Definition
Aphasmidia is a class within the phylum Nematoda (roundworms). These nematodes lack phasmids, which are sensory organs located near the tail. Aphasmidia typically inhabit freshwater or soil environments. They often include parasitic species that affect plants or invertebrates. Think of them as the 'sensory-deprived' group of roundworms, although they still manage to navigate their environments! 🏞️ They are also characterized by having a simple excretory system.
