An Ancient Fish Is Running Out of Time

By Chris Hunter, The New York Times

04 September 15

 

ROM an evolutionary perspective, the pallid sturgeon is a thing of beauty.

Its eyes are a bit beady, it’s true, but good vision is not a prerequisite for living on the bottom of the Missouri River. And its toothless mouth, with its protruding, whiskerlike barbels, is creepy. But these barbels are perfect for sensing food, which it sucks in like a vacuum cleaner.

No, these fish are not sleek and beautiful like trout. But this species of sturgeon, which can grow to a length of six feet and weigh as much as 80 pounds, has managed to survive since the time of the dinosaurs, with fossils dating back some 70 million years.

A note of caution regarding our comment sections:

For months a stream of media reports have warned of coordinated propaganda efforts targeting political websites based in the U.S., particularly in the run-up to the 2016 presidential election.

We too were alarmed at the patterns we were, and still are, seeing. It is clear that the provocateurs are far more savvy, disciplined, and purposeful than anything we have ever experienced before.

It is also clear that we still have elements of the same activity in our article discussion forums at this time.

We have hosted and encouraged reader expression since the turn of the century. The comments of our readers are the most vibrant, best-used interactive feature at Reader Supported News. Accordingly, we are strongly resistant to interrupting those services.

It is, however, important to note that in all likelihood hardened operatives are attempting to shape the dialog our community seeks to engage in.

Adapt and overcome.

Nobody cares, just as they don't care about reptiles and amphibians. Fish live in a foreign medium. Herps have cause repulsion but are also rather hidden, for the most part. All are the canaries in the coal mine, as is said.

Every specie has its place and contributes to all other life cycles.

The Corps of Engineers has been the cause of numerous disasters, environmentally and at some point all of us are going to have to scream out against them.

Right on!
This now also includes the huge, ancient Columbia River White Sturgeon, which is not only suffering from the dams built to pacify the River and send power to California but also warmer early summer temperatures; http://www.tri-cityherald.com/news/local/article32233083.html.
Wonder how the prized Beluga of Iran, Georgia, Black Sea are doing?

California wants electric cars now...to the detriment of state as far away as Colorado!

The list is long, and the dams are endlessly proposed. River pollution and change has caused more issues than is recognized.

Even in Belize there are river issues. One cannot view manatee when the tide is going out due to the pollution flowing to the ocean. Hard to say how long river dolphin will last.

More evidence, if any were needed, that there are just too many of us human critters.
