Welcome to the next installment in the earthworm series. This is the second in a set of three, which aims to provide a brief overview of some of the most notable and often-discussed species of earthworms. If you have not read the first article, we covered the common earthworm and the tiger worm in that one. In this sequel, we will be looking at pheretima earthworms and the Asian jumping worm. These two species are pretty well-established in the helminthology world, though sources on the pheretima earthworm seem to provide conflicting accounts about their physical characteristics.
