We observed our aquariums under a light microscope. There was a lot of activity. Most organisms were seen surrounding the plant material. The Gastrotrich was observed near the bottom, just above the soil line. Also, observed were Rotifers, Diatoms, and Perimysium.
Tachysoma: "A hypotrich with well developed (immotile) dorsal bristles "(Patterson, 1992)
In most Gastrotrich species female eggs develop without fertilization (parthenogenesis); therefore, males are rare. Gastrotrich lack circulatory, respiratory, and skeletal organ systems. (Ranis, et al, 1996).
