Disgusting, Scary 'Walking' Fish Invades Maryland
texchanchan writes: "It's from China, it's a predator, and it can live for DAYS out of water. And it's in Maryland as reported at Yahoo. 'They can survive for two to three days out of water, breathing air with a primitive lung, pushing themselves around with their pectoral fins.' Read about it at the Maryland Fishing Report site or just look at its picture. Maryland Fishing Report says: 'This fish was most likely introduced by an individual with an aquarium. Never release aquarium fish into ponds and lakes!' Those exotic species will get us yet."
From the article: But it is not quite true that they can walk on land, Schwaab said: "We would sort of characterize their mode of transport more along the lines of wallowing." .The national geographic has more info about similar alien species besides a better report on the same fish.Also, Check out the alien picture gallery, for photos of similar species.
Re, could this be living proof of the evolutionary path that aquatic creatures took to make it to land...?
...many millions (billions) of years ago...
It's live wiggling proof that intermediate forms exist. An argument sometimes used against Darwinian evolution is that something in between species A and B couldn't compete with the fully functional A creatures now in their prime, nor would it yet have the equipment needed to be a successful B. But this guy looks like he's succeeding quite well as A fish that's Becoming amphibious (given a few tens of millions of years). If that's possible now, why not in the past as well?
Re,
Geologic time on a short page
Geologic time on a long page
Links to a lot of geological time charts
This site Precambrian Earth is a red hot mix of geology (from a lot longer ago than our amphibious ancestors) and what might be religion.
IT has been asked by the opponents of such views as I hold, how, for instance, could a land carnivorous animal have been converted into one with aquatic habits; for how could the animal in its transitional state have subsisted? It would be easy to show that there now exist carnivorous animals presenting close intermediate grades from strictly terrestrial to aquatic habits; and as each exists by a struggle for life, it is clear that each must be well adapted to its place in nature. Look at the Mustela vision of North America, which has webbed feet, and which resembles an otter in its fur, short legs, and form of tail. During the summer this animal dives for and preys on fish, but during the long winter it leaves the frozen waters, and preys, like other pole-cats, on mice and land animals. If a different case had been taken, and it had been asked how an insectivorous quadruped could possibly have been converted into a flying bat, the question would have been far more difficult to answer. Yet I think such difficulties have little weight.
Here, as on other occasions, I lie under a heavy disadvantage, for, out of the many striking cases which I have collected, I can only give one or two instances of transitional habits and structures in allied species; and of diversified habits, either constant or occasional, in the same species. And it seems to me that nothing less than a long list of such cases is sufficient to lessen the difficulty in any particular case like that of the bat.
