdibrates. And just a minor note, I'm atheist.

I'm not insulting you, and I don't care what religion you are.
I was simply asking you or anyone's thoughts on the debate that's going on right now about weather or not this is absolute proof that evolution is real and shuts up the people who believe in inteligent design over evolution....I mean what else can they say now question

I know, I just wanted to state my psoition on the intellegent design thing. I think finding the coelacanth is clear enough proof of evolution

There could be possible living marine dinosaurs in the deep ocean depths. In fact, we have barely even explored the ocean. There could easily be even huger monsters, like a living Megaladon!
rolleyes This sounds crazy, but it may be true.

I agree!
I can't wait till we find something crazy like that.

there are probably many "Extinct" fish still living deeper in the oceans to get away from humans
