I think it has it's steering wheel locked up, oh wait... there it goes.

Cool, I didn't know such a creature exists.

lol love the ufo conspircy music , more nature documentries should put ufo conspircy music over stuff makes everything sound dark and cool.

People talk about fish jumping out of the sea and sprouting legs as part of evolution. I think it'd make more sense to be something like this.

Where the F have you heard of people believing fish sprouted legs and thrust themselves out of the water ? Pro Tip: do not hang around those people.

Haha, I didn't mean it quite so literaly. But generally when I hear/read people giving generalised examples of evolutionary history, it often involves the fish leaving the sea at some point.

Thinking about it though, it depends if fish existed before mammals or not, as they definitely have a common ancestor.

/me goes check

Yeh, so the current understanding is that we have a common ancestor with fish, being a chordate, which can be both vertebrate and invertebrate. But that's a rather subjective take on when evolution left the sea.

It's not easy to find a phylogenic tree with a marker saying which species left water first.

/more checking

So what I meant by "fish jumping out of the sea and sprouting legs" were the tetrapods, which evolved from chordates leading to out of water compatible lungs; then fins to limbs etc.

However, they weren't the first creatures out of the sea. There were arthropods for starters (invertebrates, which also became insects).

My point was really that I can see this type of creature (an echinoid) evolving to be amphibious before either the arthropods or tetrapods; mostly because they would have a simpler path of evolution to be able to do so.

that is creationist's understand of evolution.

But some fish do sprout legs, and thrust themselves out of the water. They're even rather cute, see http://blog.nus.edu.sg/lsm1303student2011/2011/03/24/africanlungfish/

Heh, I could have kept my mouth shut

Seriously though, that's amazing. They also have a modified swim bladder, just like the early tetrapods.

Like a lot of things in evolution, for all the people that doubt x could evolve from y, there's usually not one example of a solution but many.

Not quite so relevant to this video, but the Coelacanth is almost exactly like the earliest tetrapods (and also rather cute). Some of the related fish have legs, or very leg-like fins, and walk on the bottom of the sea floor. The lungs of the lung fish are useful for both buoyancy and breathing... and the fish which can do these things perhaps has an advantage over the larger fiercer fish which can't.

Slowest... Roomba... Ever...

I believe they scour sand for food, so that's probably what's happening here. Which....would make it like a roomba...they are just specialized at sand instead of carpet and wood flooring.

I believe he is spinning donuts.

I wonder what time is like to this guy. How do sanddollars perceive the passage of time?

These sand dollars just propagate themselves without any respect for the gold standard!
