Primary Assay — Starlet Sea Anemone
Feeding Response (Prey Capture)
Nematostella vectensis
Nematostella captures prey with nematocyst-bearing tentacles and opens its mouth in response to glutathione — a chemical signal from damaged prey tissue. Capture time, handling duration, and GSH threshold quantify feeding behavior.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Nematostella vectensis.
| Parameter | Unit | Description |
|---|---|---|
| Tentacle capture time | s | Time to ensnare prey |
| Prey handling duration | s | Ingestion processing |
| Feeding response threshold | µM GSH | Glutathione concentration for mouth opening |
| Mouth opening duration | min | Time mouth stays open |
