A New Species of Leech Is Discovered Near Washington, D.C. (smithsonianmag.com) 80

Posted by BeauHD from the lost-and-found dept.
schwit1 shares a report from Smithsonian: In the summer of 2015, when Smithsonian research zoologist Anna Phillips and other scientists were standing in slow-moving swamp water, letting leeches latch onto their bare legs or gathering them up in nets from muddy pond bottoms, they didn't realize that some of the bloodsuckers they'd collected belonged to an entirely new species. But in a just-published paper in the Journal of Parasitology, Phillips and her colleagues from the Universidad Nacional Autonoma de Mexico and the Royal Ontario Museum report that a previously unknown leech species, Macrobdella mimicus, is the first to be discovered on the continent in more than 40 years.

Parasitologists typically rely on the arrangement of pores on the bottom of leeches' bodies to help distinguish species. With a close inspection, the researchers noticed a subtle difference in the spacing of the leeches' accessory pores. (While leeches are hermaphrodites, they mate with other leeches, and accessory pores secrete mucus that allows the mating leeches to stick together.) M. decora had four accessory pores grouped in two rows of two, just like the outlier group, but the new species had a set of pores located several millimeters farther back on their body. The similar pore pattern, however, led Phillips and the other scientists to name the new species Macrobdella mimicus, after the Greek word for "imitator" or "actor." The new species is olive-green with orange spots, about as long as a cigarette and as wide as two. It has three jaws, each containing 56 to 59 teeth (fewer than M. decora), which it can use to bite and siphon blood from humans. Leeches like this species can suck two to five times their body weight in blood thanks to expandable pockets in their intestines, explains Phillips.

      It turned out that the swamp was far more powerful than anyone thought, and the office of the presidency still isn't enough to root them out. The extent to which the unelected government takes actions that are not in the interest of the public has been astonishing in its enormity. They run the country, not the president, not the courts, and certainly not Congress.

        In fairness, the office of the presidency isn't even trying to root them out.

That's one of the first orders of business for a president: Remove all the corrupt, politically-driven scum that their predecessor put in, and replace them with corrupt, politically-driven scum that owe their loyalty to the new president and his party. Draining the swamp is just the preparation to fill it again with a slightly different swamp.

        Part of Washington was built on a drained swamp. There were no environmentalists in those days. Too bad too, because when the sea levels rise another foot, Washington too will be swamped again by the Potomac. It even has tides. See Miami for how well that's working out for them.

        Joe gets up at 6 a.m. and fills his coffeepot with water to prepare his morning coffee. The water is clean and good because some tree-hugging liberal fought for minimum water-quality standards. With his first swallow of water, he takes his daily medication. His medications are safe to take because some stupid commie liberal fought to ensure their safety and that they work as advertised.

        All but $10 of his medications are paid for by his employer's medical plan because some liberal union workers fought their employers for paid medical insurance -- now Joe gets it, too.

        He prepares his morning breakfast: bacon and eggs. Joe's bacon is safe to eat because some girly-man liberal fought for laws to regulate the meat packing industry.

        In the morning shower, Joe reaches for his shampoo. His bottle is properly labeled with each ingredient and its amount in the total contents because some liberal crybaby fought for his right to know what he was putting on his body and how much it contained.

        Joe dresses, walks outside and takes a deep breath. The air he breathes is clean because some environmentalist wacko liberal fought for the laws to stop industries from polluting our air.

        He walks on the government-provided sidewalk to the subway station for his government-subsidized ride to work. It saves him considerable money in parking and transportation fees because some fancy-pants liberal fought for affordable public transportation, which gives everyone the opportunity to be a contributor.

        Joe begins his work day. He has a good job with excellent pay, medical benefits, retirement, paid holidays and vacation because some lazy liberal union members fought and died for these working standards. Joe's employer pays these standards because Joe's employer doesn't want his employees to call the union.

        If Joe is hurt on the job or becomes unemployed, he'll get a worker compensation or unemployment checks because some stupid liberal didn't think he should lose his home because of his temporary misfortune.

        It is noontime and Joe needs to make a bank deposit so he can pay some bills. Joe's deposit is federally insured by the FSLIC because some godless liberal wanted to protect Joe's money from unscrupulous bankers who ruined the banking system before the Great Depression.

        Joe has to pay his Fannie Mae-underwritten mortgage and his below-market federal student loan because some elitist liberal decided that Joe and the government would be better off if he was educated and earned more money over his lifetime. Joe also forgets that in addition to his federally subsidized student loans, he attended a state funded university.

        Joe is home from work. He plans to visit his father this evening at his farm home in the country. He gets in his car for the drive. His car is among the safest in the world because some America-hating liberal fought for car safety standards to go along with the taxpayer funded roads.

        He arrives at his boyhood home. His was the third generation to live in the house financed by Farmers' Home Administration because bankers didn't want to make rural loans.

        The house didn't have electricity until some big-government liberal stuck his nose where it didn't belong and demanded rural electrification.

        He is happy to see his father, who is now retired. His father lives on Social Security and a union pension because some wine-drinking, cheese-eating liberal made sure he could take care of himself so Joe wouldn't have to.

        Joe gets back in his car for the ride home, and turns on a radio talk show. The radio host keeps saying that liberals are bad and conservatives are good. He doesn't mention that the beloved conservatives have fought against every protection and benefit Joe enjoys throughout his day. Joe agrees: "We don't need those big-government liberals ruining our lives! After all, I'm a self-made man who believes everyone should take care of themselves, just like I have."
