  2. The tegmentum region in the zebrafish midbrain integrates light signals from both the eyes and the pineal organ (the "third eye") to coordinate spatial orientation. This neural integration allows the fish to adjust its up-and-down swimming behavior based on the specific wavelengths of ambient environmental light.

  3. The freshwater #alga Trachydiscus minutus survives in extreme low-light environments by utilizing a specialized protein architecture to capture far-red light for photosynthesis, relying entirely on ordinary chlorophyll a.
