Couldn't help myself, I just had to share this quote. ;D In a Philadelphia Inquirer article, Chester County developer mindful of conservation "Not much life exists in a cave," said Pete Goodman, president of the local chapter of Trout Unlimited.

Well, hate to be a damper on the party, but he's right, in a sense.
Compare species per square meter below and above ground, and above ground wins hands down. This is part of the reason biologists are fascinated with caves-- it is much easier to do a controlled experiment on a particular species, and know all the variables you are dealing with, especially with troglobites.
And trout don't thrive there...a number of show caves have so called 'blind trout' but these are merely time-depigmented normal trout, and unless fed trout food, they don't live long. (Trout do love to eat cavefish, by the way. I know of a couple of trout stocked springs where cavefish were unknown until the divers went into the dark passages, where the trout usually did not venture.)
Now, I didn't say what lives there isn't valuable-- it is. But population densities of nearly every living thing in a cave are much lower than on the surface.
