Figure 3. Nematostella locomotor activity has an endogenous rhythm.

Figure 3

(A). Nematostella locomotor activity under a 12 : 12 h light : dark cycle (LD) at 23 °C. (B). Nematostella locomotor activity in constant dark (DD) at 23 °C. (C). Nematostella movement in constant light (LL) at 23 °C. (D). Nematostella locomotor activity in LD at 18 °C. White bars indicate light hours, black bars indicate dark hours, and gray bars indicate illumination conditions different from an LD cycle (dark instead of light; light instead of dark).
