Its an alien world in every river - out-of-doors


When you look at a river, what do you see? A few flies on top? A fish or two?

Look closer.

Lay down on your chest at the side of the river and stare down into it. Look at a rock or a stick. Not very interesting? Keep looking.

Soon, you begin to become aware of equipment that don't seem to belong. Brushwood don't come with barely tubes of sand attached. What's that black bump? Oh, it's moving. It's. . . grazing? Every cascade holds a tiny alien world, packed with creatures disparate whatever thing we see on land.

Clinging mayfly and stonefly nymphs graze like tiny cattle on the algae and minute animals that cover every twig and rock. Sinister damselfly nymphs hunt them with a creepy, cautious irritation attitude reminiscent of both a marauding cheetah and killer robots from the hope in some cheap sci-fi flick.

Caddisfly larvae build complicated houses of tiny gravel and debris, which the tiny carpenters drag about with them like a shell. Colonies of them bring together on a choice of twigs and rocks, barely housing subdivisions in a tiny marine town.

Swimming mayfly nymphs, some of them shaped much like the slimy bad character in the Alien movies, dart from place to place with the neatness of diminutive minnows and take up base to catch food migrant by in the current. And below the ground, burrowing mayfly nymphs dig lairs with their able tusks from which they emerge only at night to prowl for food. All hope to avoid the cavernous jaws of a big, ugly, marauding dragonfly nymph.

Until now, it was hard to comment this marine world devoid of in receipt of very cold and very wet. But a new website, Troutnut. com, has brought full photographs and videos of this absorbing world and its residents to the comfort of your central processing unit desk.

The website was sparked by the sport of fly fishing, in which trout anglers craft realistic imitations of tiny course creatures from an daunting mess of fur and feathers, and award their imitations delicately, even artistically. For them, develop cinema of the real thing mean change for the better imitations and more trout. But Troutnut. com's quest for more and larger trout has led to a foretaste at this alien world that everybody can enjoy.

So next time you're on foot past a stream, stop to take a nearer look. Or head over right now to http://www. troutnut. com. Both way, you'll be amazed.
