Phylum Nematoda Part 1: Introduction to the Roundworms

Continuing through Ecdysozoa, we get to Nematoda, which contains several hundred thousand profoundly abundant species of roundworms. Where do nematodes live and what are their characteristics? Which ones are free-living and which are parasitic? What is the significance of C. elegans? Let's find out!

    These videos are really cool,thank you for making such an in-depth explanation on all the phyla;As an entomology enthusiast,I’m really excited for when you cover Arthropoda,I feel like there’s a lot you can cover with Arthropoda and it’s always fun to learn more about these animals.

    Great video! Quick note, though... C. elegans don't normally (without specific mutations) bag. Embryos are usually laid prior to larval development. Though, inducing the bag phenotype can be a useful marker for strain construction.

    Random food for thought but if you have a gumption to play with a few 100 million pets (and control fungus gnats, mites, and other nasties in your garden) you can usually pick up a tub of these guys at your local garden center. They are by far one of my favorite methods of integrated pest management!

    Ascarids and Nematodes are some of my best friends. I’ve taken many of them on fishing expeditions. I had the rather unpleasant experience of the marine nematode called the bloodworm in common parlance (Glycera dibranchiata ?) burry it’s impressive 4 “teeth” into the heel of my thumb. I suppose I had it coming since turn-about is fair play ! Thank you Professor Dave for your always excellent videos. I invariably learn several interesting and thought provoking things. Cheers !

    Well, although your experience sharing is much appreciated, Glycera dibranchiata, the bloodworm is not a Nematode, but an annelid from the phyllum Annelida, with cylindrical, segmented bodies. Glycera are classified in the Polychaeta, usually marine worms, while the Oligochaeta, the earthworms and leeches, are their mostly terrestrial and freshwater representants. The groups Oligochaeta and Polychaeta are the two major groups within Annelida. Moreover, worms, in the general sense, are much diverse and this body plan is quite common in nature, so caution must be taken when discussing your worms hahaha. I hope to have been helpful.

    6:56 “Most species lay microscopic eggs that are protected by a tough outer shell, though some species, like C. elegans, instead display a behaviour known as “Worm Bagging” or “Facultative Vivipary”, where fertilized eggs hatch inside the parent and the larvae then consume their parent from within to emerge as juveniles.” This makes it sound like this worm bagging is the default mode of reproduction in C. elegans, which isn’t true. Like other nematodes, C. elegans lays eggs, and worm bagging only occurs when there are developmental defects in the vulva/gonads, or the worm is physiologically stressed.
