1. Other larvae show negative phototaxis by swimming away from the light. 2. The larvae display mixed phototaxis , some negatively phototactic larvae are tracked. 3. The three opsins there mediate phototaxis all the same way via depolarization, 4. Two types of positive phototaxis are observed in prokaryotes. 5. Phototaxis there is mediated by two pairs of more complex pigment cup eyes.6. This asymmetric positioning of the eyespot in the cell is essential for proper phototaxis . 7. "Platynereis dumerilii " nectochate larvae can switch between positive and negative phototaxis . 8. :House flies ( and many flying insects ) display positive phototaxis when trapped or stressed. 9. Phototaxis there is mediated by simple eyespots that consists of a pigment cell and a photoreceptor cell.10. A pair of these eyes mediate phototaxis in the early " Platynereis dumerilii " trochophore larva.
