Under the Microscope and in Your Plant

Gastrotrichs are a type of metazoan that ranges from 50-800 µm long and can be identified under 100x magnification. Gastrotrichs are colorless with cilia attached to their head. They have adhesive tubes on their posterior end that helps them temporarily attach to surfaces. Typically, gastrotrichs are predominant in the autumn, however the exact reason for this is unknown. Their abundance does not indicate any specific plant conditions. Their average life cycle is between 3 to 21 days long. Newly hatched gastrotrichs are about two-thirds the length of an adult and are genetically identical to their mother.

Interesting Facts

• Older gastrotrichs become hermaphrodites and grow both sperm sacs as well as develop sexual eggs
• Living gastrotrichs are too active for detailed observation, so scientists have slowed them down using cocaine
