Sensory structures called phasmids can be found near their anus, which serves as the end of the pseudocoel of these triploblastic creatures, which include biological superstar C. elegans.
Genera in this phylum include Haemonchus, Necator, Ancylostoma, and Trichuris. These creatures' ameoboid sperm is believed to be the only eukaryotic cell without G-actin, and they mate through the use of a chitin- coated spicule and often with the aid of specially bent tails. To avoid dessication, their epidermis secretes a keratin cuticle, which also means that they molt. Some also have cilia, but all move primarily through their hydrostatic skeleton.
