From: Cnidocyte discharge is regulated by light and opsin-mediated phototransduction

Figure 3

Behavioral studies of cnidocyte discharge indicate a significant inhibitory effect of light intensity on cnidocyte function. (A) Representative data for cnidocyte discharge assay. In this experiment stenotele cnidocytes were captured using gelatin-coated lengths of monofilament under different experimental conditions. (B) Significantly fewer cnidocysts were recovered from assays conducted in bright blue light (470 nm; 2.8 W/cm2) than in dim trials (470 nm; 0.1 W/cm2). Bright light suppression was ablated by the presence of the CNG inhibitor cis-diltiazem. Area between dashed lines in (A) = gelatin matrix; asterisk = monofilament; arrow heads = stenotele cnidocytes.
