Today is my birthday, and I am determined to relax, no matter how much work it takes.
Fortunately I have great help from people like my good friend Jim of Clark’s Grove, who wrote today’s guest post. With a few forthright words about nematodes, Jim has helped me understand my true role in the universe and has placed my birthday in its proper context. To anyone who says “host” is not a decent job description, I say, ‘Pal, we’re all hosts.’
Here’s Jim’s post:
I suspect that many people know a lot about something which is not widely known by most other people. I am thinking about unusual information that might be gained through professional training, or from involvement in a hobby, or by somehow gaining access to unusual information. I happen to know quite a bit about nematodes, a group organisms that I think are a mystery to the general public. My knowledge of nematodes came mostly from my study of these organisms as a graduate student. I would like to share some of the information I have about these very significant and severely overlooked creatures with the hope that you will share information about something that you think has been largely ignored.
Nematodes, which are also known as round worms, are the most numerous multicellular animal on earth. There are some single celled organisms that outnumber nematodes, but nematodes have exceeded all other animals with more than one cell when counting the total number of individuals. If you removed all the soil and water from the earth and left the nematodes, the large populations of nematodes found everywhere would show you where the soil and water was previously located. Most nematodes are very small, only a millimeter or two in length, although you might have seen some of the larger parasitic ones that are several inches long in the stools of your pets. Some whales contain parasitic nematodes that are more than 20 feet long.

Nematodes parasitize just about everything including all kinds of animals and a wide range of plants. People suffer from many kinds of nematode parasites; including pin worms, hook worms, and the worms that cause trichinosis which you can get if you don’t do a good job of cooking pork. In fact, there are even some nematodes that are parasitic in other nematodes. If you look closely at the picture I provided you will see two nematodes because this is a picture of a nematode with a parasitic nematode in its body cavity. I came across this parasitized nematode during my study of free living nematodes found in soil. The drawing was done with ink on scratch board following instructions for making nematode drawings that came from a famous nematologist, Gerald Thorne. Thorne was very devoted to the study of nematodes which he was sure would be found in soil samples from the moon. He was certain of this because he knew they are found everywhere on earth.
I got started in nematology by doing a research project on plant parasitic nematodes, some of which can severely damage plants. However, most of my efforts in nematology were centered on the taxonomy of a group of free-living nematodes which led me to discover and describe a dozen new species of nematodes. Most people who work on the taxonomy of larger organisms would not expect to discover such a large number of new species. When it comes to nematodes, it is not hard to find numerous new species because most of the existing species have not been described.
I have attempted to dazzle you with some information about the wondrous group of organisms called nematodes. You probably weren’t aware of the huge number of these organisms hidden in soil and water everywhere and also found as parasites in or on many animals and plants. In fact, you might have harbored or still be harboring some of them, yourself. I think I was infested with pin worms when I was a kid. In those days many school children suffered from infestations of these very small worms. I wonder if you have information about something that is unusual or not well known to the general public.
Are you familiar with something that is being ignored?
