Introduction
Question 1 - Is Light Modulation Ancestral in Cnidaria?
- Previous research indicates light modulates nematocyte firing in hydra. See Plachetzki nematocyte firing.
- Do cnidarians from other classes show a similar response to light, with respect to the modulation of nematocyte firing?
- In addition to the hydrozoan hydra, we tested light modulation of nematocyte firing in one scyphozoan (Aureila), and two anthozoans (Anthopleura and Haliplanella).
Question 2 - Why Light modulation?
H1: Pleiotropy
Molecular components are shared between chemo- and photo-reception. Do opsins artifactually affect the chemo-transduction cascade?
H2: Light cues signal reliability of different feeding modes
- Bright light could favor transition to relying on photosynthetic symbionts.
- Dim light could signal nightfall, after which zooplankton prey are more active
